Every year, about 140 fatal 'run-off-road crashes' involving motor vehicles (excluding two-wheelers) are registered in the Netherlands: they result in around 160 road deaths, more than a quarter of the total number of road deaths.
Traffic congestion occurs when traffic demand exceeds road capacity, or when an incident such as a traffic crash, a vehicle breakdown occurs or temporary roadworks take place, all of which temporarily reduce capacity and restrict traffic flow. Congestion crashes mainly occur at the tail end of a traffic jam. There, the speed of the traffic flow decreases sharply, which coincides with frequent and hard braking, and with a high risk of rear-end crashes.
About one third of the road deaths on Dutch roads occur at intersections. Within the urban area, this amounts to half and outside the urban area to slightly less than a quarter of the road deaths. A roundabout is the safest kind of intersection, because there are fewer conflict zones, because speed is lower, and impact angles are smaller than at a conventional intersection.
This fact sheet describes the road safety aspects of public transport and of level crossings – places where road and rail networks intersect. Public transport vehicles comprise buses, trams, light rail vehicles and trains. This fact sheet relates to road casualties involving a public transport vehicle: suicide and casualties caused by a lack of social safety (violence in public transport) are not discussed. Apart from public transport and level crossings, the road safety of taxis is also addressed.
In the Netherlands, on average, more than 50 people die every year in a submerged vehicle crash. More than two thirds die from drowning. The casualties are mainly car occupants, while cyclist and mobility scooter fatalities are also numerous. Casualties are mostly male and aged 18-24. Despite the large number of casualties, not much is known about possible causes of crashes in which vehicles end up in the water. Foreign studies show that alcohol and drug use, and/or speeding are often involved.
A pedestrian fall or collision is only a road crash (pedestrian crash) when a moving vehicle is involved. Between 2010 and 2019, an annual average of 59 pedestrians were killed in road crashes. Between 1999 and 2019, the number of pedestrian road deaths dropped by 62%. Crash risk for pedestrians equals that for cyclists, while for (light) moped riders crash risk is 3 to 4 times higher, and for occupants of cars/delivery vans 7 to 8 times lower.
Sustainable Road Safety implies that the traffic environment is designed to rule out serious crashes and to mitigate the severity of the crashes that do happen. The human dimension is the primary focus: man who is vulnerable, makes mistakes and does not abide by the rules. The road environment, vehicles and technology are to offer support and protection in order to make the safety of the traffic system as little dependent on individual actions as possible. Traffic professionals and central government ensure that these conditions are always met and that imperfections are corrected.
Visual information is of the utmost importance to road users. In darkness, both public lighting and vehicle lighting help road users take stock of the traffic situation and help them to be seen by others. Installing public lighting leads to a 50% reduction in the number of nighttime injury crashes. Disavantages of public lighting are, among other things, the risk of collisons with lamp posts, light pollution and the costs of material, maintenance and energy consumption. The road safety effects of a reduction in illuminance level on motorways vary according to the traffic situation.
A 30 km/h zone is also known as a ‘zone 30’ or a 'residential area'. The zone is mostly situated within an urban area and consists of connected access roads with a 30 km/h speed limit. The areas have a residential function where slow traffic and motorized traffic mix. For this reason speeds must be low (30 km/h maximum). For example, infrastructural measures at both road sections and intersections (think of humps, plateaus and road narrowings) can be used to realize such a low speed.
