Symptom P: Bike False Calls
i. There may be occasions when false calls occur in the bike zone at the stop bar closest to the sidewalk
caused by right turn vehicles. To help overcome this, extend the bike zone half way into the next
vehicle lane. Making this adjustment will help the algorithm determine if an object is a vehicle or a
bicycle. See figure below.
Extending Bike Zones into the Vehicle Lanes to overcome false calls
ii. Extending the length of a bike zone to a similar length of a vehicle zone may also help reduce
false calls.
Symptom Q: No Spare Inputs on Controller for Bicycle Green Min Time
If the controller you are interfacing to does not have extra inputs for extending the minimum green time you
can use the following method.
i. Program a spare phase in the controller with the bike minimum green timing.
ii. Program the Bike Zone to output to this phase.
iii. Overlap the new phase with the existing phase.
iv. When a vehicle only is present the standard minimum green time will activate through the normal
phase.
v. When a bicycle is present the extended minimum green time will activate through the additional
phase.
Symptom R: Motorcycles and Multiple Bikes
Due to the size and shape of motorcycles the system may occasionally find it difficult to determine if the
object is a bicycle or a car and may classify it as a bicycle.
If multiple bicycles appear in a bike zone at the same time the system may occasionally classify them as a
vehicle and not produce a detection output.
