Abstract:
Abstract Dynamically changing economic conditions influence the growing demand of various freights transportation. Inevitably, the demand for heavy and oversized freight transportation is increasing, which is quite problematic. In many cases, it is very difficult to standardize the technology of heavy and oversized freight transportation. Decisions are necessary, which would allow to deliver heavy or oversized freight to the destination place, allocating fewer funds as possible for infrastructure improvements, choosing the most appropriate mode of transport for such freight transportation or using advantages of multimodal (combined) transport. In this article there will be selected methodology of heavy and oversized freight transportation system, carrying heavy and oversized freight by road transport. There will also be made an approval of this methodology, based on a hypothetical route within Lithuanian territory.

Abstract:
<p>The dedicated all-cargo aircraft market is vital to the global economy. Freighter aircraft now carry around 56 per cent of world air cargo traffic. Using an in-depth case study research design, this study examined the Qantas Freight Boeing B747-400 and B767-300 freighter aircraft route network design during the 2017/2018 Northern Winter Flight schedule period, which was in effect from the 29th October 2017 to March 24th, 2018. The qualitative data were examined by document analysis. The study found that Qantas Freight deploy their leased B747-400 freighter aircraft on a route network that originates in Sydney and incorporates key markets in Thailand and China with major markets in the United States. The Boeing B767-300 freighter aircraft operated 5 services per week on a Sydney/Auckland/Christchurch/Sydney routing as a well as a weekly Sydney/Hong Kong/Sydney service. The Boeing B747-400 freighter services could generate 114,755,020 available freight tonne kilometres (AFTKs) over the schedule period. The Boeing B767-300 freighter aircraft could generate 46,974,1440 AFTKs. The Qantas Freight route network and freighter fleet is underpinned by Australia’s liberalized freighter aircraft policy, the “Open Skies” agreement between Australia and China – which permits the onward carriage of cargo traffic across the trans-Pacific – and the liberalized “open skies” agreement with New Zealand.</p>

Abstract:
This article demonstrates that new industrial technology caused a revolutionary decline in nineteenth-century freight rates. This overturns Douglass North's well-known conclusion that organizational improvements were the dominant source of savings. While North's American freight rate series declines prior to the use of the metal steamship, British rates decline only modestly prior to 1850 and then rapidly as metal steamships come into use. Cotton freights dominate North's index and declined when cotton became more tightly packed for shipment. Metal ships and steam propulsion, however, caused a general decline in freight rates after 1850.

Abstract:
A concept is introduced for a new mode of freight transportation in which general cargoes are “pumped” through underground or under-water pipelines. The concept itself is not new, but a recent technical breakthrough has transformed the technology to a point where tube freight could become a cost-effective alternative to surface freight, in particular, to truck and air freight. Although the study of this new mode is at the conceptual level, only the concept is based on an extensive body of knowledge, developed for pneumatic capsule pipelines for moving granular products, a well-proven technology backed by considerable operational experience. Tube freight has the potential to displace many long-haul trucks from U.S. highways. The principal driving forces are economics, safety, energy-conservation, and environmental impact. The system operates automatically under computer control, and deliveries are precisely predictable for meeting just-in-time production requirements. Preliminary studies suggest that tube freight is technically and economically feasible. The technology involved is state-of-the-art and nothing new needs to be invented. The major obstacle to tube freight’s implementation is that the concept is little known, and even less understood, by the transportation community.

Abstract:
Based on global experience, the article proves the necessity of improving the analysis of regulatory impact of legislative acts, which is the main instrument of state regulation quality assurance. Recent years display the trend of temporal inland traffic freight railway tariffs increase. The last increase was approved by the corresponding Order of the Ministry of Infrastructure of Ukraine dd. August 11, 2021 qualified as a regulatory act, which is subject to compulsory regulatory impact analysis according to the Methodology approved at the national level. The national methodology does not provide for assessment of impacts on state economy. In view of this, the assessment was completed for the possible impact of regulatory act work on the state economy according to the methodological approach developed by the State Organization “Institute of the Economy and Forecasting of the National Academy of Sciences of Ukraine”, which main point is a more comprehensive and sophisticated quantitative assessment of the direct regulatory impact on the field of economic interest of both citizens, economic entities, state, and the society in general (national economy). The impact assessment of the freight railway tariffs’ increase on national economy followed two perspectives: the possible impact on GDP and the competition within the traffic infrastructure of Ukraine. The contribution of JSC “Ukrzaliznytsia” into GDP of Ukraine is computed based on freight railway tariffs increase. The article proves that the Order of the Ministry of Infrastructure of Ukraine will have the effects on intermodal competition within the transport system of Ukraine through the redistribution of the freight traffic as, on the one hand, certain off-grade freights will be handled by the river and motor transport and, on the other hand, specific 3rd rate class freights will be handled by the rail transport. Such redistribution will have positive effects for the competitive position of rail transport on the inner freight traffic market because the loss of some off-grade freights, which transport is unprofitable, will not have a negative impact on rail facilities.

