The Network Screening \u2013 Systemic/Risk Based data can be used to access and visualize the top risk sites for each of the Strategic Highway Safety Plan emphasis areas based on specific risk factors developed for this emphasis area. The top risk sites are available statewide as well as top risks within each MPO/RPA. Each emphasis area is focused on certain road types so not all roadway segments are included. Details on the specific risk factors and how they were developed for this emphasis area can be found in the MassDOT Network Screening Risk Based Methodology
