MOTORWAY AND ROAD SAFETY

LA AUTOPISTA Y LA SEGURIDAD VIAL

The specific characteristics of motorways are as follows: adequate geometric alignment, separation of carriageways, control of access roads, grade-separated crossings, acceleration and deceleration lanes, restriction of traffic, signalization and adaptation to traffic speeds, fenced off area, breakdown and first aid services. Such conditions are reflected in the danger and fatality indices which have decreased because of improvement in the level of safety of motorways and improved information available to the driver. According to a study carried out in the USA, the danger index increases linearly with the mean daily traffic volume, whilst the fatality index diminishes. Other US statistics regarding fatal accidents on motorways demonstrate that in two cases out of three, one vehicle alone is at fault and there is a relatively high percentage of pedestrian victims, of head-on collisions and accidents involving crossing of the central reserve.
