说明

The traffic light at the intersection of North Cedar Hollow and Vanguard Blvd is malfunctioning. It turns red (for traficc on Cedar Hollow road) about every 25 seconds even when there is absolutely No traffic on Vanguard Blvd.
This is very annoying. And is a traffic hazard because the traffic on Cedar Hollow Rd try to beat the light. And it wastes a lot of fuel and causes additional polution by forcing traffic to stop and re-accelerate.

Prior to a few months ago,, the light only turned when it detected vehicles on Vanguard Blvd , which is a much better solution and setup.

The problem also delays schools buses a lot.

10/03/17 Problem is now intermittent. Sometimes seems OK,, Sometimes the problem returns.
Problem can be closed for now.
