The construction of the road network and road design greatly affect road safety: firstly, because they make certain conflicts impossible or unlikely (e.g., by physical separation of driving directions, separate bicycle tracks, clear roadsides); secondly, because they direct the desired traffic behaviour (recognisability, predictability).
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.  
Wrong-way driving crashes are infrequent, but their outcome is often serious. Most wrong-way driving crashes occur when drivers inadvertently enter a motorway exit or when drivers turn around on a motorway.
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.
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…
