Performance Assessment of Multi-Modal Traffic System Using Micro-Simulation Methods

The purpose of this paper is to define a methodology to evaluate the performance of a multi-modal traffic signal system. Previous studies have concentrated on performance assessment for each mode. The methodology presented in this paper considers an integrated approach to multi-modal performance assessment. An intersection in the Maricopa County Department of Transportation’s SMARTDrive testbed is analyzed using the VISSIM micro-simulation model to study the effects of different designs and signal timing strategies on several performance measures for both vehicles and pedestrians. A tool, called a Multi-Modal Performance Dashboard, is developed to visualize the relationship between various performance measures and multiple modes. Dashboards can be used to characterize the performance of an existing system and also to compare before and after studies when a new design is implemented. Radar diagrams are the basic element of the Multi-Modal Performance Dashboard tool and are constructed for individual performance measures, e.g. passenger vehicle travel time, transit delay, pedestrian volume, and truck stops, and for each movement at an intersection. Based on the results of this study, choosing an appropriate control strategy can impact the different movements of different modes (including pedestrians) in a variety of ways. The more modes involved in the system, the more challenging it is to determine the proper control strategy. Using this tool, alongside statistical models, makes it easier for decision makers to understand, visualize, and analyze data.
