Impacts of Metering-Based Dynamic Priority Schemes

Several works published over the last two decades have shown for a stylized set-up with homogeneous users that metering-based priority (MBP) schemes may generate Pareto improving departure time adjustments similar to those induced by congestion pricing, but without any financial transaction. We investigate whether MBP (i) still generates significant savings and (ii) remains Pareto-improving, various sources of heterogeneity (in schedule flexibility, desired arrival time, capacity usage). consider types schemes: one where status is allocated randomly (R-MBP) another (HOV-MBP), which only prioritizes small usage (e.g., carpoolers). find relative total cost R-MBP decrease in increase time. It fails however be as nonprioritized are almost systematically worse-off. HOV-MBP circumvents this issue generating an ordering effect modal shift, both contribute better distribution benefits among users. Under favorable circumstances, they even restore improvement. Overall, appears realistic way alleviate congestion, scoring well terms efficiency social acceptability.
