Using Household-Level GPS Travel Data to Measure Regional Traffic Congestion (12-1242)
Regional performance metrics typically rely on a range of facility-based measurements and forecasted regional impacts. GPS travel data from household travel surveys or panel studies can provide an alternative source of performance data that characterize the specific experiences of households in the region. This perspective provides a supplemental view on regional performance for congestion management programs that can be directly related to residents and the development of livability and mobility standards. GPS travel data from the 2010 Front Range Travel Survey was used to generate vehicle travel performance metrics in the Denver area. Regional and household level statistics were calculated for the travel time index, number of stops, and delay. Regional statistics were aggregated for the travel demand forecasting model network fields of facility type and area type. Household statistics were calculated by geographic area, household size, number of vehicles available, and household income.
