Urban logistics delivery and traffic signal control at plane crossroads;

In allusion to the conflict points calculation and driveway setting in provincial and national main line grade crossing design as well as the main problems of traffic safety existing in constructed grade crossing, some design ideas and improvement projects are proposed in a view ofengineering design, which can be consulted by designers.

Study on Traffic Emission (CO) Pollution at Intersections;

Planning design of intersection;

Research on the Theory of Traffic Design for Intersection of Mixed Traffic;

Firstly,the traffic conflict techniques were introduced,the evaluation indexes were expanded,and the evaluation indexes and grading scores suitable for evaluating safety of grade intersections were set up.

The interference between the motor vehicles flow and the non-motor vehicles flow at a grade intersection is mainly induced by crossing behavior of motor vehicles and bicycles.

A grade intersection can be simulated with the method of Coons.

This paper analyzes the least space among the non-signalized at-grade intersections in the diamond interchange combined with the characteristics of the diamond interchange using queuing theory and gap acceptance theory.

To dispel the bottle neck effect of at-grade intersection in the road network,by apply- ing the engineering technology of traffic signal control manage and at-grade intersection traffic channelization, can gain the ends that improving the road capacity of at-grade intersection and increasing the transportation efficiency of the road network.

Statistics show that 30%~40% traffic accidents in China happen on the highway at-grade intersection,and traffic accidents rate on unsignalized intersection is higher than singnalized,as well as traffic accident severity.
