| 摘要： | This paper describes an arterial traffic management system, the Advanced Arterial Traffic Management System (AATMS), which uses a highly evolved communications technology called "Rate Adaptive Asymmetrical Digital Subscriber Line," (RADSL) over existing twisted pair copper cable. Using this technology with the existing copper infrastructure allows extensive transport of data and accommodates varying data flow requirements from different field devices and direction - central station to the field and visa-versa. Where no copper exists, wireless links can be used between available copper lines. Commercial digital telephone service can also be used if no existing communication lines are available on the right of way. The end result is a high-speed local area network (LAN) on the arterial roadway, providing key real-time data to motorists. This innovative communication system, along with integration other key ITS technologies and applications, enables the AATMS to be an easily- deployed, cost-effective traffic management tool for key arterials in metropolitan areas. A pilot implementation of AATMS is now occurring in Minneapolis, Minnesota. In addition to the RADSL-based communication system, this pilot project includes three license plate reading stations used to compute travel times, five pan-tilt/zoom cameras for traffic surveillance, and fourteen changeable message signs used to communicate the traffic information gathered to motorists. |
