This thesis presents new insights and techniques for the analysis and design of autonomous or technology-assisted ("intelligent") transportation systems. The focus is on cooperative, on-line planning and control, of a fleet of transport vehicles with limited carrying capacity, where new transportation demands enter the system in real time. The study extends an existing probabilistic framework which has provided numerous insights about vehicle scheduling and routing problems since its inception. Additionally, the thesis provides algorithms and new probabilistic cost bounds, for optimal bipartite matchings between large sets of random points and optimal stacker crane tours through large sets of random demands. A recurrent theme of the thesis is that capacity-constrained vehicles must drive passenger-less, inescapably, for some positive fraction of time (in almost any practical setting). Moreover, under probabilistic modelling for the uncertainty of demand, one can predict the aforementioned fraction precisely, using strong Laws of Large Numbers arguments; it relates to a quantity known as the Earth Mover's distance (EMD), described by a fundamental problem in transportation theory. Since the existence of an unavoidable extra cost term has significant implications, e.g., for operational budgets of shared-vehicle systems, the results illuminate a phenomenon whose neglect could prove an unfortunate oversight. To the author's knowledge, this connection of the EMD to on-line vehicle routing is novel. The thesis also provides a new study of the practical considerations imposed by the "street rules" ubiquitous among ground-based transport problems. A new efficient algorithm for the Bipartite Matching problem for points on a roadmap is given. Also given is a new explicit formulation of the EMD on road networks; very few explicit formulas for EMDs have been known previously.

Feeding the world's growing population in an environmentally sustainable way is a complex social and engineering challenge. In this thesis, we develop a novel method for assessing the number of people that can be fed sustainably in a particular region for given natural resources and diet (the carrying capacity). A quantitative assessment of carrying capacity provides insight into the food security of the study region as well as the stress on the environmental system; in addition, this methodology can be used to assess the carrying capacity under a variety of policy interventions such as increasing yields, changing diets, or expanding irrigation infrastructure. The carrying capacity assessment uses optimization methods that find the cropping pattern that maximizes population subject to land, water, and diet constraints, considering a range of rainfed and irrigated crops. A data fusion procedure estimates the regional water and land resources needed to assess carrying capacity by combining measurements from diverse hydrologic and agronomic sources, including remote sensing data. Our carrying capacity methodology is illustrated with a case study of food security in China. China has historically been largely food self-sufficient, although its food imports have been increasing since the year 2000. We find that the population in China was well below the country's carrying capacity in the year 2000 given the diet and yields in that year. However, the population's changing diet - especially the growing preference for meat - is exacting a growing toll on land and water resources. We find that under a more recent diet (2013), China is not likely to be food self-sufficient, even with major investments in irrigated agriculture, without substantial increases in crop yield.

Full textIncreasing interest in driving for pleasure has put a burden of crowding and over-use on many of our nation's scenic highways. The carrying capacity concept says that there is an acceptable level of use or change for a resource beyond which that resource will be significantly degraded. This thesis examines the applicability of this concept to the problems of crowding and over-use of scenic roadways.
This study developed as an attempt to bridge the gap between recently developed carrying capacity models in recreation resource management and planning and the specific problems of scenic roadways. While carrying capacity theory and practice have produced good models, the unusual characteristics of scenic roadways challenge the direct application of these models.
A questionnaire was distributed to scenic roadway designers, planners, and managers; roadway researchers; carrying capacity researchers; and recreation resource managers nationwide. Respondents answered questions about the value of carrying capacity for managing scenic roadways, about perceived problems in implementing a carrying capacity program for scenic roadways, about the appropriate scope of a carrying capacity management tool for scenic roadways, and about needs for future research to support development of a carrying capacity model for scenic roadways.
Responses to the questionnaire indicate strong support for developing a management tool for scenic roadways based on the carrying capacity concept. Responses support a broad-based approach to addressing the carrying capacity of scenic roadways, looking at both the roadway and lands adjacent to the roadway in attempts to determine carrying capacity.

