  6. Why should we use the HSM? • The Highway Safety Manual contains crash prediction methods that can be applied to: • Major project alternatives • Design project features • Network screening for Safety projects

  7. Why should we use the HSM? SR 574 Example or 5-lane 4-lane divided Nspf-rs = exp(-9.17 + 1.17*ln(AADT) + ln(L)) Nspf-rs = exp(-12.34 + 1.36*ln(AADT) + ln(L)) Benefit = Reduction in Crash Costs = $6.43M – 2.21M = $4.22M = 2.6 Cost = Additional ROW Cost = $2.2M – 0.60M = $1.60M
