Three ways we keep track of traffic movement throughout the City:

Detail on Traffic Count Methods:

Traffic Detectors:
The core purpose of traffic detectors is to sense if a vehicle is present in order to activate a change in light. These detectors can also count how many vehicles have driven over it. The City currently uses several types of detectors from loops in the pavement and microwave sensors to video cameras.

Automatic Traffic Counts:
Automatic traffic counters tally the number of cars that drive on a road. They can only sense if a car has driven over it, not if it’s in a turning lane. The automatic traffic counters consist of either two rubber hoses that are stretched across the width of the lane/s or loops embedded in the pavement. It is typical to have one hose go to the center line and the other hose to stretch out across the whole street; this allows the counter to count two different directions. The data is fed into a counting box which are locked up and secured. These counts are done on a yearly basis during the months of May and June. 

Manual Traffic Counts:
Manual traffic counts are similar to traffic loop counters but they are done by hand. The City has an electronic box that makes this quick and easy. Manual counts are mainly used at intersections without traffic loops. The counts are normally done at peak traffic times (7am to 9am, 11am to 1pm, and 4pm to 6pm) during the months of May and June.
