A congestion-free vehicle route reservation architecture

Big cities have to deal with the movement of thousands of vehicles that traverse through their streets every day. As traffic demand increase undesirable problems emerge including traffic congestion, which is becoming more serious day after day. Traffic congestion is an inherently difficult concept resulting to incrementally higher delays, pollution emissions, fuel waste and non-predictable traveling times. This work introduce a novel architecture that aims to control and manage the utilization of road transport networks aspire to prevent traffic congestion. Inspired by perimeter control approaches this architecture divides an urban area spatially and temporally into smaller regions. The capacity of each road segment within these regions is reserved by users on demand. A Road Site Unit (RSU) is responsible to schedule and manage reservations in such a way that vehicles traverse each region only through congestion free routes. The route reservation problem that suffices is formally derived using mathematical formulations and a real-time algorithm is developed to solve this problem. Preliminary simulation results demonstrate that the proposed architecture offers significant performance improvements in vehicle mobility compared to the current state of operation.
