BackgroundFor cities aiming to create a useful surveillance system for bicycle injuries, a common challenge is that city crash reporting is scattered, faulty or non-existent. We document some of the lessons we learnt in helping the city of Boston, Massachusetts, USA, do the following: (1) Create a prototype for a comprehensive police crash data set (2) Produce the city’s first cyclist safety report, (3) Make crash data available to the public and (4) Generate policy recommendations for both specific roadside improvements and for sustainable changes to the police department’s crash reporting database.MethodsWe provided research and technical assistance to government partners to generate the report and used participant-observation field notes to generate the list of learnt lessons.ResultsAfter the release of the report, the city implemented immediate activities aimed at making an effort to prevent injuries, including: (1) Furnishing over 1800 taxis with stickers to prevent ‘dooring,’ (2) Adding pavement markings at trolley tracks to decrease the likelihood that cyclists would fall from getting their wheels lodged in the tracks, (3) Conducting targeted enforcement of traffic laws and (4) Working directly with state and federal agencies to fund a more comprehensive surveillance system. As of January of 2017, nearly 4 years after its public release, 19 170 users have viewed the crash data set 23 247 times. Some of the lessons include finding and using committed champions, prioritising the use of existing data, creating opportunities to bridge divisions between stakeholders, partnering with local universities for assistance with advanced analytics and using deliverables, such as a cyclist safety report, to advocate for sustainability.ConclusionProviding an initial report on bicycle crashes in Boston served to identify specific problems, showed the value of a data system, and provided a blueprint for an improved data system. Building a useful surveillance system depends in no small part on the wise use of advocacy, group dynamics, and politics. Our hope is that the lessons learnt from our experience in Boston can help others do even better.

In this research project the author analyzes a most relevant problem, that is, biosphere compatibility of urban space planning in major megalopolises; this problem comprises the launch of a comfortable transport system, convenient transport routes free from any traffic jams in urban streets and highways. The author con-siders different methods for organization of convenient transport routes in Moscow. The author believes that a comfortable transport network is a main factor for sustainable development of the urban economy that may help the city to restore its main functions. The author has employed the retrospective analysis of the materials produced by the media, namely, news items published in Moscow and Moscow Metropolitan area in respect of the transport organization patterns. The author has also employed the method of historical comparisons, as well as the general scientific methods of deduction, induction, and deduction by analogy. The author collect-ed the source material by launching a questionnaire-based survey among the residents of the capital. The survey served to help the author to find out the main trends in the organization of the urban space and to identify the transport preferences of urban residents. Moscow transport development trends include broad-ened bus lanes, rent-a-bicycle stations, construction of hubs both on the outskirts of Moscow and in its cen-tre, and liquidation of traffic “bottlenecks”. Innovations include replacement of trolley bus and bus routes by electric bus routes. The retrospective analysis of e-transport networks in Europe and North America is of-fered to identify the current needs of European megalopolises. The survey findings can be invested into the organization of the Moscow transport network.

The basis of this article is the proposal to use bicycle rail trolleys as preventive measures before draisining the Dolina Bobru railway line. This tourist attraction can be promotion for the poviat of the Lwówek Śląski. This can help to reconstruction of the regular rail connection between Legnica-Złotoryja-Lwówek Śląski-Jelenia Góra.

Abstract In the EU programming period of 2014–2020, Hungary’s largest-ever transport development project, an intermodal passenger terminal (IPT), is planned to be built in Debrecen. The IPT will integrate all public transport modes operating in Debrecen in a single building, with the modes being as follows: railways, long-distance and local buses, trolley-buses and trams. In addition, by creating a large number of parking spaces for cars, and by building lanes for bicycles and pedestrians heading into the facility, the public transport and individual transport modes will be directly connected under the roof of the IPT. The IPT development will be accompanied by large-scale urban renewal projects to revitalise Petőfi square, one of Debrecen’s major public spaces, lying in front of the building. Relating to the IPT development, several feasibility studies and sustainability analyses have been performed; however, the impact of the IPT on the development of Debrecen has not previously been examined. The main goal of this paper is to examine whether IPT development contributes to the enhancement of Debrecen’s central position in its agglomeration, the strengthening of Debrecen’s competitiveness in Hungary’s urban system, the spatial decentralisation of the city’s cultural activities and how it may influence the change of Debrecen’s socio-economic factors.

