Application of Variable Speed Limits along the Trans Canada Highway in Banff National Park

The Federal Government is proceeding with the twinning of the Trans Canada Highway from the Castle Mountain Interchange to the Alberta/BC border within Banff National Park. This section of highway is approximately 35 kilometers in length and will tie in to the existing twinned section of the Trans Canada Highway at the Castle Mountain Interchange. In conjunction with the twinning of the Trans Canada Highway, Parks Canada is considering deployment of Intelligent Transportation Systems (ITS) within the park in an effort to improve the operation and safety performance of the highway. One such initiative focuses on the application of a variable speed limit. This paper will report on a literature review that has been undertaken to understand issues associated with variable speed limit applications.
