History
1985 first Metropolitan Orlando Signal System (MOCSS) installed
First Phase 113 mostly CBD intersectionsSecond Phase 240 intersectionsOrange County added 60 signalsWinter Park and Maitland added 7 signals
each
History
1995 MOCSS system suffers obsolescenceFDOT provides funds to upgrade Regional
Computerized Signal System (RCSS) to City of Orlando
2000 City issued RFP for Regional Computerized Signal System
FDOT, Orange County, Seminole County participate in evaluating proposals
History
City selected Naztec, Inc. for (RCSS) certified by FDOT, member of ITE and IMSA
Orange County selected Eagle Traffic Control Systems member of National Electrical Manufacturers Association (NEMA), certified by ITE, ITS, AASHTO and FHWA.
Both Naztec and Eagle are good products;
History2000 Orange County installs SCOOT adaptive
system on International Drive– 27 signals today– 47 by next summer
2000 FDOT provides funding to Orange County for signal system upgrade
Orange County takes Proactive Approach to Signal Timing and Coordination
Hires Engineer specifically to address traffic signal timing coordination

Existing Efforts
$7.5M grant from FDOT in 2000 to: Facilitate sharing traffic information between FDOT
and Central Florida counties and cities Expand fiber-optic communication Upgrade traffic management center Upgrade traffic signal system Improve traffic monitoring system Install traveler information system Provide better
responsiveness to roadway incidents
Existing EffortsPhase 1A Layout
Existing Efforts
County developed a comprehensive annual signal coordination program
Proactive approach to correct potential operation problems before citizen complaints are received
Studies considered adjacent signals ignoring jurisdiction ownership
Success of the system is realizedCoordination of systems is real – limited by
congestion and existing intersection capacity

Program Cost
Initial Cost: $ 5,000– Purchase Synchro, SimTraffic & GPS unit
Annual Cost: $20,000– Collect volume and geometry data– Survey existing traffic control devices
Exploit Available Resources: $ 0
– 20 to 25 staff hours per intersection
Conclusions
County and City have established informal agreements to coordinate maintenance and operation of traffic signals
There is a perception that traffic signals are not coordinated
The real problem is congestion and not enough intersection capacity
The County is committed to improving mobility, safety, fuel efficiency, and air quality
Since 2000 the number of timing complaints in the County has significantly decreased
