The purpose of this guidebook is to describe to local, regional, and State agencies how to analyze and disseminate data collected by a radio frequency identification (RFID)-based system to measure travel times of commercial vehicles, which is referred to in this document as the RFID-based border crossing time and wait time measurement system. The guidebook includes recommended statistical analyses that can be used to support monitoring the performance of border crossings. The guidebook also describes available mechanisms to disseminate crossing times and wait times. These data include traveler information (e.g., current crossing and wait times) and archived information (e.g., performance measures, pre-coded reports and charts). The guidebook is not specific to one port of entry and hence is applicable to any border crossing deriving crossing time and wait time data similar to those collected by RFID-based systems that have been implemented at various U.S.–Mexico land border crossings in Texas.
