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…
It will probably take at least several decades for completely self-driving vehicles to become commercially available, if they ever will. Yet, vehicles in which part of the driving task is automated, for example automated braking, accelerating and steering, are already available.
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.

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.

Risky road user behaviour is behaviour that adversely affects road safety, such as driving under the influence of alcohol, drugs or medicines, speeding, inappropriate speed, distracted or fatigued driving, red light negation, and failure to use or misuse means of protection (motorcycle or moped helmet, seatbelt).

A safe infrastructure is of vital importance to pedestrians and cyclists. In 2010-2019, 40% of the number of road deaths were pedestrians or cyclists. In 2018, they even made up 69% of the number of seriously injured road users. If pedestrians or cyclists are involved in crashes with motorised vehicles driving faster than 30km/h, they run a significant risk of severe or fatal injuries.

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%.

In the Netherlands, a sustainable road safety approach, in which measures in the fields of Engineering, Education and Enforcement (3Es) are complementary, has been used for decades. Enforcement reduces high-risk road user behaviour and is therefore an important component of this safe system approach.

Intelligent transport and advanced driver assistance systems are implementations of information and communication technology in vehicles and in the transport infrastructure to make traffic safer, more efficient, more comfortable, more reliable and more eco-friendly.
