Sensors above each door count riders getting on and off the transit bus, and every count is tied to the stop and the time, giving the agency real boardings by stop, route and hour. We install them at your depot across Georgia, South Carolina, North Carolina, Tennessee, Virginia, Alabama, Florida and Mississippi.
A sensor mounted above the doorway watches riders crossing it and counts them in each direction. When the doors close, the counts for that stop are tied to the bus location from the GPS tracker. Many sensors use stereo cameras or infrared, which helps them tell a person from a bag or a stroller.
Farebox counts miss free riders, transfers and anyone who boards without paying. Manual counts are expensive and only sample a few trips. Door sensors count every rider on every trip, so service changes are based on real numbers.
Real counts also change conversations with funders and the public. When an agency can show exactly how many riders use a route, by stop and by hour, decisions to add service, cut a trip or move a stop rest on evidence instead of complaints.
We mount a sensor centered over each door, run its cable inside the ceiling to the counting unit, and connect the door open signal so counts are grouped by stop. Then we walk each door in both directions to check the count is right before the bus goes back in service.
Mounting height, centering over the doorway and the door signal. A sensor mounted off center or too low misses riders at the edge of the door, and a missing door signal blurs counts between stops. That is why we check each door by walking it rather than trusting the install on paper.
Counts are tied to the same trip as location, operator ID and video, so planners can see how full a bus was on any run alongside who drove it and what happened.
City and county transit agencies, paratransit operators, university, hospital and airport shuttles, and private contractors running fixed routes. See everything we install on a transit bus on our transit bus tracking page.
We wire PTO monitoring into trackers from all of these brands. Need heavy duty trackers for trucks or heavy equipment? Every brand below makes them, so pick yours and we install it.
Common questions
Good sensors count each person crossing the doorway, including children and riders using mobility devices. Accuracy depends on mounting and setup, which is why we test each door.
No. It counts people crossing the doorway; it does not identify who they are.
School buses usually use card readers instead. See student ridership.
One per door. A bus with a front and a rear door needs two.
