Abstract: Transit network design as the first and critical phase of public transportation planning is extremely sensitive to transit demand. An important characteristic of transit demand is elasticity or service-dependency, which means that any change in the service offered by the system is followed by a change in transit demand. Due to the complexity of transit network design problem (TNDP) researchers have usually assumed transit demand to be fixed rather than elastic; while ignoring this issue may result in inefficiency of system, dissatisfaction of users, and system failure, since the predicted amount of passengers would not use the transit system. This paper aims to demonstrate the necessity of elastic demand consideration in transit network design, and proposes a solution framework, which is composed of a preparation stage and an iterative procedure. A case study example is presented subsequently, to show the use of this solution method and further illustrates the necessity of considering this issue. Three cases of truly predicted demand (considering elastic demand), overestimated and underestimated demands (in the absence of elastic demand consideration) are defined, and the performance measures of these cases are compared to those in the base mode. The results show that elastic demand consideration leads to the optimal network, in which the system efficiently matches between supply and demand.

Abstract: Based on the analysis of the status quo of Kunming urban traffic, Kunming's urban public system reveals problems with development of Kunming, put forward some countermeasures which solving traffic problems in Kunming.

Abstract: Along with social economy's swift development, the urbanization and the motorization advancement also speed up along with it, and brought the huge challenge for the municipal transportation. The altitude systematic characteristic is not only the municipal transportation bright characteristic, but also the substantial clause which transportation domain many questions difficulty with govern. The municipal transportation sustainable development question has become the key point and the difficult question of domestic and foreign sustainable development domain. This paper through the transportation plan and the urban planning interaction development, gives priority to the urban mass transit, the implementation transportation requirements management, optimizes the municipal transportation network, realizes the sustainable development, thus establishes the urban low-carbon transportation system.

Abstract: Mass Transit is the transportation for tomorrow. Mass transit is able to commute a large amount of people in a certain period of time with a pre-designed controlled speed. This paper intent to pervail the importance of mass transit as the only earth- and user- friendly public transport, as well as the most important urban tourist transport in the near future. Ideally, the tourist should be able to visit all destinations within a city with mass transit which integrated with walking and cycling to create a wonderful travel experience.

Abstract: Abstract. Due to the analysis of prevalent problems of out urban transportation and the reasons, this essay will illustrate the meaning of green transportation and the strategies and actions for the realization of that objective, pointing out the development direction for urban transportation in the near future.

Abstract: This paper presents an approach to calculate PA matrix of transit trip from passenger flow volume. This approach is based on inverse calculation of distribution matrix by observing traffic flow and the characteristics of public transit planning in practical investigation is taken into account. It also suggests the method to test the accuracy of final matrix.

Abstract: The urban rail based Transit Joint Development (TJD) has become one of the most important financing channels for constructing urban rail transit systems in China. Compared to the extensive research and application in planning field, the implementation of TJD still faced some difficulties such as organizational model selection, distribution of benefits and so on. In the 1980s and 1990s, the United States, Japan and Hong Kong developed a series of TJD practices and they formed three kinds of TJD mode: Public-Private Partnership, Enterprise Oriented, and Franchise. Empirical evidences have shown that differences among three modes are mainly reflected in the selection of implementation agency, allocation of functions and distribution of benefits. Then these distinctions will cause various impacts on the scale, cycle, form and operational management of TJDs. The conclusions of this research could provide valuable experience to the ongoing work of TJD in Chinese mega cities.

Abstract: Nowadays, delays problem are important issue in preparing schedule for public transportation. It is related to behaviour of passengers, behaviour of transportation means and interaction with traffic. Behaviour of passengers are including: demand patterns of passengers, fare payment and waiting time in station and in-vehicle. Behaviour of transportation means included fleet size and frequency of operation. The most interaction between public transportation and others traffic is in traffic congestion. In this paper, we studies different behaviour of passengers duration operation time in two points: in-station and in-vehicle. They are including: arrival rate of passengers, kinds of fare payment and waiting time. For illustrate behaviour of passengers on delays problem we survey they affects in bus operation. Hence, a case study based on an actual public bus operation in Tehran, Iran is used to demonstrate it.

Abstract: At present, the fragmented development of urban and suburban bus system is facing many problems and difficult to adapt to the requirements of urban-rural integration in China. In this paper, the urban and suburban bus route network and passenger volume distribution characteristics were analyzed, the operational efficiency of the two system was compared based on the case study of Weihai; the principal factors that influence the operational efficiency were further studied; and finally, the integration plan of urban-suburban bus system as well as the suggestions on its implementation were proposed.

Abstract: In order to reduce traffic accidents, achieving safety and harmony of traffic color, a quantitative research on traffic color of urban road were carried. Grounded on modern knowledge of color theory, color psychology, Grey Theory and Back-error Propagation Artificial Neural Network (GT-BPNN), Particle Swarm Optimization algorithm (PSO) and traffic questionnaires, the evaluation index system of traffic color in urban road, the evaluation model of transportation color and the model of color harmony and optimization in urban road were constructed. Assisted by MATLAB and other software, the reliability and validity of models were determined, taking a road in Xuzhou, Jiangsu as a test section. According to the results, some reasonable improvements on traffic safe color were recommended.