The basic resistance during moving objects that are equipped with a circular system is rolling resistance. In objects powered by muscle power, such as: bicycles, wheelchairs, mobile machines, shelves and storage trolleys, the problem of rolling resistance limitation is more important than in the case of structures powered by engines characterized by a significant excess of driving force relative to the sum of resistance forces. Research is being carried out on limiting the rolling resistance force, however, there is a lack of methods for measuring this parameter in the actual operating conditions of devices with a drive system without a drive unit. In the article for research, an innovative method was used of measuring the rolling resistance coefficient of objects equipped only with the rolling chassis of accordance with the patent application P.424484 and a test device compatible with the patent application P.424483. The study involved a pneumatic wheel commonly used in wheelchairs, the use of which gains popularity with increased interest in the construction of electric or diesel vehicles with low energy demand. Examples of such vehicles are available during the Shell Eco-marathon competition. The study was financed from the means of the National Centre for Research and Development under LIDER VII programme, research project no. LIDER/7/0025/L-7/15/NCBR/2016.

Denna rapport behandlar ett projekt för examen inom programmet Högskoleingenjör inom innovationsteknik och design. Projektet genomfördes tillsammans med företaget Atran Velo med målet att utveckla en cykel-/dragvagn som ska integreras med företagets AVS-system. Projektet genomfördes under våren 2021 vid Karlstads universitet och omfattar 22,5 hp. Projektets syfte är att ta fram en vagn som ökar lastförmågan hos en standardcykel. Detta möjliggör att människor kan bruka sin cykel vid flera tillfällen, vilket bidrar till flera positiva aspekter. Genom att transportera sig med cykel i stället för bilen bidrar det till minskade utsläpp. Detta har en positiv påverkan på miljön och klimatet. Det ökar även den fysiska aktiviteten hos människan, vilket bidrar till att individens välmående ökar. Projektet har utgått från produktutvecklingsprocessen med faserna: projektplanering, förstudie, produktspecifikation, konceptgenerering, konceptval, konstruktion, slutprocess och rapportskrivning. I faserna har olika beprövade metoder används.  Projektet resulterade i ett konceptförslag på en vagn och koppling som företaget ska arbeta vidare med efter detta projekt. Vagnen fungerar som både en cykel- och dragvagn som enkelt går att koppla på och av cykeln med en AVS-adapter. Till exempel för att cykla förbi affären och använda vagnen för mathandling. Vagnen har två lastytor som har integrerade AVS-bryggor vilket gör vagnen till en AVS-bärare, med detta menas att vagnen kan användas med företagets olika tillbehör. Vagnen går även att vika ihop för platsbesparing i hemmet för att öka kundvärdet. Vagnen är tillverkad av aluminium för att minimera vikten på produkten och motstå korrosion.
This report deals with a project for a Bachelor of Science in innovation technology and design engineering degree at Karlstad University. The project was conducted on behalf of the company Atran velo. The goal of this project is to develop a bicycle/tractor that is integrated with the company´s AVS-system. The project was carried out during the spring 2021 and comprises 22,5 hp.  The purpose of this project is to develop a trolly that can increase the load capacity when using a standard bicycle. This allows people to use their bicycle on several occasions which contributes to many positive aspects. By taking the bicycle instead of the car it contributes to reduced emission, which has a positive effect on the environment. It can also increase the physical activity of people which contributes to the individual’s health.  The project has been based on the product development process with the phases project planning, pilot study, product specification, concept selection, design, final process, and report writing. In these phases various proven methods have been used.  The result of this project is a concept of a trolley with coupling. The trolley can be used both as a bicycle cart and carriage. It can easily be connected and disconnected from the bicycle, when for example doing grocery shopping. The trolley has two loading surfaces, and both are integrated with AVS - bridges which makes it work like an AVS-carrier. It can also be folded for space saving witch increase customer value. Most of the trolley is made of aluminum which minimize the weight and is corrosion resistance.
