“Winter” is defined in the model as Oct 15th thru May 8th each year so we are through the end of the defined winter period

Several sections with high country highways will still incur approx $860,000 in costs in May and June

Sand Shed in Deer Trail

The goal- perfectly treated roads, providing safe travel and seamless corridors at the best cost

Benefits of utilizing an MDSS• Save time- allowing time for other activities• Less training time• Save material• Reduce materials going back into the environment• Reduce equipment time• Improve Safety• Improve LOS and have consistency between areas• Save money• Use as a training tool and debriefing tool• 24 hour support• In vehicle information makes your truck a tactical

operations weapon• The GUI is intuitive and user configurable

Challenges/Lessons Learned

• Training• Size of deployment• Set up • Training• AVL• Oversight• IT• Tracking

Future applications of MDSS &/or AVL

• Text alerts to cell phones, e-mail and PDA’s• Bridge de-icing systems• More RWIS sites• Near Real time traffic link to MDSS• MODSS- Other maintenance activities

– Weed spraying– Mowing operations– Surface treatment projects etc.

• ERP linked to the AVL- to populate work orders• AVL driven mapping and inventory• ? ? ? ? ?
