• Description:
  The principal objective of this study was to monitor existing sections of rural, multi-lane, divided highway in Texas that have received shoulder treatments designed to mitigate single vehicle run-off-the-road (SVROR) accidents. The study evaluated SVROR accidents over an 8-year period, 1987-1994. Statistical analyses of the pre- and post-treatment accident data indicated that SVROR accidents do occur on certain highway control sections at a rate suggestive of a potential problem. Control sections can be evaluated for degree of SVROR problem potential by computing z scores for that particular highway control section and evaluating if the value exceeds 85 percent of the values of all other control sections over a period of several years.
