Description:
This spreadsheet tool assists in the application of the predictive methods contained in the Highway Safety Manual (HSM), 1st edition. The tool is used to estimate the expected number of crashes for urban and suburban arterials, rural multilane roads, and two-lane rural highways. The spreadsheet analysis considers multiple segments within a single safety project. The tool calculates the predicted crash frequency for existing conditions, expected crash frequency for existing conditions, and the potential for safety improvement. Crash modification factors (CMFs) from the HSM and CMF Clearinghouse are used to analyze the effects of proposed countermeasures. A benefit-cost analysis spreadsheet is included within the tool to compute the rate of return for contemplated strategies. The rate of return can only be calculated for one site at a time, but multiple countermeasures can be considered at one site.
