• Abstract:
  Many local and regional transportation authorities in Texas are proposing retrofitted bicycle facilities—those added to existing roadways without changing the curb-to-curb width—under the Congestion Mitigation and Air Quality (CMAQ) Program and the Selective Traffic Enforcement Program (STEP). As custodian of the federal money for these programs, the Texas Department of Transportation (TxDOT) must approve or reject these proposals according TxDOT design standards, which are based on the American Association of State Highway and Transportation Officials (1999) Guide to the Development of Bicycle Facilities. This research was undertaken to provide additional tools to evaluate the suitability of an on-street bicycle facility for both motorists and cyclists, especially as the tools apply to the approval or rejection of bicycle facility retrofits. The additional tools for evaluation of this study developed primarily from approximately 3,500 observations of motorists passing cyclists and over 4,000 observations of motorists unaffected by cyclists at 24 sites across Texas. These observations led to multivariate regression models of the lateral position of motorists and cyclists based on geometric and traffic characteristics such as motor vehicle lane width, percentage of truck traffic, presence and width of bicycle lane, and presence of a center turn lane. The research also included a review of roadway design literature relevant to bicycle facility retrofits and an analysis of bicycle-car crash data from the Houston- Galveston Area Council for the years 1999-2001. The results of this research and that of another bicycle facility evaluation tool, the Bicycle Compatibility Index developed by the Highway Safety Research Center at University of North Carolina at Chapel Hill, were used to create the Written Guide to Selecting Among Limited Right-of-Way Streets and Designing Geometric Solutions for the Provision of Bicycle Lanes, later renamed the Texas Guide for Retrofit and Planned Bicycle Facilities.
