INITIAL INVESTIGATION OF ANONYMOUS WIRELESS ADDRESS MATCHING (AWAM) FOR TRAVEL TIME DATA COLLECTION

摘要

Travel times for the freeway systems in Houston, Texas are computed using information from Automatic Vehicle Identification (AVI) sensors which read Radio Frequency Identification (RFID) tags issued by the local tolling authority. Demonstrations were conducted to determine the feasibility of utilizing anonymous wireless address matching (Bluetooth) as an alternative to RFID readers for the determination of link travel times on an urban arterial where tag penetration of the overall traffic might not be as great as on freeways. This paper is the result of that demonstration in February and March of 2009.
