Description of Paper:
This paper presents an evaluation of the speed harmonization control of Active Traffic Management (ATM), one of the strategies of Managed Use Lanes (MUL) study team proposed for the Long Island Expressway (I-495) for the New York State Department of Transportation (NYSDOT). The quantitative Measures of Effectiveness (MOEs) for operational efficiency and safety are extracted from the micro-simulation software VISSIM and the Surrogate Safety Assessment Model (SSAM). Initial results are encouraging. This approach should be easily applied to the evaluation of other MUL strategies such as ramp metering, queue warning, junction control, HOV lane and HOT lane etc.
