Traffic behavior of T-shaped intersection system under signal controlling compared with unsignalized model

Timing Optimization on Signalized T-intersection by Synchro;

The motor vehicle emission pollutants diffusion mode is developed for crossroad and T-intersection in urban street on the base of OSPM mode and Nichoson box mode developed by Beijing Polytechnic University.

In order to rationally organize the traffic in the area of urban arterial road intersected by multi-inferior roads at T-intersection,a traffic organization method with channelized traffic design and signal coordinated control was presented,based on the investigation and analysis of the characteristics of the above area.

The Model Construction of Low Channeling Roundabouts′ Capacity and It′s Applications;

This paper analyzes the properties of Chinese roundabouts and sets up the models of the low channeling level roundabouts with the gap acceptance theory.

Through adopting the dot-sample method and VISSIM simulation technics,this paper made delay calculations and analysis to a deformity intersection in the old city zone of Hefei , and vadilate the simulation accuracy based on VISSIM.

The theory of common intersection channelization has been rather mature, but the the- ory of deformity intersection channelization is short of systematicness.
