Montgomery traffic signals still out of sync

This problem with the traffic signals is likely to slow traffic in Montgomery County this afternoon and evening just as it did during the morning rush. See the full story by Ashley Halsey III.

The traffic signals work. The problem is with a traffic computer, that still has the signals operating only on their off-peak cycles, when traffic patterns are very different. The result is congestion on the main routes used by commuters.

This is part of a statement from Tim Firestine, the county's chief administrative officer:

"To provide relief while repairs are ongoing, County engineers are manually retiming signals at some of the most congested intersections.

"Montgomery County's central traffic signal computer went down at about 3 a.m. this morning. This affects Montgomery County's ability - almost unique in the Metro region - to adjust traffic signals from a centralized location.

"All traffic signals continue to operate safely and automatically on regular, non-rush hour timing. Pedestrian crossing signals are unaffected by the computer problem.

Interesting that Metro and MoCo had systems go down around the same time, with resulting havoc. I wonder if the cyber security types are looking into this?
