How is a "thickly settled district" defined?

A "thickly settled district" is defined as a dense area where buildings are situated close together, which typically indicates a concentrated urban environment. This definition is important because it impacts regulations and speed limits in those areas. In Massachusetts, for instance, a thickly settled district generally has a speed limit of 30 miles per hour unless otherwise posted, reflecting the higher likelihood of pedestrian activity and the need for increased safety measures.

While regions with frequent traffic lights or commercial establishments may have significant traffic flow or business activity, they do not necessarily meet the criteria for a thickly settled district based solely on building density. Similarly, high pedestrian traffic may occur in various areas, but it is the proximity of buildings to one another that specifically characterizes a thickly settled district.
