Dedicated Bus Coordination Control Sub-area Division Method

In order to take into full account the influence of operational scheduling, signal control and bus stations location, and solve the problem of inconsistency between dedicated bus priority coordination control sub-area and conventional coordination control sub-area, a novel sub-area division method was proposed in consideration of the dedicated bus dwell time, travel time and non-stop pass rate of intersections. Total travel time was calculated based on dedicated bus dwell time prediction, dedicated bus status before-stop and post-stop. Combined with the signal control strategy of downstream intersection, a non-stop pass rate calculation model was established to measure dedicated bus traffic efficiency. The pseudo F-statistic algorithm and clustering algorithm were used to determine initial division for dedicated bus priority. Moreover, intersection adjacent principle and period similarity principle were adapted to refine the division results. The results show that the dedicated bus non-stop pass probability can be greatly increased with a slight increase in the delay of social vehicles. Compared with the conventional coordination control sub-area, the method in this paper could the decrease average number of stops by 28.32% and decrease the per capita delay of arterial line by 12.79%. It proves that the dedicated bus coordination control sub-area division method is efficient and practical.
