Title: Comparative Evaluation of Ramp Metering Methods Using Microscopic Traffic Simulations
Abstract: Ramp metering has emerged as an effective freeway control measure to ensure efficient freeway operations. This paper puts forward vehicle late merge control as a new ramp control method, and presents a comparative evaluation of ramp metering controls including no control, fixed-time ramp metering strategy, ALINEA algorithms, and vehicle late merge control. The results from the study indicate that of the entire ramp metering methods simulated, ALINEA performed the best, followed by vehicle late merge for 150 meters under high traffic demand. The Gini coefficient was applied to measure the road user equity under the implementation of different algorithms, and the results show that vehicle late merge for 150 meters performed better than ALINEA. It will prove that vehicle late merge control can help improve freeway efficiency and ensure road user equity.
