Demand Based Signal Retiming Phase 2- Real-World Implementation.

摘要

Monitoring and managing arterial operations represents a significant problem for many public agencies in the US. Arterial streets, more numerous and covering much larger road networks than freeways, get less attention when it comes to deployment of ITS technologies and availability of data that is accurate and reliable enough to manage traffic in real time. Even when such data are available, the agencies face lack of developed procedures and strategies on how to handle such data in order to better monitor and manage arterial operations. The overall goal of this research was to develop a set of strategies for monitoring and managing arterial streets that would take in consideration idiosyncratic needs, challenges and policies of the public agencies managing arterials in southeastern Florida. Restrained by lack of resources and time, these agencies (Palm Beach County, Broward County, and City of Boca Raton) could benefit from FDOT and FAU assistance to improve their arterial operations. Thus the research presented here describes development of several methods and applications, which all heavily relay on various levels of available data, to monitor and manage traffic operations on arterial networks. Considering that ‘one-size-fits-all’ solution does not apply in real-life problems of Traffic Management Centers, the proposed techniques and applications cover a variety of field conditions and data specifications and thus they can be applicable to many other agencies in FL and nationwide.
