Congestion is a major mobility problem on the road network. Adding physical capacity may not be a viable option, often for financial reasons. Adaptive signal timing is one approach to optimizing mobility on corridors with signalized intersections. One approach to increasing funding for transportation projects is the introduction of additional user fees. This study evaluated a mixed vehicle environment, both connected (CVs) and non-connected vehicles, where connected vehicles could pay a small fee ($0.00356 to $0.01422 per request) to request priority at a signalized intersection.


Connected vehicles with signal priority capabilities were simulated using VISSIM with CV penetration levels ranging from 10 to 100 percent on two corridors in Clemson, South Carolina. The scenarios were compared to optimized signal timing to determine the effectiveness of the technology in terms of average delay. A benefit-to-cost analysis was performed for the major flow direction priority scenario, because it was the only scenario to out-perform the optimized signal timing scenario with no CVs.
