Nowadays, the total volume of passenger trip demand has increased due to population and economic growth. In this situation, government policy encourages people to use public transportation for inter-city trips. In the meantime, buses are the most widely used in transit technology today. The most important issue in buses service is timely arrival. Due to the limited capacity of the streets and increasing car production, we cannot devote a specific lane to bus operation to separate their operation from other traffic. Generally, actual arrival time of buses in comparison to planned arrival time occurs in three scenarios: sooner, on-time, and later. This article represents different scheduling model to achieve timely arrival. For this purpose we tested two different scenarios by actual public bus operation. The data was obtained in the city of Tehran, since Iran was used in this study. © (2011) Trans Tech Publications.

In bus networks there are many stations used for boarding and alighting passengers along the bus route. In designing bus stop location three sides approach to be considered; the big picture, street side and curb side. Apiece of three sides have directly affects in the bus scheduling. The effectiveness of bus operation will depend on number of bus stops and its spacing. Basically, bus stations have two kinds: bus stop, use to service passengers in one bus line and bus interchange (terminal) use to share station between some bus lines. This article described a survey on bus stop location efficiency in bus operation where study on bus stop location in three points: near-side, far-side and mid-block were considered. It has been highlighted bus stop location in situation mid-block has higher efficiency than others situations. © (2011) Trans Tech Publications.

Bus networks occupy less space in city streets, and compared to other kinds of public transportation, need less investment cost. An accurate bus operation schedule which considers actual arriving and departure time is essential for bus companies, due to high passenger demand. In real-world cases, there are daily differences in the frequency of bus dispatch from the terminal, and headway of buses between each bus bay along their route, depending on peak hour traffic and resulting congestion. In this research we studied effective parameters for preparation of proper bus operation scheduling. Measures are essential to ensure that buses receive priority over other traffic, if they are to be attractive to passengers. Finally, we suggest some solutions for lessening interval time in headway and frequency scheduling for bus services. Data obtained from an actual bus operation in the city of Tehran in Iran was used in this study. © (2011) Trans Tech Publications.

The major western cities of China are beginning to suffer the growing traffic congestion problems, which eastern cities of China has experienced. Learn lessons from eastern cities on traffic issues as soon as possible, dealing with the diversified modes of public transportation problem of convergence effectively, providing condition for integration development of urban public transport in the west is the main goal in this paper. This paper takes Subway transit Line 6 in Chongqing as a bus connection example. On the basis of passenger volume forecast, integrated public transport optimization theory and method are used to study Chongqing subway transit Line 6 along the feeder site optimization program, it can provide the theoretical foundation and technical support for the public transport network optimization of Chongqing. © (2013) Trans Tech Publications, Switzerland.

As major cities in China entered the era of urban rail transit, the integration of multi-modal public transport has become the inevitable way to improve public transport attractiveness. This study carried out technical and economic characteristics of two public transport modes,whichwere used for functional positioning. A bus network optimization method from point to line then to surface was proposed, and different types of feeder station layout form and scale were determined. Existing bus line network adjustment method is based on spatial relationship and passenger travel cost. In the new feeder bus line layout optimization process, with minimizing the total travel time of passengers as the planning objective, a feeder efficiency model was built. Last but not least, the example of subway line 1 in a city was used as a case study; by analyzing the status of the bus operation along subway line 1, suggestions were given on bus network optimization. © 2014 Taylor & Francis Group.

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. © (2011) Trans Tech Publications.

This paper has introduced the TOD mode into the optimization design of all levels of urban public transport hubs, and probed TOD mode that effectively combines land use and urban public transport hubs. A TOD planning model for the land use of urban public transport hub was built by means of a multiple objective mathematical programming model. Four objectives were considered: to increase the express public transport capacity, to improve the environment of the planned region, to maximize the returns on investment, to ensure the balance of mixed land use. The model can be used for designing the rate of public transport hub area. The Shisheng public station area in Wuhan is chosen as case study to illustrate the model application and planning results. The result indicates that the model would be efficient in practice. © (2014) Trans Tech Publications, Switzerland.

Urban transport database (UTD) is one of the most important bases for academic research and management in transport sector. In this paper, comparison analysis between international and domestic urban transport database was implemented. Based on the Chinese practices, the objectives, framework and key technologies of the Urban Transport Database were presented. The upload and download mechanism of the urban transport data was presented as well. It will provide an efficient technical support for UTD construction in China. © (2011) Trans Tech Publications.

The relationship between tourism traffic and tourism development are closely, especially the road condition of mountainous area is complex and the traffic characteristics is diversity. Study on tourism traffic character in mountain area during vacation not only can forecast the change trend of tourism traffic in advance but also can resolve some traffic safety problems during vacation. The paper takes the scenic area Yesanpo in Hebei province the basic point of investigation. We selected typical sections, Collected related data by using the method of manual counting and the traffic data acquisition instrument Metrocount 5600. Done Tourism traffic character analysis in mountain area during vacation by statistical methods, including the traffic characteristics of major sections and traffic source, velocity distribution etc. This study provides a reference for future mountain tourism traffic organization. © 2012 IEEE.

In the paper, the indicator system and evaluation methodology of BRT operation was established according to the characters of BRT development in China. These indicators include six aspects: infrastructure, transport capacity, service level, economic results, safety and emergency management, and energy saving & emission reduction. The pilot study was implemented in Jinan city. The results of pilot study show: the presented evaluation methodology of BRT operation agrees with the system designing standards and therefore is operational. © 2005 - 2013 JATIT & LLS.
