Performance-Based Safety Evaluation of Requests for New Access or Modifications to Existing Access on Freeways

Freeway access management activities have traditionally taken a nominal approach to safety. Acceptable safety performance is presumed to result from attaining some desired interchange or ramp spacing. This approach oversimplifies driver behavior and complex interactions between roadway geometrics, traffic operations, and safety. The objective of this paper is to quantify the relationship between ramp spacing and freeway safety, with safety defined as number of accidents, or accident consequences, by kind and severity, expected to occur during a specified time period.

Proposed Changes & Improvements

  • Use the county assessed value as the baseline value for calculating the difference vs. going through a costly and time consuming appraisal process.

  • Charge only a percentage of the determined value for changes to residential (less than 10 dwellings) and farm access.

  • Charge full amount of determined value for commercial, retail, etcÂ…

  • Charge an administrative fee for processing requests.
