The public transport infrastructure of a city is one of the most important indicators of its economic growth and development. Here we study the public transport network of Shenyang, which represents Chinese domestic civil public transport infrastructure, as a complex network. We find that the public transport system of Shenyang, a network of public transportation routes connected by bus links, is a small-world network characterized by a Poisson degree distribution. We investigate the public transport network as a complex network to explore its topological properties. Simulation results show that the public transport network exhibits small world behavior.

Abstract This article presents a detailed description and explanation of the methodology for evaluation of quality public transport criteria in terms of passenger satisfaction. In 2011-2014 this method was applied in an assessment of passenger satisfaction with the urban public transport system in Ostrava. In order to assess passengers’ satisfaction, traffic survey has been chosen utilizing questionnaire and student inquirers. The results achieved by application of the method have been processed to evaluate time accessibility criteria of a public transport system. Time accessibility criteria group (accessibility of stops, waiting for a connection and transferability in the public transport network) evaluates physical and psychological aspects of the passenger during his arrival at the station, while leaving the station, in the course of waiting for a connection and during the transfer. The time accessibility criteria are considered the most significant criteria that impact a passenger’s decision to utilise public transport options.

Public transport transforms urban communities and the lives of citizens living in them by stimulating economic growth, promoting sustainable lifestyles and providing a greater quality of life. Globally, the healthiest cities have one thing in common, a public and active transport network that does not depend on each person owning a personal motorised vehicle. Growing dependence on the automobile has created a multitude of problems, some of which public transport can help solve. Adverse social, environmental and health effects related to automobile emissions and car-dependency suggest that using public transport will result in a decrease in an individual’s carbon footprint, will lessen overall CO2 emissions, and will help to ease urban traffic congestion as well as encourage more effective and efficient land use. With many urban areas experiencing ongoing traffic problems, it is acknowledged that any sustainable long-term solution must entail a significant public transport element. The aim of this research study, conducted in November and December 2017, was to obtain essential baseline information on service user satisfaction levels with the existing public bus services in Galway City, Ireland. By measuring levels of satisfaction, it is possible to build our overall knowledge of the public transport network and thus identify improvements in the service that would lead to an increase in bus passenger numbers and result in reductions in the amount of cars on the roads. Results suggest deficiencies in public transport infrastructure, such as Dedicated Bus Lanes, and the lack of attention to customer services are hindering improvements in the public bus service.

The public transport network level is defined and is used to describe the performance and future improvement of the public transport system in Zurich, Switzerland. A public transport level is a specific type of service designed to serve a particular market. “Service” is defined as a combination of vehicles, infrastructure, and operating characteristics. A pure level occurs when the service is targeted specifically at one particular market. A hybrid level occurs when a service is targeted to serve several markets. Urban travel is generally described as three markets: short, inter mediate, and long-distance trips. Consequently many cities have developed three-level public transport networks: surface buses and trams to serve short trips, rapid rail to serve intermediate trips, and regional rail to serve longer-distance trips. Often, by design or for historic reasons, cities have additional levels, fewer levels, levels that are not precisely matched to their markets, or all three. For example, two-level networks are often found in medium-sized cities. Their advantage is lower costs, and their main disadvantage is a mismatch between transport mode and market that manifests itself in capacity limitations. The level concept to help analyze and plan public transport service is useful because it focuses attention on matching service qualities to markets. This approach, used here to analyze the success of the public transport system of Zurich, Switzerland, and to provide a structure for planning improvements that will be needed to meet rapidly increasing public transport demand, could help other cities design or redesign their public transport systems to be more attractive and efficient. More specifically, the approach could show how two-level public transport networks would be a viable option for medium-sized cities and large cities with dispersed settlement patterns.

The present paper aims to be useful for public transport operators and municipalities, as it should enable them to make decisions and to optimize public transport schedules during peak hours. In this study, we outline the data and the means necessary for the creation and use of a specific database for a dynamic spatial analysis of the public transportation network. This will facilitate the analysis of public transport vehicle operating programs and the simulation of new transport programs using open-source software. This paper delivers the first digital map of the public transport in Bucharest. Using the QGIS software and the PostgresSQL database, (i) we analyzed the accessibility of public transport stops for residential areas (5-min isochrones, corresponding to walking distances of 400 m), and (ii) we determined the correlation of transport vehicle programs with the existing transport network to optimize the headway of vehicles. These two elements were considered for the analysis of public transport performance. The research study was based on the tram network in Bucharest, but it can be easily upscaled for the entire public transport network and may be replicated in other large cities.

AbstractTransport-based social exclusion is currently a serious social problem in Poland, and one which is apparently most severe at the level of the county (Polish powiat) in the south-east of the country, including the Beskid Niski and Bieszczady Mountains. A deeper illustration of this problem requires both observation of changes in the suburban public-transport network and the identification of areas in which this has deteriorated significantly in quantity and quality. The chosen starting point for the research was therefore 1990, as a year in which — on the one hand — the Polish economy was already shifted to the new free-market principles; while — on the other — state PKS (Przedsiębiorstwo Komunikacji Samochodowej) non-urban bus transport enterprises still dominated public transport. The endpoint of the study is then the beginning of 2019 (the author’s research year). The article introduced here seeks to identify and present cartographically the changes affecting the public-transport network in the study area over the last 30 years, as well as to point to possible consequences of these processes. The background of the described changes is also discussed, as are the observed consequences of what is taking place.

Briefly introduced Chinese urban transportation status and future trends, proposed should vigorously develop public transport, to establish a perfection and diversified urban transport network. Combined with the characteristics of ropeway, analyzed cableway should play a role in the public transport network, discussed the feasibility of building a cableway at five special area in urban.
