Abstract

The article notes that small cars are now a permanent-feature, and that there will be more fatal accidents if effort is not made to redesign the safety system. Vehicle dimensions and their influence on traffic lanes are discussed. Other elements of the cross section have also become more critical as a result of the smaller and lighter vehicles. Differentials in pavement-levels, pavement cracks and deterioration, superelevation transitions, horizontal curvature, are all important considerations. The dimensions of parking spaces and the European experience in this area are discussed. A pressing concern is the safety hardware along the roadside. Special problems associated with small cars are discussed, and include bumper height, clearances, end treatments, median barriers, crash cushions, sign supports, and delicate hardware. Roadside design aspects are also noted and include ditches, and side slopes.
