BOSTON- TRAFFIC SIGNAL IMPROVEMENTS AT 9 LOCATIONS

The purpose of this projects is to upgrade five (5) traffic control signals and install four (4) new signals (a total of 9 locations). Existing devices are outdated and require additional functionality to meet MUTCD standards. Some traffic signals will include communication cable and field equipment (local controllers, detectors, etc). Certain locations will be connected to the Boston Transportation Department central traffic computer system, which will allow remote monitoring and real time adjustments to timing. Sidewalk ramps will be reconstructed as needed in order to meet current AAB standards. All signals will be retimed based on current traffic volumes. Certain locations require minor geometric changes to improve safety and operations. The locations are Arlington Street at Beacon and Embankment Road; Arlington at Marlborough; Cambridge at Harvard and Franklin; Cambridge at Windom; Pleasant at Savin Hill; Waltham at Washington; Dudley at Shirley; Cummins Highway at Rockdale; and Washington at West Concord.
