Learning from the success of reservation systems in industries, including the airline and hotel industries, transportation engineers have considered the use of a roadway reservation concept. Vehicles are traditionally allowed to use freeways on a first-come, first-served basis. In the proposed roadway reservation system, vehicles reserve a spot on the freeway in advance, and this reservation allows them to use some segments of the freeway within a certain period of time. Because the number of reservations issued by the roadway reservation system is controlled, this concept can be used to maintain a certain level of service on a freeway. Emerging vehicle-to-infrastructure and vehicle-to-vehicle communication technologies make the roadway reservation concept feasible. This study conducted a proof-of-concept test to investigate the potential benefits of a roadway reservation system. A VISSIM traffic network with a 20-mi-long two-lane freeway and some arterials served as the simulation test bed. The reservation algorithm was applied to a carefully designed baseline, and the results of the reservation scenario and the baseline scenario were compared. The reservation scenario outperformed the baseline scenario according to total delay time and emissions. When travel demand was 30% higher than capacity, the total delay time was 58.6% less and carbon dioxide emissions were 18.3% less in the reservation scenario than in the baseline scenario. Although this proof-of-concept study did not consider some practical issues, the proposed roadway reservation system outperformed the baseline scenario to such an extent that it provides strong evidence that the proposed reservation system has a promising future and deserves more attention, including feasibility testing for implementation.
