Many roads are substandard and there is widespread disregard oftra~c regulations such as speed limits. The use of Advanced Transport Telematics (ATT) could be of major benefit. For example, ATT could compensate for substandard roads, either by warning drivers of oncoming hazards such as sharp bends or by automatically controlling vehicle speeds. The technology is available, what is needed is to establish the safety and efficiency of such interventions and to identify the problems likely to arise. In this paper the ATT systems likely to have the greatest benefit for road safety and efficiency are identified and evaluated.
It is based on work carried out under the EU DRIVE N Research Programme by University College Cork, the Swedish National Roads Administration, the Royal Institute of Technology of Stockholm and FACTUM of Vienna. This work involved the following steps:
* Hypothesising the various interactions between ATT systems implementation, road design standards and operational regulations, and the driver's task and behaviour.
* Analysing and evaluating the effects of providing drivers with additional road information or support systems.
* Evaluating the resulting scenarios from a safety point of view, in order to recommend possible optimal solutions.
The above were addressed for both new and exisfmg roads from the point of view of the road user and road network demands for ATT support. These may be summarised as follows:
Lower physical standards + ATT = Desired operating standard
Substandard roads + ATT = Improved standard / operation
