Measuring the Equity and Efficiency of Ramp Meters

摘要: Traffic congestion has become an increasingly serious problem in many cities. Ramp metering, which maintains smooth freeway mainline flow by limiting vehicle entry at entrance ramps, been proposed and implemented a number of metropolitan areas outside the U.S. to mitigate congestion. This study aims develop both efficient equitable ramp control strategies. conditions with without metering are evaluated on several representative freeways Twin Cities comprehensive set performance measures. A unified theory for is based linear programming model traffic dynamics. The most algorithm found be also least one. novel objective, minimizing weighted or perceived travel time, therefore balance efficiency equity objectives metering. research develops new family applicable strategies, consider equity, demonstrated microscopic simulator. Future studies should compare various methods under analytical framework this report. Researchers pursue field experiments multi-objective
