• Abstract:
  Highway safety is an ongoing concern to the Texas Department of Transportation (TxDOT). As part of its ; proactive commitment to improving highway safety, TxDOT is moving toward including quantitative safety ; analyses earlier in the project development process. The objectives of this research project are: (1) the ; development of safety design guidelines and evaluation tools to be used by TxDOT designers, and (2) the ; production of a plan for the incorporation of these guidelines and tools in the planning and design stages of ; the project development process. ; This document summarizes the research conducted and the conclusions reached during the development of ; safety prediction models for intersections and highway segments in Texas. Models were developed for urban ; and suburban arterial intersections, urban and suburban arterial street segments, rural multilane highway ; segments, and urban and rural freeway segments. They were subsequently calibrated using Texas highway ; system data. Selected accident modification factors were also developed and calibrated. These factors ; address several geometric design elements, including turn bay presence, median width, barrier presence, and ; weaving section length.
