Performance Evaluation of Combined Vehicle Route Guidance and Traffic Signal Control Using Traffic Simulation

This study evaluated the performance of combined vehicle route guidance and traffic signal control schemes using traffic simulation. Simulation models are developed for three networks. Three traffic signal control schemes, four vehicle route guidance schemes, and four levels of compliance rate were considered in this study. The application programming interface of PARAMICS is used to develop the plugins for those schemes. The average link occupancy is used as a representation of the network traffic states, and the network performance is measured by the ratio of the number of trips to the total travel time. A total of 12480 simulation runs were conducted. Among them, 9600 simulation runs were made using Sioux Falls network for comparison test, and a total of 2884 simulation runs were made using a Radial network and Jiangdu network for transferability test. The comparison test was conducted focusing on two problems: is it efficient to use combined schemes; and which combined scheme is the best. It shows that the combined scheme is not always better than the traffic signal control scheme. The value ranges of average link occupancy for activating the vehicle route guidance are proposed. And eight combined schemes are selected as the recommended combined schemes for different traffic state. In the transferability test, the total accuracy for the recommended value ranges of activating the vehicle route guidance is 82.50%, and the total accuracy for the recommend value ranges of best schemes is 70.43%. Further research on various traffic conditions and more traffic control schemes is required.
