This paper presents emergency events in the urban road traffic system caused by bus delays buses and consequent congestion problems. It intends to dissipate the traffic congestion of passenger transport network. For the purpose of keeping the order of transit passengers and improving efficiency of transit service, it is important that transit passengers obtain the travel information when transit service...
The path travel time between trips are proved to be strongly linear correlated, and the regression parameters are gradually converging to a steady value with buses travel on the route. A regression-based method for bus trajectory estimation at downstream stops was proposed, and its performance on estimation accuracy was compared with the historical-based model. The research results show that the proposed...
Dwell time is an important factor affecting the service capacity of bus route, but the limited capacity of bus stops may lead to the bunching problem which will cause longer dwell time for serving passengers, especially for the corridor with several collinear bus routes. In this paper, two groups of regression models for dwell time estimation were proposed to verify and calibrate the effects of bunching...
Based on the analysis of shortcomings of traditional statistics research methods, the characteristics of geostatistics and its applied fields and application principles are proposed to solve the traditional research method of statistics on the floating car speed without considering its spatial structure. Meanwhile, the spatial analysis model and the solving algorithm are presented. The spatial structure...
In this research, travelers' responses to transportation service according to their budgets on travel time, money, and energy expenditure are studied based on the analysis of intrinsic characteristics of transportation service and travelers. A new perspective of evaluating the route-level transit service quality, which is distinguished from that of network-level, is discussed with recommended system...
Public transportation system make a good sense to reduce the emission of Carbon Dioxide, and this study proposes a revised SERVQUAL-based method to evaluate urban bus service quality from passengers' point of view, which aimed to increase the ridership share by increasing the quality of this service. Two representative bus routes, Bei'an and Line 119, selected from Shanghai and Chengdu respectively...
This paper studied the characteristics of bus serving process, explored the way passengers cognize and perceive the bus service, as well as their response to information conditions. A multi agent based model was proposed for the purpose of simulating bus serving process and estimating performance of single-route bus service, which is described by an introduction of the simulation platform, SimCUBE...
The application of information technology makes it possible that transportation planning professional utilize mass detective data. The paper, according to business process reengineering theory, analyzes the effect of transportation planning operation process reengineering on transportation planning operation. The system in the paper is developed based on transportation software-VISUM, and integrates...
The relations of mutual limitation and transition between dynamic lane assignment and running time allocation at an approach of signal control intersection were studied and an optimization model-based on time-space resource combination was proposed in this paper. The numerical test results show that the method can give an optimum benefit scheme based on dynamic lane functional partition within a given...
Based on analyzing the past research on vehicle scheduling in transit scheduling, a new optimization model to minimize the total vehicle operation cost is proposed. This optimization model is a nonlinear integer programming and can be solved rapidly with the global solver in LINGO, as long as the appropriate value of fleet size. It is the advantage of the optimization model and solution methodology...