Abstract:
North American commuter railroads run their trains largely on tracks shared with freights (and in the northeastern US, often shared with intercity passenger trains). This sharing makes commuter rail relatively affordable to implement. However, as freight traffic grows, so does the potential for delays. If freight and commuter operations affect each other’s performance, it may be necessary to consider separation measures, not adding to the existing shared-track capacity. Temporal separation can work on low-volume operations. Busier lines may require physical separation, which can be implemented in several forms for trunk lines (grade separation at junctions, freight bypass, partial trunk line separation, and full trunk line separation), as well as physical separation in downtown areas. This article identifies these separation options, describes their attributes, presents representative examples, and outlines criteria for evaluation.

Abstract:
Due to the presence in the operating fleet of freight cars with a base of over 10 m, as well as the practical impossibility of symmetrically placing loads with a weight corresponding to the nominal carrying capacity on open rolling stock, adjustments to the existing asymmetrical loading standards are necessary. To this end, it is proposed to apply a comprehensive methodology for determining the allowable parameters of asymmetrical placement of freights, based on a combination of strength criteria of the bearing elements of cars, ensuring the normative level of dynamic qualities and stability of the loaded car. The article provides an example of determining the permissible parameters of the joint lateral and longitudinal displacement of the total center of gravity of the car (ЦТгр°), loaded to the nominal capacity. According to the results of the studies to determine the allowable values of longitudinal and lateral displacement ЦТгр° with unbalanced placement within the loading platform of the car, including the presence of a joint displacement, it was found that to improve the efficiency of using freight cars with an increased base, it is advisable to update the current offset standards of ЦТгр°. It is recommended to take the values of longitudinal displacement ЦТгр° for cars with a body base of 14.6 and 19.0 m respectively 1.46 and 2.11 m for freight with a total weight of 50 tons; 1.10 and 1.43 m for freight with a total weight of 60 tons; 0.22 and 0.28 m – for freight with a total weight of 67 tons. When placing freights with a total weight of over 67 tons with a height of center of gravity of 2.0–2.2 m on 4-axle freight cars with an axle load of 230.5 kN without limiting the permissible driving speeds, it is recommended to use a graphical method for determining the joint (longitudinal and transverse) displacement ЦТгр°. With an increase in the joint displacement parameters ЦТгр°, it will be necessary to limit the speed of the car in the curved sections of the track and to the lateral direction on the turnouts.

Abstract:
Currently, a project for organizing the transportation of perishable freights by “Cold Express” trains is under development, which is a new transport product aimed at delivering food, agricultural raw materials and other highly profitable goods to cities where regular container trains are impractical. The article discusses the economic efficiency of the investment project for organizing the transportation of freights in regular refrigerated container trains on the example of the Vladivostok—Moscow—St. Petersburg route, taking into account the arrangement of at least 18 container sites capable of handling transit container trains. Transportation according to the “Cold Express” concept involves the delivery of freights on the Vladivostok— Moscow—St. Petersburg route to associated large cities by container train loaded with refrigerated and insulated containers, according to a developed schedule with a known arrival and departure time. Capacity of the freight transportation market on the pilot route of the “Cold Express” is 2.0 million tons with the development of transportation in both directions when reaching the design capacity. Freight traffic will be formed by 23 stops on the route, 2 port hubs, 2 border land crossings with a traffic size of 7 pairs of trains per week. As part of the project, an assessment was made of the need for the local reconstruction of passing stations and equipping them with new ones or refurbishing existing container terminals. At the same time, the commissioning of these terminals is supposed to be gradual within 7 years of the project, which also allows gradually increasing the freight base and improving the quality of transportation. The article presents the results of calculations of the commercial efficiency of the project for the Russian Railways as the owner of the infrastructure, carrier and operator of these container terminals, which show its high prospects. Even with an incomplete train load predicted due to uneven density of freight traffic, the net discounted payback period is 10 years.

