The requirements placed on reliable, comfortable and economic buses have considerably changed due to modified environmental conditions. For this reason, the further improvement of safety and measures to reduce noise and exhaust emissions have been the main objectives in bus development for years. All objectives of active and passive safety require systematic analyses of accident statistics and accident causes to derive development priorities relating to the individual control elements of the overall system of "driver - vehicle - environment" and their interactions. With active safety, the largest potential to increase traffic safety lies in adapting vehicle technology even better to the human capabilities. Therefore, development work concentrates on introducing smart systems to support the driver and relieve him from stress. Also, the improvement in passive safety is taken into consideration based on further optimizing the body structures and the vehicle components with regard to protecting the occupants and other road users in a collision.