This research focuses on Taiwanese and Korean visitors in Yehliu Geopark. The purpose is, by means of visual approach, to measure social carrying capacity and the factors correlating with carrying capacity evaluation. Image capture technology was also used on a series of photographs to simulate the number of visitors in Yehliu. A random sample of 319 visitors was surveyed during the spring and summer of 2008. Major findings of this study are summarized as followed: (1) The visitors’ crowding perception and acceptability vary with their nationality and scenic areas. (2) The number and distribution of visitors influence their evaluations of crowding perception and acceptability. (3) For Taiwanese visitors, the social recreational carrying capacity of Candleholder Rock Area is 93 visitors, and 90 visitors in Queen’s Head Area. For Korean visitors, the social recreational carrying capacity of Candleholder Rock Area is 120 visitors, and 108 visitors in Queen’s Head Area. Besides, the finding based on monitoring are as followed: (1) The number and distribution of visitors change tremendously with seasons and scenic areas. (2) It was found that 70% of visitors went directly into Candleholder Rock Area, while 30% did so in Queen’s Head Area. (3) Visitors stay in Candleholder Rock Area for about 14 minutes and roughly 30 minutes in Queen’s Head Area. By means of visual approach combined with monitoring, for Taiwanese visitors, it is estimated that social recreational carrying capacity of Candleholder Rock Area is about 4266 visitors and 5294 in Queen’s Head Area during a single day in spring; 3419 visitors in Candleholder Rock Area and 3800 in Queen’s Head Area during a single day in Summer; 4082 visitors in Candleholder Rock Area and 4634 in Queen’s Head Area during a single day in Autumn; 4282 visitors in Candleholder Rock Area and 3778 in Queen’s Head Area during a single day in Winter. For Korean visitors, it is estimated that social recreational carrying capacity of Candleholder Rock Area is about 5505 visitors and 6353 in Queen’s Head Area during a single day in spring; 4412 visitors in Candleholder Rock Area and 4560 in Queen’s Head Area during a single day in Summer; 5267 visitors in Candleholder Rock Area and 5561 in Queen’s Head Area during a single day in Autumn; 5526 visitors in Candleholder Rock Area and 4534 in Queen’s Head Area during a single day in Winter.

The main purpose of this study is to develop a carrying capacity’s process for eco-tourism. Base on the concept of sustainable development, we concern carrying ca-pacity component (physical-ecological, socio-demographic and political-economic) at the same time and try to develop these three types of indicators. Through the literature review, we develop a ten-step process and collect 36 indicators from related literature. In spite of using importance analysis survey to experts, we have condition survey of carrying capacity indicators and the survey of level of acceptable change to experts, residents and tourists. Then the study performs a case study to illustrate the application and the utility of the process and indicators for evaluating the status of tourism in Taomi. As a result, experts have more positive aspect to the current development. There is no indicator over its carrying ability or deterioration. However, the residents and tourists are more sensitive to the deterioration of overall environment. Besides, experts, resi-dents and tourists consider “increase rates of using private transport ”and ”increase number of tourists” have obvious deterioration and these two indicators are the most critical indicators. They can accept the deterioration at present. However, if those condi-tions go worse, they may over their upper limit and become the bottleneck of develop-ment of Taomi. As a conclusion, experts, residents and tourists can accept the change of the condition and they don’t think that the deterioration of carrying capacity condition is severe. This study can evaluate the attitude of experts, residents and tourists to Taomi’s carrying capacity condition. To compare with past studies, this process can completely cover the entire carrying capacity component.

