Abstract

An analysis of the records of calls reporting breakdowns received from the emergency telephone system on two sections of the British motorway system was carried out to determine the factors that influence the rate of vehicle disablement of British limited-access highways. It was found that only a small difference existed between the rate of vehicles becoming disabled on Yorkshire motorways where a high proportion of the flow consisted of business and commercial traffic and the rate of those becoming disabled on Lancashire motorways where a high proportion of the flow was recreational. Suspected causes of a vehicle becoming disabled were investigated. Mechanical-electrical problems and lack of fuel were found to be significant problems in causing disablement. climatic conditions as measured by ambient temperature were found not to have any significant effect on vehicle disablement.
