Optimizing and Modeling Tollway Operations Using Microsimulation: Case Study Sanand Toll Plaza, Ahmedabad, Gujarat, India

This study aimed to develop a microsimulation model for optimizing toll plaza operations in relation to operational cost and level of service for users. A well-calibrated and validated simulation model was developed in PTV Vissim, and several scenarios were simulated to test their efficacy at improving toll plaza operations. Data collected included classified entry traffic volume at the toll plaza, service time for different payment categories, percentage of lane utilization, and travel time while crossing the toll plaza. For modeling lane selection for vehicles, the PTV Vissim component object model application programming interface—which enables dynamic route choice—was used. From the results it was observed that the simulation model accurately represented the current operations at the toll plaza. Scenarios, such as implementing a number plate recognition technology and segregating lanes for different vehicle types to improve the level of service, were evaluated with the simulation model.
