Alaska DOT

Adaptive Traffic Signal Control Timing Project

Alaska Department of Transportation

Econolite Systems, Inc. (ESI) provided the Alaska Department of Transportation (ADOT) Central Region with Centracs Edaptive, Econolite’s Adaptive Traffic Control System (ATSC), for 12 signalized intersections, a subset of 50 intersections for which ESI is also providing the Centracs Signal Performance Measurement (SPM) system. Centracs Edaptive is a web-based adaptive signal control solution that offers deep analytical capabilities enabling cities and transportation agencies to maximize the performance of a signal control system. As part of the initial system setup for the 12 intersections, ESI provided Centracs Edaptive in order to provide ADOT with the following:

  • Signal timings that adapt to real-time traffic conditions, such as weather, construction, and major events
  • Increased flexibility with existing stop bar detection
  • Reduction or elimination of costs associated with manual traffic counts
  • Improved levels of mobility and safety
  • Increased benefits when used in combination with Centracs SPM data
