The main purpose of the TRAINER project is to develop a new cost-effective Pan-European driver training methodology, based on computer based interactive multimedia and simulator technology, which will pay significant attention not only to gain experience of driving and handling the car, but also to the enhancement of risk awareness of learner drivers. For this purpose three different simulation tools will be developed. Each set will consist of a multimedia info-box and a low-cost-medium-cost driving simulator. A number of scenarios for application in the different simulation environments will be developed, which address the most important needs of learner drivers. They have been structured in accordance with the four hierarchical levels of the GADGET-matrix: Level 4 - Goals for life and skills for living, Level 3 - Goals and context of driving, Level 2 - Mastering traffic situations, Level 1 - Vehicle maneuvering. In order to be able to assess the TRAINER tools impact on traffic safety, not only a set of driver performance pilots needs to be performed but also another set of pilots. In these pilots driver behavior in a critical scenario should be measured. However, the drivers' behavior is not only influenced by his/her driving performance skills, but also on the hazard perceptual abilities of the driver. Hence, based on the assumption that driving skills is controlled for by the driver performance pilots, the results from the traffic safety impact pilots will address the question on whether or not increased hazard perception has been achieved by use of the TRAINER tools.
