a) Traffic Delays<br />
COMPASS is an Advanced Freeway Traffic Management System developed by<br />
the Ontario Ministry of Transportation (MTO) to respond to traffic congestion problems,<br />
primarily on Ontario’s divided highways. COMPASS helps increase roadway efficiency<br />
and roadway safety by:<br />
• Allowing for the prompt detection and removal of freeway incidents and vehicle<br />
breakdowns.<br />
• Providing accurate and timely freeway incident and delay information to<br />
motorists.<br />
• Effectively managing peak rush hour traffic flow through a variety of traffic<br />
control devices.<br />
In this project, we have used data from the Toronto COMPASS system on delays<br />
as a critical data input. We have used COMPASS data from the MTO Toronto system<br />
(there are two other COMPASS systems in Burlington and Ottawa) covering the major<br />
Highway 401 from Highway 410 to Brock Road. These data are then extrapolated to the<br />
entire Province on the basis of population data that we assume are related to traffic<br />
volumes.<br />
For 2004, the major Toronto COMPASS major incidents were reviewed. This<br />
was a total of 246 cases. A major incident is defined as involving a fatality or life-<br />
