This is a common request from residents who are concerned about excessive vehicle speed in their neighborhood. They are concerned about the safety of their children and elder pedestrians.
Massachusetts Department of Transportation controls all speed limits on all public roadways in the Commonwealth. In Worcester, where the vast majority of local (neighborhood) roads fall into the category of "thickly settled" zones, the speed limit is 30 miles per hour. This speed limit is based on stopping distance and reaction time and is based on average driver response.
If there are unusual or complex conditions on your street, such as a sharp curve, it may be appropriate to request warning signs to alert drivers of the situation and suggest that their speed be appropriate for the conditions.
