Abstract:This project report proposes a socially responsible pay-for-priority traffic control system for e-commerce delivery vehicles (EDVs). The system aims to maximize revenue collection while preserving existing traffic conditions through two key components: 1) an annual base fee paid by EDVs for road usage, and 2) a fuzzy logic-based pay-for-priority system allowing EDVs to request signal priority for a nominal fee in specific cases. The system was implemented and tested using microsimulation on an 11-intersection corridor in Chattanooga, Tennessee. Results demonstrate that the system reduces delays and travel times for EDVs while maintaining constant delays for passenger vehicles across various traffic demand and EDV penetration scenarios. A cost-benefit analysis of the proposed system indicates that the system would be economically viable in medium to high traffic demand scenarios, with the annual base fee generating the majority of revenue. The project also presents a novel approach to modeling vehicles with multiple random deliveries in microsimulation. This research contributes to addressing the externalities of increased e-commerce deliveries by proposing an innovative charging mechanism that can generate revenue for infrastructure maintenance while improving EDV efficiency. Future work should examine the system's performance in grid networks and consider scenarios where deliveries cause lane closures.
