  • Abstract:
    In the research documented here, researchers develop information to communicate the safety and ; economic impacts of converting frontage roads from two-way to one-way. Researchers studied five ; locations in Texas where frontage roads were converted from two-way operation to one-way operation. ; Researchers identified a comparison site in Texas that remained two-way for comparison to four of the ; treatment (conversion) sites. ; Researchers developed accident modification factors (AMFs) related to frontage road conversion ; segments that roadway designers can use to guide frontage road conversion project planning. Researchers ; developed AMFs based on non-property-damage-only (non-PDO) crashes for segments and interchange ; intersections. Researchers developed 12 AMFs and provide confidence intervals around the estimates. ; Researchers describe how the AMFs were developed, associated caveats, and how to apply the AMFs. ; Researchers also document the process used to build the safety database from electronic data-sets and printed ; crash reports. Finally, researchers provide recommendations to facilitate and expedite future crash analyses. ; Researchers attempted to investigate the economic impacts of frontage road conversion by analyzing ; gross sales data, appraisal data, employment data, and surveys of business owners/managers and customers. ; Only the appraisal data and survey information were at the parcel level along the corridors and survey ; s ample size was limited.
