- Authored by: Elizabeth Wemple
- Event: 2010 National Conference on Access Management
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
