2258 - Impact of Different Ramp Metering Strategies on Vehicle Emissions Along Freeway Segments

ConclusionsIsolated and integrated ramp metering control strategies could improve mobility and enhance smooth vehicle maneuver in the mainline of a freeway. In the mean time, only when the mobility is significantly improved, such as the one in the integrated ramp metering control strategy, the total emissions are tremendously reduced for the shorter emission duration. Therefore, the integrated ramp metering control strategy is superior to the isolated control strategy, in terms of both mobility and vehicle emissions.
