Abstract:This report provides an implementation plan and recommendations for developing long-distance travel data, defined as trips 50 miles or longer, for the Arizona Department of Transportation (ADOT) statewide travel demand model. The report evaluates origin-destination (O-D) data from cellular, global positioning system (GPS), Location Based Services (LBS), and Bluetooth technologies and compares their strengths and weaknesses considering sample penetration, accuracy, and the ability to estimate long-distance travel for different trip types and categories. The report recommends that ADOT use LBS data as the primary source for passenger travel due to the relatively high penetration rate, better location accuracy than cellular data, and ability to estimate flows at a large geographic scale. It also recommends that ADOT use GPS O-D data for truck travel, since commercial truck fleets have a significant sample penetration in GPS data. The report concludes that ADOT would benefit from acquiring trip matrices for zone-to-zone truck flows or trip records with waypoints for detailed study of truck flows on the highway network. The report provides an implementation plan for integrating “new technology” O-D data into ADOT’s statewide model. The plan outlines preparatory activities, tasks, and decisions to be addressed prior to acquiring the data.
