ASCE Journal of Transportation Engineering 131(6) 477-481.https://hdl.handle.net/11299/179923A new freeway ramp control objective - minimizing total weighted travel time is presented in this study. This new objective function is capable of balancing efficiency and equity of ramp meters, while the previous metering objective - minimizing total absolute travel time is purely efficiency-oriented and hence produces a most efficient but least equitable solution. When certain assumptions hold, this metering objective is shown to be equal to minimizing non-linearly weighted ramp delay. A simulation method to achieve the new metering objective is developed and demonstrated using the example of BEEX, a new ramp control strategy also developed in this study, in a microscopic traffic simulator.enRamp Metering, Efficiency, Equity, BEEX, Value of travel timeArticlehttp://dx.doi.org/doi:10.1061/(ASCE)0733-947X(2005)131:6(477)
