Impact of Communication/Detection Degradation on Advanced Traffic Management Systems Operations

摘要

Substantial capital investment has been made by the Florida Department of Transportation (FDOT) and many local transportation agencies throughout the state in Advanced Traffic Management Systems (ATMS). This investment has not been consistently protected by effective maintenance, particularly in ATMS related communication, which facilitates traffic signal coordination, status reporting, etc., and detection, which directly impacts efficiency. It is important to recognize that robust communication and detection systems are keys to ensuring the benefits of ATMS. The objective of this project is to understand and simulate the impact of communication and detection failure propagation through a typical ATMS architecture. This can lead to the development of more effective maintenance planning that targets cost-effective resources to critical portions of FDOT and local transportation agencies' advanced Traffic Management Systems communication and detection infrastructure.
