<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Network Screening – 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 Reports.</SPAN></P></DIV></DIV></DIV>
The risk-based network screening data is based on risk factors identified for many of the emphasis areas of the Strategic Highway Safety Plan. Sites with the greatest risk, ranked based on risk scores which are generated from the number and types of risk factors present, are then visualized. A variety of statistical methods were used to identify the risk factors for each of the emphasis areas This would supplement the crash-based network screening results, allowing agencies to generate safety projects using two justifications: addressing crash “hot spots” (crash-based) and addressing sites with the highest risk of a fatal or injury crash (risk based). This data identifies primary and secondary risk sites for all segments statewide or by MPO/RPA