Abstract:
Currently, long-distance freight transport is shifting towards multimodal transport, the combination of multiple freight transport modes. Multimodal transport enables enterprises with the same logistics function to operate on the same level of the supply chain. Through horizontal cooperation, these enterprises can give play to their advantages, make up their deficiencies, improve service levels, reduce cost input, and thereby enhance market status. Therefore, multimodal transport is an intensive development model that promotes the alliance between giants. The reasonable path design and planning (PDP) and investment and construction mode (ICM) of the multimodal transport network help freight demanders, as well as multimodal freight transport platforms, obtain the maximum profit. Therefore, this paper explores the PDP and ICM of the multimodal transport network based on big data analysis. Firstly, the influencing factors and behavioral features of multimodal transport were deeply examined, drawing on the logit model and the big data on multiple freight services, namely, railway transport, highway transport, waterway transport, and airway transport. After classifying the freights, the authors analyzed the modeling and decision-making of path design and optimization (PDO) for multimodal transport network. The proposed model was proved effective through experiments. This paper theoretically explores the goals, principles, and needs of path selection in the modern transportation industry. In a realistic sense, the research findings help decision-makers optimize their decisions on the multimodal transport network and operate the network at the minimum transport cost.

Abstract:
The technical feasibility of a heavy haul freight using WDPS (Wireless Distributed Power System) was verified for the first time in Korea. That consisted of a master locomotive, 50 freights and a slave locomotive. The master and slave locomotives were equipped with WDPS to distribute traction and braking control command data. MIMO-OFDM, which is strong in multi-path, was applied to the WDPS, and a repeater was installed on the 25th freight to secure coverage even with signal attenuation according to the terrain (curve, gradient) of the driving section. The test was carried out at an average speed of 100 km/h in the approximately 21 km from Jillye station to Busansinhang station in Korea. As a result of the test, it was confirmed that the traction function, braking function, pantograph control function, MCB function, and safety circuit function of the heavy haul freight using WDPS were perfectly controlled. Additionally, the air braking time was reduced by about 50% compared to the centralized control as the braking was controlled by two locomotives at the same time. For the first time, the operational feasibility of heavy haul freight using WDPS based on MIMO-OFDM in the 2.4 GHz/5 GHz band with a relatively short propagation distance was verified.

Abstract:
The main purpose of this project was to examine the reliability of Value of Time for freight applications by comparing the functionality of the Freight Value of Time modelling concept, with the functionality of the freight market. The research questions of this report are: How can the Freight Value of Time concept fulfil the requirements that decision makers in international freight have on the reliability of the modelling outcome? What are the differences between the multimodal and the unimodal applications of Value of Time in terms of validity? Within the scope of this study; modelling in the field of freight, logistics and supply chain management are presented with focus on Value of Time models. An overview of common freight models is initially presented as a starting point for literature reviews on trends and characteristics of the freight market , and on Freight Value of Time. These two literature reviews constitute the main methods of information retrieval on which the later analyses are based. The trends and characteristics of the freight market section provided the general requirements and a context for modelling freight, which was used for analysing and discussing Freight Value of Time. Additionally, a survey was performed in order to provide some insight into the requirements that analysts and decision makers have. The survey results were presented in the form of six examples of Swedish decision makers in freight. However, the survey results were deemed unsuitable for general conclusions due to a low response rate (6 out of 60). The analysis chapter of the report is divided into three parts; a general analysis section, a validity test of Freight Value of Time and a conceptual feasibility example. The general analysis focussed on issues with Freight Value of Time, the survey, freight market trends and multimodality. In the general analysis Global production networks and supply chains were identified as major trends and were used as the main modelling context when analysing Value of Time as a modelling concept for freight. The rest of the general analyses focuses on how well the modelling concept Value of Time corresponds to the functionality of the market. The validity test section showed that there are some possible issues with Freight Value of Time and that they can possibly be attributed to poor data availability and high aggregation levels. Therefore, the feasibility example study was performed for a conceptual case where data that is often missing was available. The specific data was characterised as supply chain data, which could be available to external analysts if the companies decide to share it. The feasibility study thereby tested if it actually was the lack of data that is the main reason for models including Freight Value of Time to lack validity according to the validity test. Access to data was found to be an important factor when creating a freight model with Value of Time, because by adding the supply chain data the performance of Freight Value of Time in the validity test was improved. However there were still potential issues with using Freight Value of Time concerning testing and verification in relation to the complexity of large scale freight models and the complexity of multimodal freight transport. The main issues with Value of Time identified throughout the project were: 1. Discrete choice model selection 2. High aggregation levels due to lack of data 3. Explanatory variables 4. Identification of decision makers 5. Transport flow heterogeneity A set of four recommendations for analysts were devised from the hypothesis of: Models using Freight Value of Time are not reliable enough to be used in practise. The recommendations to analysts interested in Freight Value of Time were: - The specific model should be verified and validated before being used, which is probably best done for the specific application with a standardised verification and validation method such as the VV&A (used by Department of Defense in the USA). - Freight Value of Time is best used for unimodal applications, but for multimodal applications it could be reliable enough if the model is properly adapted to the complexity of the reality which is modelled. - The higher the complexity of a modelling scenario, the more data is needed. Therefore an analyst needs to make sure that this trade-off is kept at a level where the results fit the requirements of the application. - Low aggregation levels benefits the accuracy of the model, but increase the amount of calculations. It is therefore good to be aware of the risk of calculation errors. Summarised, the report concludes that Value of Time is sometimes the best method at hand but difficulties in gathering data can affect the accuracy negatively. Furthermore the complexity of multimodal freight transportation makes Value of Time less valid than for unimodal freight.

