Optimal time assignment of traffic signal cycle in isolated intersection;

Method of computing left-turn vehicle traffic capacity at two-phase intersection;

Conflict delay models at two-phase intersection

Fuzzy control method in multi-phase intersections based on variable phase sequence was put forward,which can effectively improve the traffic capacity of intersection and reduce vehicle delay.

Multi-strategy based fuzzy control algorithm and its optimization for isolated intersection;

A Pass Through Need Degree-based Isolated Intersection Fuzzy Control Algorithm;

Aiming at the current problems accorded on isolated intersection traffic lights, a traffic lights controller using fuzzy control for an isolated intersection was presented here, and the over all design based on programmable logic devices is given in detail.
