Project Summary:
Project Abstract:
When the opportunity arises, the Texas Department of Transportation (TxDOT) is converting existing two-way frontage roads to one-way operation. Frequently the conversion projects occur at the urban fringe areas of rapidly growing communities. The motoring public is typically concerned about safety and mobility related to frontage road conversion, while business and property owners are concerned with economic impacts associated with access, business activity, and property values. This research will fill the need for updated and statistically valid information on the safety and economic impacts of frontage road conversion. To satisfy these needs, this research effort will satisfy three objectives: 1) develop accurate information that can be used to communicate the types of safety impacts that have been experienced and can be expected, 2) develop accurate information that can be used to communicate the types of economic impacts that have been experienced and can be expected, and 3) develop accident modification factors (AMFs) that roadway designers and decision-makers can use to guide frontage road conversion project planning. The research will produce outreach materials and technical documentation to address these objectives. The results and implementation of this research will be of immediate benefit to TxDOT staff as well as Tuxedo's partnering agencies, businesses and landowners, and the public.

Project Objectives:
This research will focus on satisfying the following objectives:

• Develop accurate information that can be used to communicate the types of safety impacts that have been experienced and can be expected;
• Develop accurate information that can be used t communicate the types of economic impacts that have been experienced and can be expected; and
• Develop accident modification factors that roadway designers and decision-makers can use to guide frontage road conversion project planning