The Kaoping River basin is the largest and the most intensively used river basin in Taiwan. It is 171-km long, drains a catchment of more than 3,250 km2. Based on the current water quality analysis, the Kaoping River is heavily polluted. Concern about the deteriorating condition of the river led the Government of Taiwan to amend the relevance legislations and strengthen the enforcement of the discharge regulations to effectively manage the river and control the pollution. Investigation results demonstrate that both point and non-point source pollutants are now the causes of biochemical oxygen demand (BOD), nutrients, and pathogens in the river. The main water pollution sources are livestock wastewater from hog farms, municipal wastewater, industrial wastewater, non-point source (NPS) pollutants from agricultural areas, and leachate from riverbank landfills. The current daily BOD, NH3-N, and TP loadings to Kaoping River are 74,700, 39,400, and 5,100 kg, respectively. However, the calculated BOD, NH3-N, and TP carrying capacities are 27,700, 4,200, and 600 kg per day. To protect public health and improve the river water quality, the comprehensive management and construction strategy is proposed. The proposed strategy includes the following measures to meet the calculated river carrying capacity: (1) hog ban in the entire Kaoping River basin, (2) sewer system construction to achieve 30% of connection in the basin within 10 years, (3) removal of 10 riverbank landfills, and (4) enforcement of the industrial wastewater discharge standards. After the implementation of the proposed measures, the water quality should be significantly improved and the BOD and nutrient loadings can be reduced to below the calculated carrying capacities.

Objective: This study investigated the effects of hand condition and carrying range on maximum acceptable weight of carrying through the psychophysical approach. Background: Manual materials handling (MMH) that causes lower back pain and musculoskeletal damage has been confirmed to be one of the sources that lead to industrial losses. Most past researches on MMH carrying tasks discuss two-handed carrying ,while studies on one-handed carrying remain scarce. Method: A total of 15 male participants were recruited to take part in the experiment. Under the assumption that work continued for one hour and with eight condition combination, including hand condition (one hand, two hands), and carrying range (F-F, FK, K-F, K-K), the participants used psychophysical approach to determine the maximum acceptable weight of carrying (MAWC), heart rate (HR), and rating of perceived exertion (RPE). Results: (1) The hand condition showed significant effects on MAWC, ΔHR, overall RPE, wrist RPE, arm RPE, shoulder RPE, back RPE , and whole-body RPE. The MAWC of one hand accounted for about 70% that of two hands. The ΔHR and the overall RPE of one hand were both higher than those of two hands;(2) The carrying range showed significant effects on MAWC,ΔHR, overall RPE, wrist RPE, arm RPE, shoulder RPE, back RPE, and whole-body RPE . The MAWCs ranked in order are: K-K, K-F, F-K, and F-F. Both ΔHR and RPE ranked in order are F-F、F-K、K-F、K-K;(3) The hand condition and carrying range showed significant interaction on MAWC and overall RPE. The best carrying combination is K-K carrying range with two hands and which produced the highest MAWC and the lowest overall RPE; (4) Finally, ten predictive models were set up in this study, with Model 8 inertial dynamic strength prediction model (R2=0.7766,PRESS=608) being the most practical. Conclusion: On the whole, the combination of K-K carrying range with two hands produced the best carrying capacity. Under the condition of one hand, the carrying range of K-K was the best. In addition, the predictive models set up in this study are intended for use during personnel screening. Keywords: manual materials handling, combined carrying tasks, hand condition, carrying range.

