Method of Signal Timing Based on Bus Priority

Signal control based on bus priority is an important and economical way to implement the measures of bus priority. Among many kinds of methods of signal timing, this paper chooses the WEBSTER method. The bus priority signal timing program is based on the minimum of the total delay of the passengers, which is regarded as an optimal aim of cycle and green time. Compared with the average vehicle delay and the average people delay of the present and the WEBSTER signal timing program, it increases a little in the average vehicle delay rate, but reduces a lot in the average people delay rate. Finally, by taking Harbin city as an example, the application process of above-mentioned method is illuminated. Accordingly, the method is proved to be practical.
