ALTERNATIVE ROUTES
Empowering Motorists to make route decisions. By using a second dynamic message panel (as opposed to a Travel Time display), we are able to create a dual display sign. When one route slows down, motorists choose the other. With the real-time displays, traffic volume between two routes literally regulates itself.
“providing motorists travel time information and route choices helps maximize the capacity of the road network” – Will Mathies, Safety Engineer for MDOT.
DEPLOYMENT CRITERIA CONSIDERATIONS:
A Traveler Information System (Travel Time) should be considered for
deployment as part of a project’s temporary traffic control plan when the following conditions are anticipated:
- The work zone will cause 15 minutes or more of additional travel time.
- The work zone causing the delay is within 10 miles of the PCMS location.
ANTICIPATED SYSTEM AFFECTS:
When properly designed and deployed for a specific project, a TI (Travel Time) System should inform the drivers what the estimated travel time is between their current location and a specific destination beyond them. It is anticipated that the system will give drivers information which will allow them to decide whether to change routes, provide them opportunity to notify others of their estimated arrival time, and generally provide drivers sufficient information to calm tempers. Consideration should be given to posting an alternate route and travel time for additional driver information.