Objective: This study applied the psychophysical method to evaluate the effect of hand condition on maximal acceptable weight of carrying (MAWC). Background: It is well known that carrying tasks have quite extensive applications in MMH. Lower back pain and musculoskeletal injury caused by manual material handling (MMH) have been confirmed as the main causes of financial losses for companies. The most of previous studies regarding with hand condition focused on carrying tasks, without lifting and lowering activities, but researches on combined carrying tasks, with lifting and lowering activities, remain scarce. Method: Fifteen male students from Huafan University were recruited as participants in the experiments. The psychophysical method was applied to determine the maximal acceptable weights of carrying (MAWCs) for the six combinations of hand conditions (one-hand and two-hands) and carrying frequency (1 carrying/5 min, 1 carrying/min, 6 carryings/min) as one-hour working time. Meanwhile, the participants’ heart rate was measured. And the participants were requested to fill out the rating of perceived exertion, RPE, of seven different body parts, finger, wrist, arm, shoulder, back, leg and whole body, at the end of each experiment. Results: (1) The hand condition has significant effect on MAWC, heart rate, back RPE, and whole-body RPE. The MAWC of one-hand (14.6kg) is about 77% of two-hands (18.73). The heart rate and RPE of fingers, wrist, arm, shoulder, back, leg, and whole body, are higher for two hands compared to one hand; (2) The carrying frequency significantly influence on MAWC and RPE of each body part. The greatest MAWC appears at 1 carrying/5 min, followed by 1carrying/min, the smallest MAWC appears at 6 carryings/min, the significant difference in MAWC are among the three carrying frequency. Each body part has the greatest RPE at 6 carryings/min followed by 1carrying/min, the smallest is at 1 carrying/5 min; (3) Hand condition and carrying frequency has significant interaction on heart rate. The higher the carrying frequency, the higher heart rate is. The heart rate of two-hands is higher than that of one hand. At 6 carryings/min, the heart rate of two-hands is obviously higher than that of one hand; (4) The MAWC predictive model with single predictor, inertia dynamic muscle strength, ( R2=0.7516 ) is the most convenient model for user to predict the MAWC for different carrying tasks. MAWC= 1.4602 +4.8332H2 -10.24F1 -4.5376F2 +0.3572T1 Conclusion: The best combination of hand condition and carrying frequency for carrying tasks should be with higher performance and induce lower physiological load. When the carrying frequencies is 1 carrying/5 min or1 carrying/min, using both hands to carry is recommended. The high carrying frequency, 6 carryings/min, is not recommended since it induces heavy physiological load. Keywords: manual material handling, combined carrying tasks, hand condition, carrying frequency

The ecosystem of the Earth provides resource and environment for human beings to live and development. Resource and environment are limited in the Earth. The quantity of population and their activities are limited. In order to attain sustainable development for human beings, the activities of people must be limited under the carrying capacity of the Earth. Because of the influence by elements and interactions in the ecosystem of the Earth, the carrying capacity of the Earth is the main constraint to sustainable development for human. Base on ecosystem''s thinking, this study developed a method to evaluate the carrying capacity for a river basin and offered the related information to the decision-maker. For evaluated thecarrying capacity for a river basin, this study defined the definition of the carrying capacity at first. Secondly this study explicated ecosystem''s framework. Thirdly this study used D-S-R (Driving force-State- Response) construction to develop the evaluative method. Finally, this study built an evaluative model and an evaluative program to evaluate the carrying capacity for river basin. After the program evaluated, this study could get the carrying capacity for a river basin and the land-use type of the whole watershed at the same time. This study used the model to evaluate Chung-Kang River. The carrying capacity of Chung-Kang River was about 111,159 population equivalents in the present development based on some assumptions. The carrying capacity of Chung-Kang River would be increased about 30% when the land-use type of the river basin could be changed on ten percents allocation rates. In addition, industrial waste minimization of industrial process would increase the carrying capacity of Chung-Kang River also.

The purpose of this paper is to give references to management departments on tourists’ impressions of the capacity and crowding perceptions at the Yushan National Park, and the research areas included in this report include: Tataka Recreational Area, Meishan Recreational Area and Nanan Recreational Area. The result of study shows that crowding perceptions in the Yushan National Park is relative to the rubbish amount of the pavement and noise mainly, and to the infrastructure as like the parking stall , garbage bins , lavatory ,etc.. Besides, it is also correlated with the improper-act of scribbling , plucking and picking the flowers ,plants and trees wantonly, catching or feeding animals , destroying or defiling the communal facilities,and so on. The results of carrying capacity in this research are as follows: 1. Based on 224 respondents - Tataka Recreational Area should be limited to 1,120 people per day. The recreational facilities are rated to support 1,766. 2. Based on 65 respondents - Meishan Recreational Area should be limited to 325 people per day. The facilities are rated to support 605. 3. Based on 95 respondents - Nanan Recreational Area should be limited to 475 people per day. The recreational facilities are rated to support only 229. The suggestion in regulations of carrying capacity is include tactics of dispersing ,tactics of restraining, to adopt making the way of quantity by the difference priceing , the education of exposition and to increase the durability of resources ,etc..

