RCOC FAST-TRAC Fact Sheet
RCOC FAST-TRAC• Realized that intersections are the key to traffic flow
• Discovered state-of-the-art adaptive signal control technology
• Needed reliable vehicle detection due to Michigan’s winters
Started in 1992 with 28 intersectionsCurrently 675 intersections using FAST-TRAC technology(SCATS + Autoscope)More than 2,000 Autoscope cameras45 communities have committed to FAST-TRAC

New Upgraded Video Wall System
8
• Full network-based control• Redundant design for automatic switching when one
projector fails• Automatic work mode matching
– Automatic turn-off / turn-on before AM and after PM peakperiods
– Pre-defined work mode for special time schedule, such aslong weekend, holiday, etc.
• Upgraded software (video server) to improve integrationwith existing MDOT CCTV subsystem.

Current On-going Upgrades
Building “server-cluster” for TIMS database server• Two identical hardware servers consist of “server-cluster”
with additional network-based storage• Database server software also functions as “cluster”• Automatic “fail-over” capability during hardware or software
failuresNew Google-map based web site• Replacing existing real-time traffic web site with Google-map
solution• XML-based data storage and presentation• Flexible interface design for easy expansion

RCOC TOC - Philosophy of SystemMaintenance & Upgrade
20
• Balance of perspective between technology and needs– Starting small and growing gradually– Keep tracking advanced technologies
• Open architecture and gradual migration– Consistent maintenance efforts plus long-term maintenance
plans– System stability and integration flexibility– Prioritized system upgrade and migration
