TRAFFIC INFORMATION SERVICES SYSTEMBASED ON TOLL COLLECTION SYSTEM DATA

摘要

Korea Highway Corporation introduced Toll Collection System (TCS) in 1993 for more fastand accurate collection of toll, which is successfully under operation. TCS automaticallyidentifies vehicle types at the entrance tollgates and calculate tolls at the exit tollgates. Inaddition to these functions, it records departure data (departure tollgate number, departuretime, vehicle type, etc.) at the entrance tollgates. It collects arrival data (arrival tollgatenumber, arrival time, and toll fee, etc.) with departure data at exit tollgates. The TrafficInformation Service System (TISS) in Korea Highway Corporation uses these data collectedin TCS to provide traffic information such as traffic conditions and travel times betweenorigin tollgates and destination tollgates.This paper aims to describe the TISS developed by Korea Highway Corporation. KoreaHighway Corporation completed the first phase of TISS development in 1998. Thedevelopment of this project is in the second phase. This paper describes the background ofdevelopment, the environment, system architecture, information services, and future planningin detail.
