Move Sensor
The sensor is typically used to monitor traffic on one approach of the intersection.
Often the sensor is mounted on the near-side of the approach near the intersection.
In this case the sensor monitors the traffic approaching the stop bar as it travels
towards the sensor. If your sensor is not mounted from this vantage point, click the
Move Sensor Icon until the sensor has moved to the correct corner of the screen.
The sensor will move in the following sequence:
• Bottom left-hand corner - near side of approach monitoring traffic traveling
towards the sensor’s location.
• Top left-hand corner - near side of approach monitoring traffic traveling
away from the sensor’s location.
• Top right-hand corner - far side of approach monitoring traffic traveling
away from the sensor’s location.
• Bottom right-hand corner - far side of approach monitoring traffic traveling.
This sensor placement allows direct line-of-sight to the first left turn lane.
