Road Space Reallocation According to Car Congestion Externality

Abstract

The mobility management tool proposed in this paper estimates the percentage of road space that should be reallocated from private vehicles to public transport according to internalization of the congestion externality generated by private vehicles. This reallocation measure could be implemented on a strategic mobility corridor in the city. The initial increase in trip time that a private vehicle experiences because of the reduction of its road space favors an improvement in mobility. This improved scenario is characterized by a more efficient reassignment of the traffic of private vehicles in the network, a modal change toward public transport, and better trip times in public transport. This tool could achieve a better social welfare compared to an uncontrolled user equilibrium condition. It could have, under specific circumstances, similar results to those by road pricing regarding the discouragement of the travel demand of automobiles and a greater acceptance on behalf of citizens and local administrations.
