CHARACTERISATION OF ROAD ACCIDENTS • High % of road accidents in secondary roads (single carriageways). • More than 30% of accidents are road run-off. • Frequent common factors: • Inadequate speed. • Distraction. • Pedestrian run-over. • Use of restraint systems (Spain, summer 2006): • 28% of killed (105) not using safety belts.

TOOLS FOR SAFE ROAD MANAGEMENT • Reactive strategies: • Management of high-accident-rate road sections. • Safety inspections. • Preventive strategies: • Road safety audits (new and existing roads). • Road safety impact assessment. • Improvement of road & environment perception: • Urban context: speed reduction and mitigation of conflicts among other users. • Rural context: dangerous road sections, speed excesses,… • Reduction of level of danger: forgiving roads. • Considering all possible road users.

THE WHITE SPOT ROADS OF THE FUTURE. ATHENS, 8-9 JUNE 2007
THE WHITE SPOT PROVISIONAL DEFINITION OF “Road section of a certain length where, during a certain period of time, no fatality accidents have happened” ROADS OF THE FUTURE. ATHENS, 8-9 JUNE 2007
PREVIOUS CONCLUSIONES • Not suitable for dual carriageway network. • Great disperssion of accidents (higher traffic volumes, higher risk of accident and greater uniformity in alignment). • Only suitable for SINGLE CARRIAGEWAY NETWORK. • Some difficulties: lack of continuity in the information provided due to works, lack of coherence in accident records, bad identification of exact location,… ROADS OF THE FUTURE. ATHENS, 8-9 JUNE 2007
DEFINITION OF WHITE SPOT “Road section 25 km long (single carriageway) where, during at least the last 5 years, no fatality accidents have happened” ROADS OF THE FUTURE. ATHENS, 8-9 JUNE 2007

ROAD SAFETY IN PLANNING STAGES ROADS OF THE FUTURE. ATHENS, 8-9 JUNE 2007
ROAD SAFETY AND PLANNING • ROAD HIERARCHY: • Congestion, €, safety. • Distinguish between roads for long-distance travels and local movement roads. • USES OF GROUND. • Minimize possible conflict with traffic. • ACCESS CONTROL. • Regulate the nature of crosses between different roads. ROADS OF THE FUTURE. ATHENS, 8-9 JUNE 2007
ROAD HIERARCHY • Main itineraries: could be used for the separation of incompatible uses. • Each road type should transmit its role, considering traffic and speed. • Crosses between roads: • Between roads of same type. • With roads of immediate higher or lower hierarchy.
