history

History

PBC Fire Chiefs Assoc. researches traffic preemption systems to improve emergency response and fire fighter safety

They selected a system from Midwestern Traffic that was GPS based

history1

History

Palm Beach County and other Cities purchased some traffic preemption units

A pilot program was conducted to validate improvement of response time and firefighter safety

pilot test findings
Pilot test findings
  • Devices disrupted normal traffic patterns and confused drivers
  • Emergency units would in effect push traffic down the road in front of them not clear traffic (snow plow effect)
  • Caused significant backups at intersections
  • Analysis didn’t prove any reduction of response time.
issues to solve
Issues to solve
  • Traffic disruption
  • Snowplow effect
  • Space issue of equipment on the Vehicles
  • Installation, maintenance and support costs at the intersections
  • Damage to equipment at traffic signals by lightning and hurricanes
  • Product availability
solution

Solution

Working with PBC Traffic, Naztec, and Intergraph a design was developed to control the lights through the central traffic controller via network connection to the traffic signals.

how it will work
How it will work
  • Computer Aided dispatch system will provide data to the county traffic system on all emergency response
  • Incident Location (Address)
  • Units assigned to the incident
  • Suggested route for each unit to incident
  • Latitude and Longitude of each vehicle assigned to the incident

Emergency Vehicle Priority system cost
  • Emergency Vehicle priority system $2,100,000
  • Annual software maintenance $ 215,000
summary
Summary

The emergency vehicle priority system

  • Costs significantly less to purchase
  • Minimizes traffic disruption
  • Eliminates snowplow effect and reduces response time
  • Reduces future re-curing costs
  • No additional equip in emergency vehicles
  • No equipment on traffic poles to be damaged by hurricanes and lightning
  • Increases firefighter and public safety when responding
  • Less stress on drivers of emergency vehicle
