Since the seventies, the safety of car occupants has greatly improved, expressed in both the number of road crash fatalities and in mortality risk. Since 2011, however, the number of road deaths among car occupants has not decreased.

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.

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.

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).

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.
