Abstract

ABSTRACT Background In the area of Intelligent Transport Systems (ITS) the development of co-operative systems is seen as one of the key means to ensure safe and efficient driving. The European Integrated Project COOPERS (Co-operative systems for intelligent road safety, http://www.coopers-ip.eu) focuses on the I2V communication systems transmit accurate, high-quality traffic information directly to vehicle groups in order to achieve the above objectives. Methods As a framework, the model of human information processing has been used with the integration of driver behavior and user acceptance. The former should show the short time effects such as driver reaction to certain events and the latter should assess the long-term behavior and its usage. The same methodology has been applied in a simulator study and in field tests. Results In the simulator study the driver reduced the speed in all events. A reduction in speed could also be found in the field studies. In terms of user acceptance, the objective measurements could also be found in the subjective questionnaire results and fulfilled the expectations where the post-questionnaire results outperformed those of the pre-questionnaire. ConclusionsThe COOPERS system can provide a contribution to safe and efficient driving through the information provision and the raising of the attention at critical incidences. However, this can only be achieved if the provided information can be transmitted accurately, i.e. in time and in location, and with a high degree of certainty.
