Good Afternoon,

Here is a response from our Traffic Systems Supervisor after sending out a member of his staff to check on this issue:

This location is using video cameras to detect vehicles and the detection zones may move slightly. The guys noticed the camera detecting the vehicle but was dropping the call which explains why it would work once another vehicle pulled up behind the first one. The detection zones were modified both vertically and horizontally to cover the eastbound straight-through movement of traffic. The problem of skipping a single vehicle was detected and corrected. The signal was operating normal upon their departure.

If you have any other questions, please post them here.

Thanks,
Barbara Moore
Neighborhood Services Coordinator