Abstract:
O transporte marítimo de petróleo e derivados é componente fundamental da cadeia de suprimento da indústria do petróleo, integrando fornecedores e clientes localizados em regiões geográficas distintas. Neste contexto, os valores de fretes praticados possuem grande impacto no comércio internacional destes bens. O objetivo deste trabalho é verificar o desempenho de modelos de Regressão Dinâmica em previsões de frete marítimo de curto prazo do mercado spot de uma rota de exportação de petróleo do oeste da África para a China, comparar a capacidade preditiva do modelo com métodos tradicionais, vastamente discutidos na literatura, como Amortecimento Exponencial e modelos ARIMA e projetar cenários para avaliar como as variáveis explicativas presentes no modelo de Regressão Dinâmica proposto neste estudo afetam o frete marítimo. O produto desenvolvido nesta dissertação mostrou a viabilidade de os modelos univariados e causais serem utilizados como ferramenta de previsão da taxa frete de navios petroleiros. Como forma de validação, os resultados foram comparados aos obtidos com a metodologia vigente em uma grande empresa de petróleo do Brasil. O protótipo de sistema de previsão proposto, via Regressão Dinâmica, apresentou resultados satisfatórios e desempenho superior ao obtido através da metodologia da empresa de petróleo.
Crude oil and oil products seaborne transportation is a key component of the petroleum industry supply chain, integrating suppliers and customers located in different geographic regions. In this context, the freight rates practiced have a great impact on the international trade of these goods. This work aims to verify the performance of Dynamic Regression models in short-term maritime freight forecasts of the spot market of an oil export route from West Africa to China, to compare the predictive capacity of the model with traditional methods, widely discussed in the literature, such as Exponential Smoothing and ARIMA models and to design scenarios to evaluate how the explanatory variables present in the Dynamic Regression model proposed in this study affect freight rate. The product developed in this dissertation showed the viability of the univariate and causal models being used as a forecasting tool for the oil tankers freight rate. As a form of validation, the results were compared to those obtained with the methodology of a large Brazilian oil company. The proposed prediction system prototype, through Dynamic Regression model, presented satisfactory results and performance superior to that obtained through the methodology of the oil company.

