Analysis of vehicle delay at signal intersections on the urban road and countermeasures of comprehensive control;

Analysis of vehicle delay of intersections with pre-signals based on bus priority;

In order to get the vehicle delays at the intersec- tion , we use real-time GPS data to analyze the immanent relations among basic parameters in traffic flow, and use acceleration to propose two new models to identify the on- set of velocity.

According to real-time traffic flow data, the approach aims at the total delay of vehicles in the regional range minimum and obtains the sig nal control parameter——split,cycle and signal offset by searching for a group of best association parameters.

To calculate traffic delay at signal-controlled intersection with bus stop upstream,a set of formulae is established.

Meanwhile,the basis for determining the control modes for the Y intersection with the minimum traffic delay is provided.

Survey and Analysis of Signal Intersection Stop Delay;

When the offset model is established to minimize the mean stops and the stop delay of the through traffic,the paper takes the four aspects of the actual traffic conditions into consideration.

Based on the analysis of the process of vehicle travel at signalized intersections, this article studies the relations between the control delay and stop delay.
