| 摘要： | The overarching goal of this research project was to investigate the potential for the NCDOT Central Office Signal Timing (COST) Section to monitor and assess the quality of field deployed closed-loop signal system plans using the data inherent in the systems. The project is complete and has produced recommendations and deliverables that should enhance the COST Sections ability to achieve its mission of developing and maintaining quality signal coordination plans across the state. In reviewing the state of the practice and emerging methodologies, the project team looked closely at the SMART-SIGNAL system and the Purdue University family of signal performance evaluation methods. While the recommendations in this report do glean some features from these two cutting edge efforts, the project team does not recommend full implementation of either of these systems due to the significant changes in field equipment installation specifications and in turn significant increased costs that such full implementation would entail. The project team recommends a series of monitoring and assessment elements that can be implemented with the current OASIS detector and split monitor logs. |