Abstract:
This thesis investigates three salient areas of interest in the structure of freight rates in the shipping market, with a particular focus on the tanker and dry-bulk sectors, using recent econometric and time series techniques. The questions asked are: 1) do spot freight rate levels follow a fractionally integrated process, as opposed to being stationary or non-stationary, as had previously been proposed; 2) does spot freight rate volatility also follow a fractionally integrated process; and 3) do freight rates exhibit conditional skewness and kurtosis? It then evaluates the impact that these factors have on the risk exposure of market participants. These concepts are further tested in terms of their respective forecasting performance, relative to other more standard econometric techniques. An ongoing issue in the shipping literature is whether spot freight rate levels follow a stationary or non-stationary process. This thesis provides another dimension to this discussion by arguing that spot freight rate levels follow a fractionally integrated process. The rationale behind this argument is the fact that the supply and demand dynamics in this market mean that although freight rates are mean-reverting overall, the process of mean-reversion occurs with a delay, which is exactly how one would expect a fractionally integrated process to behave. Although in-sample results were promising in that fractionally integrated models are found to outperform their stationary and non-stationary counterparts across sectors and vessel sizes, out-of-sample forecasts indicate that models that assumed stationarity or non-stationarity outperformed these models, depending on the sector and vessel size. Additionally, the thesis extends this debate to the volatility of these spot freight rate levels, where it is proposed that volatility also follows a fractionally integrated process. In-sample results from the estimation of Generalised Autoregressive Conditional Heteroscedasticity (GARCH), Integrated Generalised Autoregressive Conditional Heteroscedasticity (IGARCH) and Fractionally Integrated Generalised Autoregressive Conditional Heteroscedasticity (FIGARCH) models indicate that FIGARCH models outperformed the other two models across all sectors and vessel sizes, however, when calculating the respective out-of-sample Values-at-Risk for each 18 vessel type, non-parametric models are found, in most cases, to outperform their parametric counterparts across sectors and vessel sizes. This thesis finally examines whether freight rates exhibit conditional skewness and kurtosis, where the shape of the supply function in the shipping freight markets indicates that these would not be constant over time, as is assumed by other standard models. Results for the in-sample period indicate that the Generalised Autoregressive Conditional Heteroscedasticity with Skewness and Kurtosis (GARCHSK) models outperformed GARCH and FIGARCH models. This being said, when calculating the respective out-of-sample Values-at-Risk for each vessel type, non-parametric models are found, in most cases, to outperform their parametric counterparts across sectors and vessel sizes.

Abstract:
Today’s logistics practices are moving from inventory-based push supply chains to replenishment-based pull supply chains, leading to a lower and less centralized inventory, smaller shipment sizes, and more just-in-time deliveries. As a result, industries are now demanding greater reliability in freight transportation. Delays and uncertainty in freight transportation translate directly into additional inventory, higher manufacturing costs, less economic competitiveness for businesses, and higher costs of goods that are being passed on to the consumers. Given the growing demand in freight transportation, the emerging needs to better understand freight behavior for better policy and investment decisions, and the increasing role of reliability in freight transportation, this research aims at providing a) better understanding of how the freight system users value travel time reliability in their transportation decisions, and b) advanced methods in quantifying the user’s willingness to pay for the improvement of transportation related attributes, particularly travel time reliability. To understand how the freight industry values travel time reliability in their transportation decisions, and particularly the presence of user heterogeneity, this research designed and conducted a stated preference (SP) survey for freight users in road transportation. Based on the feedback received during the pilot stage, reliability was measured as the standard deviation of travel time and presented as a frequency of on-time and late delivery in the choice scenarios. The survey collected 1,226 responses from 159 firms in Florida between January and May 2016 via online and paper methods. Various modeling approaches were explored to estimate the willingness to pay (WTP) measures among freight users, including multinomial logit (MNL) and mixed logit model. Market segmentation and interaction modeling techniques were employed to investigate preference variations among user groups, commodity groups, product type, and various other shipment characteristics, including shipping distance and weight. In general, across all groups in the sample, values of $37.00 per shipment-hour ($1.53 per ton-hour) for travel time savings and $55.00 per shipment-hour ($3.81 per ton- hour) for improvements of reliability were found in this research. Furthermore, while investigating the effects of shipping characteristics on the user’s preference in WTP, the results suggested that shipping distance and weight were the two most important variables. The results of the study help advance the understanding of the impact of the performance of transportation systems on freight transportation, which will lead to policy and investment decisions that better serve the needs of the freight community.

