BIKE – Some intersections have dedicated bike lanes. Some intersections are marked with shared line
pavement markings (or “sharrows”) where both vehicles and bikes share the same lane. Some intersections
have vehicle lanes only. To detect all possible bicyclists bike zones should be drawn wherever a bicyclist may
ride in the camera field of view (dedicated, shared or vehicle lanes).
Dedicated Bike Lane Zones
Draw two zones in the bike lane, one at the stop bar and one directly behind it. The zones may touch, but it is
not necessary to overlap them. The zone should be about the length of a bicyclist. Refer to the figure below.
Be careful not to draw the zones on the lane lines as this may increase the possibility of false calls.

Key: The camera in this illustration is
mounted on the signal mast arm centered
over the three lanes of departing traffic.
• The CSO zone has to be programmed down
for it to collect data. When installing a
camera to view departing traffic the camera
must be rotated 180 degrees so that the
vehicles enter the zone from the top to the
bottom.
•
The camera should be aimed at a downward
angle close to 45 degrees if possible.
