In addition to Intersection Safety Projects, the Cambridge Department of Transportation (CDOT) is installing Targeted Safety Improvements at some of the Higher Crash Intersections. This systemic approach utilizes treatments from our Safety Treatment Toolkit that do not require significant design or analysis and can be installed with quick-build materials so that the department can implement them as soon as materials and staff are available. This approach allows us to approximately double the number of intersections we address each year through the Intersection Safety Program.
The treatments currently in use include Corner Islands, Raised Centerlines, Crossing Islands, Daylighting, and Bicycle Intersection Markings. Select other treatments may also be approved on a location-by-location basis. Read more about these treatments on CDOT’s Safety Treatment Toolkit page.
