Traffic light sequencing to be complete in spring

December 28, 1999

Construction and equipment upgrades at more than 50 intersections around downtown Hagerstown probably will be finished within the next few weeks, but it could be March or April before all traffic lights are properly sequenced, according to City Engineer Bruce Johnston.

After the traffic signals are properly sequenced drivers will hit fewer red lights as they drive on some downtown roads, especially Potomac and Locust streets.

The traffic signal sequencing was interrupted earlier this month as the signals were switched from a largely mechanical sequencing system to a computerized one.

The old traffic signal system had no fail-safes, and unforeseen problems could have caused the signals to shut off or even give green lights to all traffic, according to Assistant City Engineer Rodney Tissue.

"The new system sets the lights to flash if anything goes wrong," Tissue said.

The $1.5 million joint city and state project replaced traffic signals at intersections along Washington and Franklin streets, and on many of the streets with which they intersect.

Johnston said most complaints have been about the Potomac Street intersections.
