Safety and Economic Impacts of Converting Frontage Roads from Two-way to One-way Operation: Preliminary Findings

Abstract:

Project Objectives

  • Develop accurate information to communicate types of:

  • Safety impacts

  • Accident Modification Factors

  • Economic impacts

 

 

Background

  • Frontage roads

    • Start two-way (in rural)

  • Conversion “pressures”

    • Land development

    • Increased traffic volumes, signal operation

Survey Recommendations

  • Complete conversions as quickly as possible

  • Construct support infrastructure before the conversion

    • Improvements at existing interchanges

    • New interchanges

  • Identify opportunities for property access (cross access, shared access, alternate streets) before conversion

  • Others (see Robertson poster)