Abstract:
This research focuses on fleet management in freight transportation systems. Effective management requires effective planning and control decisions. Plans are often generated using estimates of how the system will evolve in the future; during execution, control decisions need to be made to account for differences between actual realizations and estimates. The benefits of minimum cost plans can be negated by performing costly adjustments during the operational phase. A planning approach that permits effective control during execution is proposed in this dissertation. This approach is inspired by recent work in robust optimization, and is applied to (i) dynamic asset management and (ii) vehicle routing problems. In practice, the fleet management planning is usually decomposed in two parts; the problem of repositioning empty, and the problem of allocating units to customer demands. An alternative integrated dynamic model for asset management problems is proposed. A computational study provides evidence that operating costs and fleet sizes may be significantly reduced with the integrated approach. However, results also illustrate that not considering inherent demand uncertainty generates fragile plans with potential costly control decisions. A planning approach for the empty repositioning problem is proposed that incorporates demand and supply uncertainty using interval around nominal forecasted parameters. The intervals define the uncertainty space for which buffers need to be built into the plan in order to make it a robust plan. Computational evidence suggests that this approach is tractable. The traditional approach to address the Vehicle Routing Problem with Stochastic Demands (VRPSD) is through cost expectation minimization. Although this approach is useful for building routes with low expected cost, it does not directly consider the maximum potential cost that a vehicle might incur when traversing the tour. Our approach aims at minimizing the maximum cost. Computational experiments show that our robust optimization approach generates solutions with expected costs that compare favorably to those obtained with the traditional approach, but also that perform better in worst-case scenarios. We also show how the techniques developed for this problem can be used to address the VRPSD with duration constraints.

Retail manufacturers often expedite inbound freight shipments from contract manufacturing bases to their distribution centers in destination markets at high cost to improve service levels to their wholesale partners and retail arm. The current process around these decisions has yielded lower than anticipated improvements to service level. This thesis (1) reframes the goal of expediting inbound freight in quantitative, measurable terms that more directly impact the business outcomes, (2) develops an optimization model to select a set of freight shipments to expedite and best improve service, and (3) uses the optimization model to estimate potential improvement magnitudes with strategic changes.

Abstract:
Japanese National Railways (JNR) has been privatized in 1987. As Kurosaki [45] stated, during the era of JNR, it accumulated heavy debts, especially in the freight operating area as railways in Japan are passenger-dominated. The conglomerate of Japanese domestic railway operators consists of 6 passenger companies and the seventh one is dedicated to freight operations and transport. Passenger rail transport companies are divided regionally and certainly operate passengers’ trains only. These companies are Hokkaido Railway Company (JR Hokkaido), East Japan Railway Company (JR East), West Japan Railway Company (JR West), Central Japan Railway Company (JR Tokai), Shikoku Railway Company (JR Shikoku), Kyushu Railway Company (JR Kyushu) and additionally Shinkansen Holding Corporation for high-speed rail transport [40]. By the way, it also includes the Railway Communication Company, Rail Information Systems Company, Railway Technical Research Institute, and Japanese National Railways Settlement Corporation [41]. Each of these transportation companies has in disposal their infrastructure and facilities in contrast to Japan Freight Railway Company (JR Freight), the company which operates freight transport. According to [45], JR Freight forms a vertically separated structure, while all the JR passenger companies comprise a vertically integrated structure. JR Freights consists of 6 branches: Kyushu, Kansai, Tokai, Kanto, Tohoku, Hokkaido [40]. JR Freights rents infrastructure from other companies [45], which makes freight transport dependent on time windows between passengers’ transport (more information related to that topic is mentioned hereafter). It does not have own its tracks; however, it has in disposal its own stations, yards, and facilities for freight trains. JR Freights, as many other companies in Japan (e.g. Shizutetsu, Suzuyo – sample companies are mentioned after discussions on the topic during grant in Japan with Prof. Koichi Shintani – private correspondence) is carrying about several different kinds of business, i.e. freight services, warehousing, car park operation, advertising, indemnity and other non-life insurance agency services, vehicle services, general civil engineering and construction design, project execution and management, incidental and related business operations

Abstract:
Freight represents approximately 30% of all transportation-related emissions in the U.S., but local climate action plans (CAPs) and freight plans often place limited emphasis on freight emissions reduction strategies. The objective of this report is to examine and present strategies for the City of San José, California to reduce GHG emissions from freight. The authors conducted a geospatial analysis of freight data related to San José, and an analysis of relevant literature and successful freight reduction strategies implemented globally. The report also provides key objectives and generalized strategies to reduce GHG emissions from freight as well as specific recommendations for San José. The analysis and recommendations can guide future transportation planning within San José and help inform other municipalities seeking to reduce their own community wide freight emissions.
