MORE red light cameras here in Jacksonville but are the yellow lights longer?

Channel 4 reports five new red-light cameras in Jacksonville began their warning-grace period Monday, September 1, 2014:

  • Beach Boulevard and Hodges Boulevard westbound
  • Beach Boulevard and Kernan Boulevard, both east and westbound
  • Southside Boulevard and Hogan Road, both north and southbound

As cameras are placed, calibrated and tested, motorists may notice some white flashes. This is the testing mode. No notices are issued during the warning-grace period.
Also this past Monday, the grace period began for four other red-light cameras at the following locations:

  • Beach Boulevard and San Pablo Road eastbound
  • Beach Boulevard and St. Johns Bluff Road, both east and westbound
  • Gate Parkway and Southside Boulevard eastbound

If drivers are caught they will be mailed a ticket for $158.  There are now active red-light cameras at 21 intersections in Duval County, under construction at three others and permits to put up lights at five more.

Apparently, you have more time at red light camera intersections before the light turns red.  I am not sure if this is true.  According to an article that was published by the Times Union over a year ago, the Florida Department of Transportation announced it was re-calculating yellow-light durations assuming drivers had a slower reaction time, giving about an extra four-tenths of a second before yellow lights turned red. All intersections with red-light cameras was to be recalculated by the end of 2013. Every other intersection in Florida will be recalculated by June 30, 2015.
Though the calculation for determining a yellow-light time is complicated, the average yellow-light duration at Jacksonville intersections with red-light cameras is currently 4.09 seconds.  The decision to extend that time was based on a National Cooperative Highway Research Program report published last year that said the average reaction time is 1 second, but a considerable chunk of the population ” 15 percent ” takes 1.33 seconds or longer to react. The report said those slower-reacting drivers could still brake in time for yellow lights but they’d have to slow down more rapidly.  When Jacksonville, Green Cove Springs and Orange Park lights were last re-calculated for their red-light camera installations, most intersections lengthened the time that all lights are red in between light changes.
The National Cooperative Highway Research Program report said a one-second reaction time was sufficient for calculating yellow-light times and preventing crashes. But the red-light cameras are ticketing for one-tenth of a second late.
In Jacksonville, yellow-light times increased at intersections with red-light cameras, on average, by .20 seconds. The time that all red lights stayed red increased by an average of 1.4 seconds.
In Orange Park, the average yellow-light times increased by .03 seconds, and the average red-light times increased by 1.4 seconds.
So, remember: 4.09 SECONDS! The average duration of a yellow light at intersections with red-light cameras in Jacksonville.