Carrying capacity was a concept of operation and management, which initially used to investigate the numbers of community that the environment could support, later extended to outdoor recreation studies and formed “Recreational carrying capacity”. Recreational carrying capacity focus on the environmental and social impact of recreation use, and through limiting the number of visitors to maintain the recreational sustainable development. However, present studies of recreational carrying capacity in Taiwan put emphasis on the perception of visitors more than the other aspects. Gaomei Wetland, which is famous for its well-preserved habitats, become one of the most well-known and popular coastal wetlands in Taiwan. However, the growing number of the tourist has not only made Gaomei Wetland overcrowded, but caused harm to the environment. The main purpose of this study is to research the recreational carrying capacity of the wooden trail in Gaomei Wetland. By means of assessing the physical carrying capacity based on the area of the trail, the facility carrying capacity by counting the amounts of parking spaces, and using visual approach to quantify visitors’ experience for evaluting the social carrying capacity respectively. As a result, the suitable numbers of visitors should be 6,800 arrivals a day, however, considering that the visitors are not equally distributed in one day, we suggest that the recreational carrying capacity of the wooden trail should be limited to 600 arrivals per unit of time. The results of this study could help the local government restrain the number of the tourists in Gaomei Wetland to maintain the environmental sustainability.

Full textO aumento da atividade turística a nível global tem levado à superlotação, causando danos aos ecossistemas locais e degradação da experiência turística. Para planear a atividade turística é necessário definir indicadores adequados e entender as dinâmicas das multidões turísticas. Os principais objetivos desta dissertação são o desenvolvimento de (1) um algoritmo para avaliar a capacidade de carga física (CCF) de fino grão espacial para uma malha urbana complexa, (2) um modelo de simulação baseado em agentes para o escoamento de participantes em eventos de atração turística em espaços abertos e (3) um modelo de simulação baseado em agentes usando o algoritmo de CCF para análise do stress de aglomeração de turistas em cenários de malha urbana restritiva. Os dados abertos do OpenStreetMap foram usados nesta investigação. O algoritmo CCF proposto foi testado na freguesia de Santa Maria Maior, em Lisboa, que tem uma malha urbana antiga e complexo. A plataforma GAMA baseada em agentes foi usada nos dois estudos de simulação. O primeiro comparou dois cenários (normal e COVID-19) em três grandes espaços públicos de Lisboa e o segundo analisou o stress de aglomeração causado pela chegada de navios ao Terminal de Cruzeiros de Lisboa. Os resultados mostram a viabilidade do algoritmo proposto para determinar a CCF de zonas com tecidos urbanos complexos e a sua aplicação como valor de referência inicial para a avaliação do stress de superlotação em tempo real, nomeadamente na avaliação de cenários de aglomeração turística excessiva, tanto em espaços abertos, como em malhas urbanas intrincadas.

