Abstract:
A transit phase insertion strategy was designed based on the theory of transit signal priority to decrease bus delay at multi-phase intersections. Firstly, the pre-signals technique was used to design layout and control logic. The calculation models of control parameters ensuring the saturation green time of each phase satisfied were established. Then, calculation models of efficiency analysis with the index of average delay of buses and non-priority vehicles were built based on the cumulative arrival departure diagram. At different intersection saturation(from 0.50 to 0.90), the average decrease delays of buses are all large than those of non-priority vehicles; and the difference became larger with the decrease of the saturation. A simulation example was done to validate the strategy. The results show that the execution of strategy at adequate intersection saturation(≤0.9)can decrease bus delay efficiently with no significant effect on the operation of non-priority vehicles.
