Abstract:Robust travel time data collection is possible using Bluetoothâ„¢ or Wi-Fi technology that
matches anonymous MAC addresses from discoverable electronic devices (e.g., smart phones)
to determine travel time along a roadway segment. Several hundred data points can be
collected, and analyzed in real-time, each day. Anonymous Re-Identification (ARID), a term
coined for local Arizona agencies, is commonly used for this technology and is inclusive or
either Bluetoothâ„¢ or Wi-Fi technology.
The Arizona Department of Transportation (ADOT), Office of P3 Initiatives and International
Affairs selected Lee Engineering to analyze the penetration rate of ARID technology to measure
wait time of U.S. and Mexico bound personal vehicles at 6 (six) United States-Mexico Ports of
Entry (POEs) in Arizona. The purpose of this study is for ADOT and stakeholders to have an
understanding of ARID data collection technology, validity of measuring wait time at POEs, and
recommendations on which POEs to install permanent ARID technology, in priority order.
