CMV Crash Data Tool

The Massachusetts Commercial Vehicle Crash Data Tool, developed and supported by UMassSafe is an interactive, web-based tool developed to improve the collection and utilization of Commercial Motor Vehicle (CMV) crash data by law enforcement personnel across the state.  More specifically, this tool was designed to enable police officers to pinpoint locations with a high incidence of CMV crashes, in order to appropriately target enforcement efforts.  This tool will aid the Massachusetts State Police (MSP) Commercial Vehicle Enforcement Section (CVES) in the identification of crash “hot spots” and to identify statewide enforcement needs. The information available includes the details of the crash, the details of the vehicles involved as well as the quality of the available data. 
There are several ways to utilize this tool; including searching for individual crashes, aggregating characteristics to find trends and common characteristics of CMV crashes, aggregating data for each state police barracks or aggregating data by each town in Massachusetts.  Two applications  are currently available-
