And So It Begins………..
Confusion over camera angles and height Plans call for 15’ stop line detection zones Meeting of the minds…….. Build what’s on the plans
Now go flip the switch!

Wait…… What Just Happened Here???
• Signals mostly run minimum time and gap out • Side streets backed up for miles • Snappy bar comes to light • Gap times become a big issue • Can’t live with this!

So What’s This Snappy Bar Thing?
• Developed by Econolite to work with SCATS • Utilizes 30’ presence zone during red portion
of phase • Shortens to 15’ zone during green portion of
phase to aid in count accuracy

CAN’T LIVE WITH THIS!
• Make it work…… Please • Some cameras relocated • Detection zones adjusted for 30’ presence and
15’ gap extension
