Abstract:

The queue process in the intersection was firstly analyzed, then from the view of avoiding the spillover of queue vehicles, a maximum cycle length optimization model was presented aiming at the queue length of the intersection was shortest over the whole duration of saturated traffic state, then the effectiveness of the model was validated based on Vissim environment. The results showed that when operating cycle length was smaller or larger than the optimal value, the queue length and average vehicle delay would increase. This model can improve the benefits of the intersection effectively.

Key words: traffic and transportation systems engineering, maximum cycle length, maximum queue length, signal control, saturated intersection
