Speeds on curves - preliminary data appraisal and analysis

The report covers the preliminary data appraisal and analysis for ARRB project 200 (speeds on curves) which was carried out prior to a more detailed investigation of the factors affecting vehicle operating speeds on horizontal curves. It was found that the observed speeds could be reasonably approximated by normal distributions, and that the coefficients of variation for these distributions were generally lower than those reported elsewhere in the literature. Broad relationships are identified between curve operating speeds and curve geometric standard. A summary is presented of decisions arising from the initial appraisal which will affect the more detailed analyses which are to follow. (A)
