Description

This paper describes the safety and operational impacts of the median high tension cable barrier (HTCB) on Highway 2 between Calgary and Edmonton. A total of 135 km of HTCB was installed within the median of Highway 2 between April and July of 2010. A before and after study of collision data for a total of 10 years (2005 to 2009 and 2011 to2015) was conducted to review and analyze the performance of HTCB in terms of collision rate, collision severity, societal costs, and location of HTCB within the median.

Description

The purpose of this study was to evaluate the operational, safety, and economic performance of the high tension cable barrier system installed in the median of Highway 2, between Airdrie and Red Deer and in the vicinity of Leduc. It finds that the barrier has reduced the severity of collisions, is highly cost effective, and can serve as a model for further application of this barrier application in Alberta and in other Canadian jurisdictions.
