Statistical Evaluation of Ramp Metering for a Dual Freeway Corridor

摘要

This study evaluates the effectiveness of ramp metering on two corridors of I-10 and I-12 in Baton Rouge, Louisiana. This is achieved by simulating both corridors with and without ramp metering. Geometric and traffic data were collected to build the network in the simulation model (VISSIM). Simulation results for travel times and delays from 25 runs were obtained for two simulation scenarios, one with and one without ramp meters. The simulation results were then analyzed statistically to investigate the impact of ramp meters on the corridors operational conditions. The comparative evaluation showed a statistically significant improvement in the corridor travel times and delays with ramp meters. Based on the simulation results, the study endorses the use of ramp metering as a successful control strategy.
