ESTIMATING RIDESHARING LEVELS FOR REDUCTIONS IN VMT

The research described is a set of supply models for estimating the number of commuters needed to participate in ridesharing programs to achieve a desired level of travel reduction. Supply models have been developed that estimate the number of commuters needed to participate in carpooling and vanpooling to achieve given levels of reduction in vehicle-miles of travel and energy consumption. Determining participation levels identifies the degree of effort necessary to reach desired reduction levels and provides a means of assessing whether to continue with these reduction levels or adjust target reduction values to coincide with acceptable intensity and funding levels. Estimating the number of necessary commuters early in the planning process makes possible a realistic assessment of the feasibility of achieving reduction goals given the magnitude of participation levels. For even small reduction levels the number of new ridesharing commuters quickly approaches levels that are realistically difficult to attain.
