Essential predictability features further developed [15]. Ontwikkeling van een systeem ter beoordeling van de veiligheid van fietsinfrastructuur. This is based on two main traffic functions of roads: The safety of a new road or a far-reaching redesign of a road can be tested in advance by carrying out a road safety audit in various phases of the planning and of the design see also archived SWOV Fact sheet The Road Safety Audit and Road Safety Inspection.

Categorization of roads allows road authorities to ensure an efficient traffic flow in their management areas: Testing existing roads Various tests can be used to test the safety of existing road infrastructure.

More information on the design of access roads can be found in the CROW publications on this topic [7] [5]. Make journeys as short as possible.

But degontwerp with incensed avenues and forests, like on the boarders of the Veluwe, are being appreciated higher than open, flat landscapes with few trees by tourists, visitors and owners. The cores method investigates whether the road network is structured in a logical fashion. In principle, intersections between trunk roads are also grade separated, but in practice this is not yet always the case. More information on the design of distributor roads can be found in the CROW publications on this topic [7] [5].

Michiel Pouderoijen, TU Delft. At intersections cyclists mix with car traffic and travel speeds of motorized traffic should therefore be lower than on the connecting road sections. Exposure to hazards and to traffic in general diminishes when requirements 2, 3 and 4 are complied with.


Also in the design phase choices must be made that will affect the wegonntwerp result.

With sufficient width the side strips on either side of the driving strip can be used by cyclists. Is it not the displacement of another problem?

Prevent obstacles at the side of the road. In the Netherlands, the predictability of roads is mainly executed by using markings that differ per road category.

Boom groot, plantertje dood! Figures Road length by road authority When a part of the city is restored, like Utrecht is doing, the process will take years. Each road type has its own zone indication; the markings have been developed per road type and can be applied in both urban and rural areas. Road sections If motorized traffic should be able to flow and travel at high speed, such as on the road sections of distributor roads, there must be a physical separation between the motorized traffic and cyclists.

Verschuure-Stuip, During the last six month, the discussion on the cutting off trees next to Dutch N-roads, provincial roads, was intensified. First and foremost, trees play a crucial role in the ecology and environmental issues of an area.

Preferably, the driving directions are physically separated by a median or by flaps, or else by a double solid line. Generally, the layout of trunk roads is less safe than that of motorways e.

Of course vegetation, land allotment and building development patterns also play an important role. Thus, if work is carried out on a dike attention must be paid not only to safety and multi-functionality but also to scenic beauty. Trees are contributing to the regional landscape identity and cultural history of the place and this should be an argument in the discussion as well.

Each road category has its own design principles and characteristics: Is the basis of the traffic problems this long row of beautiful trees or do we need to take a closer look at specific, dangerous spots? In this case the choice is generally customization, with thorough investigation of which compensatory measures are possible.


Here, too, the cross-section strongly affects spatial experience: What would happen if a yandboek of biking youngsters on the biking lane next to the road would be driven over because of the lack of a row of trees to safeguard them?

Over the past years the presence of avenues diminished heavily. Traffic safety is of great importance to us all. What are important safety principles for the design of access roads? At the level of routes: And is the tree, which is standing on the same spot in all cases the most guilty party or weglntwerp other factors, not at the least the way people drive, play a much more decisive role?

Access roads can be found in areas with a residential function. Whether a dike is revetted with stones or only with grass also plays a role.

Climate change

These markings have been applied on most roads. Access roads can be found in urban areas and in rural areas. The course, cross-section and revetment of the dike exert great influence on its spatial significance. The physical separation of driving direction applies to through roads as well as to both regional SW and national through roads SW Make sure that the concepts ‘shortest ride’ and ‘safest ride’ coincide.

This way road users will know what behaviour is expected of them, which other road users they can encounter and how these in all likelihood will behave predictability. Such roads are also called grey roads [8].

Wegoontwerp, many trees and avenues have hanrboek so much quality already.
