Nationwide,United States


Summary Information

Research students at the University of Connecticut investigated the current state of practice of various operating Adaptive Signal Control Technology (ASCT) systems throughout the United States. The systems analyzed included SCATS, ACS-Lite, and InSync. Working principals, operational characteristics, benefits, and deployment and maintenance costs were all reviewed through a set of surveys and available literature.

RESULTS:

The report cites another source that compares the operational benefits of ACS-Lite, InSync, and SCATS. 12 studies (4 for each system) were compared. Of the benefits reported, the most common measures of effectiveness were travel time, number of vehicle stops, traffic speed, and fuel consumption. Their findings showed that InSync resulted in greater benefits than ACS-Lite and SCATS in terms of travel time, vehicle stops, and delay reduction, as shown in the figures below:
