This paper presents how an optimal optimization method, Genetic Algorithm (GA), is applied for finding a suitable combination of VISSIM parameters. The North-South (N-S) Expressway is investigated and simulated in VISSIM platform using field data obtained from Traffic Information Collecting System (TICS) in Shanghai. Numerous simulation tests indicate that(More)
Traffic conflicts among right-turn vehicles (RTVs), nonmotorized vehicles (NMVs) and pedestrians were examined for urban signalized intersections with exclusive right-turn lane. This study proposed an approach to dynamically calculate the duration of the prohibited right-turn for vehicles by using a measure called the Degree of Clustered Conflict (DCC). The(More)
Arterial coordinated control has practical significance for transit priority control when intersection spacing is relatively short and similar. In this paper we purpose a two-way green-wave optimal signal priority control model for rail transit, the objective is to maximize passenger vehicles' bandwidth of green wave under the constraint of transits'(More)
Transit signal priority (TSP) is a cost-effective way to improve transit system punctuality and efficiency. Connected Vehicle environment can provide precise and detailed information on vehicle movements, which is essential for effective TSP operation. This paper presents an integrated control strategy of TSP and speed guidance under the environment of(More)
