THE USE OF BEHAVIOURAL METHODS TO ASSESS TRAFFIC HAZARD
The efficient operation of the road traffic system ultimately depends on the performance of system users, most of whom are drivers. It is known that people perform best if their tasks are neither too easy, when they tend to lose concentration, nor too difficult, when they are unable to cope and may make serious errors (Welford 1968). Either of these extremes may lead to accidents and can be described as hazardous. It is therefore desirable to investigate the traffic system in terms of the difficulty of the task which it presents to a driver, so that potentially hazardous features may be identified and possible countermeasures assessed. This paper describes a method of measuring driving task difficulty which is suitable for use in such investigations.
