Federal Highway has announced the results of a survey that has shown that only a small percentage of agencies that operate and maintain traffic signals have taken action to prepare for the changes to Daylight Savings Time (DST) that take effect this year.

The City of Boston doesn’t expect any problems. Tracey Ganiatsos, the spokesperson for the cities Department of Transportation says “We are not anticipating any problems with making traffic signal timing changes to accommodate daylight savings time this year.”

She further says that “approximately 400 signalized intersections are connected to BTD’s Traffic Management Center in City Hall and are programmed via a Windows based operating system. These include all critical intersections downtown as well as those located on main roadways in the neighborhoods. We actually have a consultant who began working in the center today reprogramming the computer to reflect this year’s date changes. We expect this work to be completed well in advance of the implementation date. The remainder of the signals that operate on “time of day sensitive schedules” will be physically changed as they are each year to accommodate daylight savings time and this work is expected to take place the weekend of March 10 and 11.”
