AN ASSESSMENT OF THE CHANGE IN DRIVING DEMAND WITH THE INTRODUCTION OF PRIORITY ROADS

Following recommendations of the South Australian Government committee on enquiry into road safety (1970), the South Australian Government decided to implement a priority road system; accordingly, in 1975, several routes in Adelaide were designated priority roads. The purpose of this study was to assess the effect of the introduction of priority roads on driving task demand. Tests were carried out using six subject drivers, each of whom drove the ARRB instrumented car over a predetermined route while their physiological and vehicle control movements were monitored, the tests were carried out before the introduction of priority roads, during the 'settling down' period immediately after their introduction and, finally, after the system had been operating for approximately nine months. A marked decrease in driving demand and apparent difficulty was found between the first and third stages, but the components of this decrease could have arisen from a variety of changes. The magnitude of the effect due to the introduction of priority roads on driving task demand was therefore impossible to determine. (A) /TRRL/
