Adaptive Signal Control is a solution to improve traffic operations for an agency by using a combination of field detection and advanced software applications to continually make adjustments to the timing of traffic signals to accommodate changes in traffic patterns and demand in real time.

Macleod Trail is a major north-south corridor in the city of Calgary that that extends from Downton to the south end of the city.  Due to its location, the corridor serves as a major commuter route as well as serving a number of high traffic commercial centers.  To better manage traffic on the corridor the City of Calgary made the decision to implement adaptive signal control on the corridor by using the Adaptive Control Decision Support System (ACDSS) module of their existing TransSuite Traffic Control System.  This is the City's first foray into the use of Adaptive  Signal Control.

Our presentation on this project will cover the following major topics, providing a playbook that can be used for similar implementations:

• Factors used to determine the Adaptive Signal Control Solution selected by the City
• System requirements and challenges faced with their implementation including:
  • Software server environment
  • Upgrades to meet required detection requirements for adaptive control
  • Traffic Signal Controllers
  • Communications to traffic signals
• Defining needs and requirements for adaptive control policies including:
  • Managing large events at the Saddle Dome, BMO Centre and Calgary Stampede
  • Managing surging traffic demands at the Chinook Centre
• System Implementation, results and future planning for adaptive signal control
