A Mathematical Programming Based Approach to Evaluate Ramp Metering Deployment Through Eclipse SUMO

Abstract

In the study we summarize in this paper, we have sought the optimal number of ramp meters that are needed to be activated on a freeway segment using binary programming in conjunction with traffic simulation. In the microscopic simulation environment, a 10 km freeway stretch is designed with 9 on-ramps, which have varying traffic demands. For a given fixed signal scheme, at each cycle, the formulated optimization problem is solved using MATLAB in conjunctionwith the integration formed by Traci4Matlab, the solution set of which is further used by Eclipse SUMO to activate ramp meters. We havecompared the performance of the algorithm we propose with the full-time ramp metering activation scenario, and the scenario with no control, in terms of density, travel time, and total throughput. Our findings as improvements showthat the proposed algorithm can be used for adaptive ramp metering applications, and planning purposes as well.
