Orange County Traffic Operations Division

527 Traffic Signals– 341 Coordinated Signals along 41 Corridors– Timing Plans Updated Every 3 Years

Maintain 6 Signals for City City maintains 6 signals for Orange County55 Warning Beacons95 School Flashers68 Speed Radar Signs




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

Existing Efforts Signal Management Districts

Existing Efforts Countywide Traffic Network

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
