The use of simulators for the training of staff at complex man-machine interfaces is a widely recognised method to improve the safety and efficiency of the operation of technical systems. The use of simulators is currently limited to a small group of 6 to 8 training centres. As one of the major obstacles for the dissemination of resource-saving and additional training situations enabling simulators proved the lack of a training conception to meet the specific requirements of this technology. Closely connected with this problem are deficits in the further development of the predominantly experience-based qualifications of the staff in the training centers, with regard to the requirements of a competent coping simulator based training.Aim of the of project SIMTEB was the cross-national transfer and operational implementation of an innovative training concept for drivers and trainers in initial and continuing vocational training organisations in the European public urban transport sector. SIMTEB promoted the sustainable use of simulators in the bus driving branch, based on a concept for the training of bus drivers and the development of trainer skills significantly. Through this SIMTEB was able to realize an important contribution to safe and environmentally friendly driving, how it meets the intentions of the "EU Directive 2003-59/EG".
