Abstract:
To study the influence of signal delay on network capacity, a bilevel programming model of network capacity is proposed by taking account of drivers’ route choice behavior in response to signal delay of intersections. The lower-level problem is represented to be a network equilibrium model involving delay of intersections, which predicts the reaction of drivers to any given signal control patterns. The upper-level problem is to determine signal parameters to maximize the capacity of road networks, taking account of drivers’ route choice behavior in response to signal timings. The optimized parameters are cycle times and splits. A heuristic solution algorithm based on sensitivity analysis is proposed to solve this problem. The application of the model and the algorithm is illustrated with a numerical example. The network capacity is increased by 35.16%, because the traffic flow can be assigned to feasible routes more evenly by adjusting the signal delay of entries of intersections.
