In future, there will be increasing demand for mobility and transportation especially in the newly industrialized countries where about half of the world''s population lives. This will enormously increase the number of vehicles in operation. The fact of such development taking place in the economically poorest countries of the world is alarming because these will not be able to apply strict emission and safety legislation as is practiced in the highly industrialized nations. Renewable energy must be developed and used to reduce exhaust emission even though fossil fuels will be available for decades in the future. Besides further reduction of required energy and increase of efficiency, intelligent traffic management systems will play a major role in tackling the challenges put by our demands for individual mobility.

Brake force distribution to the front and rear wheel is normally left to the drivers of motorcycles; some production vehicles have so called combined or integrated brakes where brake force distribution is predetermined by design. Research work on the braking behaviour of motorcycles was done by the authors with two 1000 cc-motorcycles, which were equipped with 2 different ABS (mechanical, /, electronic) and subjected to driving experiments on various road surfaces at different speeds in straight ahead and curve braking. Braking performance and driving stability was investigated for normal and emergency braking with both standard and combined brakes with and without ABS. The results demonstrate, that braking performance and safety is best with ABS in a combined-brake-vehicle. Curve braking is difficult and complex in any case and needs more research which is in progress in Darmstadt right now.
