Application of VISSIM in the public transportation priority signal timing;

Based on independent bus priority signal control planning and coordinated control theoretics in area, aims at minimum per capita delay at neighboring two intersectio.

For ensuring the efficiency of implementation of priority strategy, as an important method to achieve urban public transport priority Transit Signal Priority (TSP) plays an important role.

Germany, France and Switzerland have adopted, in some of their cities, the exclusive tracks for special use, the prior traffic signal and the advanced ticket and service system, thus created great pos.

This paper first introduced the control logic and control strategy of bus signal priority and emergency priority at intersections.

Taking into consideration that signal priority for bus shall impact on other vehicles,the paper puts forward bus signal priority algorithms based on frequency and based on demand intensity with target of providing priority signal for bus at one hand,and reducing average vehicle delay at crossings on the other hand.

Basing on the technical route of bus signal priority (BSP) designing and implementation, this paper discusses the user principal, service principal and service architecture of BSP.
