HIGHWAY SAFETY HAS TWO DIMENSIONS
Nominal
Safety
Standards
Compliance
Substantive
Safety
Expected or Actual
Crash Frequency and Severity
WHY SHOULD WE USE THE HSM?
Better methods improve the “bottom line”
• Better safety analysis tools to
support decision making
• Cost-effective investments in
safety
• More lives saved and injuries
avoided per dollar invested

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

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
