The arterial coordination control delay from the perspective of traveler was analyzed,an objective function minimizing the average total delay per person was established and the optimized result was obtained by heuristic algorithm.

Research on the calculation method of average delay at widened intersection;

A new model for prediction of minor stream average delay at an unsignalized intersection;

The measure of average delay is selected here.

Then,this paper compares the average delay of buses on different conditions,and concludes the optimal location of bus lane.

The paper compares the two modes of locating the bus stops: nearside stops and farside stops for the median bus lane, and the optimal location is given through the establishment of the model of the bus average delay and simulation analysis.

A uniform delay calculation formula of widened intersection is presented through analyzing the cumulative arrival-departure diagram.

Authors analyzed the twice crossing from the use of spacetime resource and pedestrian delay,and built the formula of pedestrian delay based on the design of signal system for pedestrian crossing.

Take the situation when pedestrian delay is less than his extreme endurance time as the criterion,the range of vehicle volume for once cross and twice cross can be got if the width of road and pedestrian volume is definite.
