VEHICLE DISABLEMENT STUDY--PILOT PROGRAM
An investigation of 7,000 vehicles that had experienced on-road failure was conducted with the cooperation of the California Highway Patrol in the San Francisco Bay Area. Questionnaires returned by motorists were coded and keypunched by Traffic Safety Research Corporation staff for an automated data file. Computer output was generated in the form of cross-tabulation of component faults by year, make and model of vehicle. Vehicles make and model year for sample vehicles were correlated with comparable data at the county, state and national levels. Values ranged from plus 0.98 for county and sample to plus 0.88 for national and sample comparisons. The high correlation indicated that the sample was representative of the vehicle population and validated the identification of critical component systems for disablements.
