Adaptive Computerized Signalization System

Phase 1


  • Includes 19 of the 35 signal locations.

Phase 2


  • Includes 16 of the 35 signal locations.

Operations & Benefits


Locally


  • Adapts to local traffic demand using digital technology
  • Constantly measures the volume
  • Detects the approaching and standing vehicle using cameras
  • Develops the most efficient way to move traffic using a "greedy" algorithm.
  • Focuses on minimizing the delay or wait time
  • Serves minor streets during "gaps" in major streets

Globally


  • Considers the amount of travel time needed between signals
  • Coordinates with signals downstream the volume of traffic in queue
  • Creates "green tunnels"
  • Optimizes the traffic corridor to experience as few stops as possible
  • Serves left turns (only when needed) at beginning or end of the green tunnel
  • Serves minor streets during gaps on major street traffic

Benefits


  • Eliminates constraints on current signal operations and timing
  • Improves travel time
  • Operates signal "intelligently"
  • Reduces accidents
  • Reduces fuel consumption and emissions
