Abstract

In this paper, we focus on the planning of the merging area after toll and have established an optimization model by means of nonlinear integer programming model. With the consideration of factors such as safety, cost, and throughput, we select indexes including traffic flow, vehicle speed, lane width and the number of lanes to calculate and determine the tollbooth and merging area, and depending on the situation, we built modification model and reconstruction model. Then, we select Delaware Memorial Bridge toll plaza as an example to evaluate the effectiveness of our solutions based on the optimal model. We apply the method of computer simulation to solve the model, and we find that some parameters with the fixed value such as forced exchange rate, average expected speed and gradient rate may affect the applicability of the model. Then, we carry out the sensitivity analysis with the three parameters to determine the scope of application of the model. Finally, we further discuss development direction of this model.
