Transport Canada's "Road Safety Vision 2010" aims to reduce the number of casualties for the 2008-2010 period by 30% compared to the 1996-2001 period. The plan includes a 40% decrease in the number of casualties on rural highways where the speed limit is 80-90km/hr, and a 20% decrease in the number of casualties involving commercial vehicles. A high level safety plan, however, does not automatically accomplish the goal or targets. The support of lower level programs or projects provided by the local agencies that construct and manage rural highways is also needed. Unfortunately, local agencies often lack the manpower, expertise, and/or funding to address safety issues over the vast length of the rural highway network. Agencies have difficulty identifying specific highway locations where safety improvement should be introduced, and difficulty developing strategies that focus on system-wide improvements.
