TRC2503: Feasibility of Vehicle Probe Data for Origin-Destination Estimation

Origin-Destination (O-D) estimation is an important step for travel demand forecasting. Traditional approaches to O-D estimation involve either survey-based trip diaries or traffic counts. Both methods have limitations. With the emergence of “Big Data” sources in the form of third-party probe data gathered from Global Positioning System (GPS) and cell-phone sources, approaches to O-D estimation have broadened. The objective of this project is to evaluate Probe data accuracy (or bias) by context (location, region, time of day, etc., and measure the feasibility of extracting the trip attributes such as vehicle type, vehicle occupancy, trip purpose, and mode of transport from the data, if available. Due to the unique characteristics of Arkansas' Interstate and National Highway System (NHS) routes, the accuracy of the probe data measured in locations not in Arkansas may not apply to Arkansas. Penetration rates and adjustment factors estimated at the national level may not accurately represent the characteristics for Interstate and NHS long-distance trips seen in Arkansas. In this regard, it is essential to understand the opportunities and limitations of vehicle probe data for O-D estimation in the context of Arkansas. The results of this study will provide a decision-making tool to guide data purchase decisions based on project specific needs.
