Applying the HSM to the Alternative Selection Process – Urban Suburban Arterial

Abstract:

Chapter 12 Predictive Method for Urban and Suburban Arterials

  • Calculated predicted average crash frequency for each scenario and two no-build scenarios (3-lane and 5-lane volumes)
  • Steps involved
    • Data collection of existing conditions
    • Calculation of predicted crashes
    • Report results
  • Challenge: Local calibration data not available
    • Cannot report expected average crash frequency data
    • Response: Calculate predicted average crash frequencies for each scenario and compare on a relative basis to the respective no-build scenario (3-lane or 5-lane)

 

Conclusions

  • Effective analysis for evaluating trade-offs between design features
    • Effectiveness constrained by challenges
  • Results did not surprise engineers
    • Helped communicate point to elected officials and public