Abstract The purpose of this study is to investigate the social carrying capacity and emotional experience of visitors in the historical streetscape, also provide the management application for relevant organization as a reference. First, a review of pertinent literature regarding the social carrying capacity, emotional experience, assessments of dynamic landscape on the road and landscape visual simulation was carried out in order to establish the basis of the research theory. In this study, Pu-tou Street in Lu-gang and Yan-ping Street in An-ping are set as research section, which are representative of historical street area in Taiwan. The research tools are designed to carry out the computer dynamic simulation of these two streets to facilitate research. And then the research structure and the hypothesis were established in accordance with social carrying capacity and emotional experiences – related theories and studies. In previous study it reveals the index of perceived crowding of social carrying capacity in Pu-tou Street in Lu-gang and Yan-ping Street in An-ping. Both the uncrowded perception lies below the number of 15 persons; In Pu-tou Street the moderate perception lies between 16 and 40 persons and in Yan-ping Street it lies between 16 and 60 persons; The crowded perception in Pu-tou Street lies above 41 persons and in Yan-ping Street it lies above 61 persons. Hence the perceived crowding of visitors in Pu-tou Street is stronger than in Yan-ping Street. The result of research regarding the emotional experience of visitors to historical streetscape can be described by the following two basic categories: “Pleasant – Leisurely” and “Tranquil – Peaceful”. The feeling of “Pleasant – Leisurely” was strong emotional reaction and “Tranquil – Peaceful” was weak. Combining the analysis of this study, when the visitor tour around historical streets and contact other visitors, it revealed the index of perceived crowding of social carrying capacity is related to the emotional experience in historical streetscape. And the index of perceived crowding will affect the emotional experience of visitors that lay the apparent distinction according to the different historical streetscape.

To live or develop sustainably, people must utilize resources sustinably.And the term carrying capacity is just the judgement whether resources wereutilized sustainably or not. i.e The amount of resources consumed must notbe great than that of environment could carry. This study was based on sustainable development indicators to choose onesrelated to water environment carrying capacity that defined as influenced by watr quality, water consumption and land-use. The above chosen indicators werelimitations that evaluate to compare the above chosen indicators. For developingsustainably in any river basin, we should try to promote the capacity to a satisfied level if the real population of a river basin is great than the population equivalent calculated by the above method. In our case study, we only consider the following five aspects: the classifiedwater quality standard of water body, municipal water conumption, industrialwater consumption, the rate of an uptown- commercial area to total area, the rateof an industrial area to total area, the non-forest areas, and the divided numbers of the changeable area. The final results show that the industrial waterconsumption and the rate of an industrial area to total area influence the population equivalent significantly, others are not.

In bridge architecture, the arch mechanism of arch bridges and the mechanism of suspension bridges and cable-stayed bridges use beam-column member (which are molded from many thin plates) as a structural base material. The axle and bending integrity of these materials are regulated by the Ministry of Transportation and Communication under the Transportation and Bridge Architecture Regulations, yet they didn’t provide a way to calculate the integrity of the materials to meet their standards. This research tested the axle strength, bending integrity, and the integrity of both combined using the finite element method. Starting with the design and development of longitudinal stiffened strip and the design and development of diaphragm’ Box column , and then testing both with the program sap2000. The data collected was then further calculated, compared, and analyzed. The results of the research displayed that the data from regulations surpassed those using the finite element method. But if effective measures are taken in the cross-section outside , then the buckling strength with increase greatly.

Accurate estimation of carrying capacity of an air basin is essential to the successful application of allowable emission control strategy. The way to understand the feasibility of the control strategy is to apply dispersionmodels to simulate the air quality. In order to compare the impact from point,mobile and area sources on the air quality in central Taiwan, dispersion modelsare used to find the allowable emission rate in this area. The modes used areISC3 and UAM. Rollback method and environment allowable capacity methods areused to estimate the carrying capacity in this area. The difference betweenthese two is also studied. Two methods are used to estimate the carrying capacity - Rollback andenvironment allowable capacity. Rollback assumed that there is a linear relationship between emission amount and air quality. The essence of rollbackis "less emission and better air quality". Environment allowable capacity is similar to total allowable emission policy in that there is an upper limit for emission. The allowable emission is not fixed but varies with weather condition. Based on this, the carrying capacity of this area is 24,372 ton annually. And the daily allowable emissions are 41 - 264 ton. The execution process of model- UAM is listed in the appendix of this report.
