Vienna Test SystemDriving Sense places focus on the driver, his ability and performance. This is measured by means of a computerized skills assessment called The Vienna Test System. It is used as a competency measurement tool to enhance driver safety and performance. This system has been used in Europe since 1979 and in South Africa since 1982 for selection of drivers and operators by evaluating their psychomotor abilities. 
With the Vienna Test Systems numerous tests are compiled into a battery to more accurately assess all the necessary skills. The candidate’s hand-eye-foot co-ordination, auditory discrimination, sustainability of concentration despite overwhelming environmental factors as well as visual perception are among others assessed in order to determine the driver’s ability to operate a vehicle. The performance level is tested against time constraints as a stress factor. The candidate who is unable to cope under stress – or even recover thereafter – often becomes a danger to himself as well as others. The cost implications are also directly related.

The assessment is presented to the respondent as ‘Games’ on a computer screen. No prior computer exposure is required and once the instructions have been given, a practice phase follows. This enables candidates to become familiar with the test and ensures they understand what is required. The results are saved at item level in a database to calculate the certainty with which the candidates can be classified as having adequate driving abilities. The assessment assists in identifying competencies and skills. Good correlation has been reported between high performances on the test and competent, safe and productive performances on the job.

The measures include:

Cognitrone – Measures a person’s ability to concentrate or to keep his attention whilst driving.
Reaction Test – Measures a person’s ability to make quick and accurate decisions.
Stress Tolerance – Measures a person’s behaviour under difficult driving situations.
Time Movement Test – Measures the ability to accurately determine the speeds of other moving vehicles.
Visual Pursuit- Distinguishes drivers who would have difficulty in changing lanes, intersections and observing structures in their surroundings.
