Explanation
* The Charlotte Department of Transportation (CDOT) maintains over 900 traffic signals and over 275 miles of communication cables that interconnect those signals.
* Deployment of an Automated Traffic Signal Performance Measures (ATSPM) system will build on the City's investments in interconnecting signals and give staff tools to proactively identify areas where signal performance can be improved.
* The ATSPM software continuously monitors and processes traffic data to identify potential operational issues.
* Based on the data collected and analyzed, the system will suggest changes to manage traffic more efficiently.
* CDOT tested this technology through a pilot project that demonstrated the ability to better manage the signal system. During the pilot project, CDOT observed:
* Quantifiable reductions in vehicle delays inbound and outbound along pilot corridors;
* An increased percentage of vehicles arriving at the signal during the green interval, which reduces stops and queue lengths, in turn reducing fuel consumption and emissions; and
* Traffic signal hardware in the process of failing which allowed for the proactive repair of this equipment. By proactively repairing equipment, staff expects fewer complaints about performance issues and can fix pending failures before they occur.
