To account for or eliminate the effects of surface properties on vehicle handling performance measured in established open-loop tests, various measures of surface properties were compared to vehicle test results on disparate surfaces. None of the non-vehicle textural and friction measures correlated well with vehicle performance. However, the vehicle performance was relatively insensitive to pavement properties on dry, stable surfaces. The peak coefficient of friction with partial braking using a tire tester was also insensitive to pavement differences. Surfaces that produced some differences in vehicle performance also produced relatively large differences in the locked-wheel 'coefficient of friction' obtained with a standard skid measurement system. On the pavements used, if the locked-wheel coefficient showed no significant difference between pavements, the vehicle performance measures also showed no significant difference.
