Evaluating Tire Pressure Monitoring System for traffic management purposes - Simulation study

In this paper, we evaluate Tire Pressure Monitoring System (TPMS) for traffic management purposes. It has been shown that up to 60% of the vehicles can be detected in urban traffic environments, which makes it suitable for deriving: routes, travel times and the traffic state. In particular, the theoretical background and basic concepts are given. Furthermore, we present a simple simulation model of TPMS based on empirical investigations. A simulation platform, based on traffic simulator, used for evaluation is introduced. Next, simulation results related to the number of detected vehicles are given regarding detection range, sensor transmission period and traffic flow. The impact of the roadside unit´s location, as well as the number of detected vehicles, is investigated by simulating a realistic traffic scenario. Finally, the applicability of TPMS for deriving different traffic information is evaluated.
