Public Transportation System

The spatial and economic growth of cities and regions is heavily influenced by transportation. A better knowledge of public transportation will help to clarify the positions of the public and private sectors, as well as recognize the critical government position. To study the problems and issues of the public transportation system, Qasimabad, Hyderabad is selected as a study area due to some serious issues of public transportation. Personal observations and questionnaires were used to gather data from the research area. And for analyzing the data SPSS and MS Excel are used. The results reveal that the existing public transportation system is not meeting the needs of residents. Hence use of private transportation is high and causing environmental and traffic jam problems. As 68% of respondents use a motorbike for recreational purposes, 64% of respondents are not using public transport due to safety factors. In general, 54% of respondents were not satisfied with the service of public transport. As people are willing to use public transport but due to some factors such as safety, they are not using public transport so it is suggested that both vehicles and roads must be safe for users. This study aims to study the existing scenario of public transportation in terms of services and facilities, and people’s perception about public transportation. So it is concluded that people are tending to use public transport but under some certain conditions (factors preventing the use of public transport), if these concerns are solved then public transport system will become more efficient.

Abstract With the rise of the sharing economy and the concept of “green environmental protection and low-carbon travel”, the emerging project of shared electric vehicles is booming. However, the accompanying coordination problem between shared electric vehicles and public transportation system needs to be urgently solved. In reality, customers’ choice of travel mode is influenced by their own travel perceived utility. Thus, this paper will discuss the competition and coordination problem between shared electric vehicles and public transportation system from the perspective of customer travel utility. Considering the travel cost and comfort in the customer travel utility, the game models of shared electric vehicle and public transport system in different scenarios are established by using competitive game and cooperative game. Then, the equilibrium solutions under different scenarios are obtained by solving the models. The analysis results show that shared electric vehicles would bring some beneficial improvements to the transportation system under certain circumstances. Furthermore, public transportation system should adopt a coordination strategy with the shared electric vehicles to promote the total customer travel utility for the entire system. It is worth considering the improvement of the service quality of shared electric vehicle and public transportation next, which would affect the rate of increasing in the total customer travel utility.

Speed Up

There is a large number of tools for the simulation of traffic and routes in public transport systems. These use different simulation models (macroscopic, microscopic, and mesoscopic). Unfortunately, these simulation tools are limited when simulating a complete public transport system, which includes all its buses and routes (up to 270 for the London Underground). The processing times for these type of simulations increase in an unmanageable way since all the relevant variables that are required to simulate consistently and reliably the system behavior must be included. In this paper, we present a new simulation model for public transport routes’ simulation called Masivo. It runs the public transport stops’ operations in OpenCL work items concurrently, using a multi-core high performance platform. The performance results of Masivo show a speed-up factor of 10.2 compared with the simulator model running with one compute unit and a speed-up factor of 278 times faster than the validation simulator. The real-time factor achieved was 3050 times faster than the 10 h simulated duration, for a public transport system of 300 stops, 2400 buses, and 456,997 passengers.

Aiming to facilitate the choice of transport links leading from a starting location to a destination in greater Cairo, we propose in this work a public transportation mobile (android) application to assist users of public transport. The system is a pilot application that considers the public mini-buses network in three areas of Cairo, and builds the database of the mini-bus network verified on the ground. From this database, the transportation network graph consisting of nodes and possible links between them is constructed. Upon request, the system then identifies the series of public transport possible, calculates the shortest path between the two chosen locations, and displays the bus, or series of buses, and the routes to the user, ordered by distance. The specialized algorithm Dijkstra was implemented to find the shortest route.

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.

One aspect of Kuching City that has not progressed in tandem with the rest of the city is the public transport system, which is relatively old and almost non-existent. Transport and City planners seem to be at their wit’s end in coming up with satisfactory solutions to Kuching’s public transportation woes. In current situation, many proposals, but none have proven workable. As a result, representative buses remain a rare sight on Kuching city’s roads. To achieve a sustainable public transport industry, the old buses need to be regenerated and replaced with modern buses. The objectives of the intended study are to explore the consumer’s travel behaviour by employing mode choice modelling. Consequently, a study was conducted in Kuching City Area by using stated preference technique, analysed and compiled by using SPSS.17 multiple linear regressions analysis. In this context, discrete choice analysis was used to examine the relationship between independent variables (travel time, waiting time, fares and comfort) and dependent variables (choice of respondent whether to consume old bus or choose new bus services). A total of 2000 respondents were interviewed. The findings showed that for the trips purpose, fares and comfortability were the primary factors that reflected the decision or behaviour of the respondents asked. It was discovered that there is a significant relationship between the choice of the respondents and comfortability. It also appeared that longer travel time did not affect for the traveler’s choice at this stage. Hence, the study suggests that the local authority and the bus operators should establish a “quality partnership” and working together in order to come out with a much better and appropriate transport policy and schemes for the existing public transportation systems, especially bus services.

The increasing number of private vehicles shows that the public transportation system in Makassar has not been maximized. this is also due to the absence of other alternative public transportation modes that can be used by the community in their activities. This study aims to determine the preference of public modes of choice if offered other alternatives, especially public transport with greater capacity. Public transportation offered in this study is busway and monorail. In this study the community was faced with 3 modes of choice namely city transportation, monorail, and busway. The data collection method used was a survey with stated preference based questionnaires, which reviewed nine conditions for variable change in travel speed. The construction of the model was carried out using STATA software and city transportation was used as the base outcome. The model is based on discrete selection models and is analyzed by the multinomial logit model. The results showed that in the nine conditions of change in travel speed, the mode of city transportation was still more dominantly chosen by the community.

Abstract The long-distance public transport services among the eight regional centres of Slovakia, representing the key urban locations with concentrations of most of the country’s services, including business, educational and financial institutions, as well as political power, are examined in this article. It is assumed that the mutual transport interconnections within this group of cities will be a focus for public transport operators in their attempt to gain the largest possible share of potential customers, passengers who would otherwise be users of individual transport means. Hence, one of main aims of this study is to compare public and individual transport modes, and the possibilities offered by them in the mutual interconnections of major regional centres in the country
