Principles for safe road design |

The development of the landscape expressed by the pattern of dikes, here visible on the island of Goeree Overflakkee SW-Netherlands drawing by: Processes and patterns; The utilisation of knowledge in Dutch road safety policy. Post was not sent – check your email addresses! Through roads may only be situated outside urban areas. Over the past years the presence of avenues diminished heavily.

More information on the design of through roads can be found in the CROW publications on this topic [5] [6]. More readings and links: Apart from the sideways slope, the cross-section and revetment are also important. At the level of road design: This is important because a high, steep dike creates a different spatial effect handblek, say, a gently sloping wide dike. In principle, an intersection between a distributor road and a through road is grade separated.

Principles for safe road design

And is the tree, which is standing on the same spot in all cases the most guilty party or do other factors, not at the least the way people drive, play a much more decisive role? Notify me of new comments via email.

In a possible lawsuit, the road authority must be able to motivate why the guidelines were not complied with. Dike patterns also make the history of reclamation in the polder readable: More information on the design of distributor roads can be found in the CROW publications on this topic [7] [5].


ProMeV, proactively measuring road safety, uses a combination of four of the methods described above: Trees contribute of course in the production of oxygen trees are most effective when they are a little olderare cooling the air in the summer and reduce wind and storms and make people more relaxed.

More information on the design of access roads can be found in the CROW publications on this topic [7] [5]. Would you like to cite this fact sheet?

Cutting Trees a Solution? Which road categories are distinguished in the Netherlands?

Pedestrians and cyclists in residential areas therefore encounter wwgontwerp motorized traffic; this increases safety [3]. We need all the help —however small- to make it to our climate goal targets and every tree is helping.

To find out more, including how to control cookies, see here: The deviation of a chosen route relative to the desired route diagram, determines the extent of assumed unsafety.

Like the black lines that separate the pictures in a comic book, the dikes are the green lines that demarcate the Dutch landscape. There are several instruments that road authorities can commission to use to test the safety of their road network and their roads.

Less safe, but also often applied, is a cycle lane, separated from the lanes for motorized traffic by a broken or solid line. Some more restrained lobby groups politely wait some days or weeks till the formation of a new cabinet actually takes shape but one can recognize the real successful and accurate powerhouses by the swiftness they make their moves. The ring dikes mark the areas of reclaimed land that have lain low in the landscape since the sixteenth century. Intersections with and between motorways are always grade separated.


Road authorities Categorization of roads allows road authorities to ensure an efficient traffic flow in their management areas: The design disciplines are vital here: Seen from the car or bicycle, aspects of the landscape succeed one another like a cinematic experience, as we float above the landscape.

These guidelines are not binding; ultimately it is the road authority that decides on the road design. It is important that the entry ramp to a motorway can clearly be distinguished from the motorway exit ramp, to prevent wrong-way driving see also SWOV Fact sheet Wegpntwerp driving.

No doubt that every death or traffic injury is one to many and this should be prevented. ProMeV combines elements of different instruments.

Generally, the physical speed inhibitors are only used at intersections raised junction. Dikes make differences in the polder landscape legible: Each road category has its hanxboek design principles and characteristics: The actual implementation of the design guidelines is based on the Sustainable Safety concept and the Sustainable Safety-principles of functionality, homogeneity and predictability see also SWOV Fact sheet Sustainably safe road traffic.

In addition, the design of 2031 at transitions can be helpful in making road types recognizable.
