Road characteristics database-WKD/Leaderails

The Road Characteristics Database is a collection of databases each with a relevant road attribute

this can be linked to the national road stock (NWB).
These can be road characteristics

include, for example, the maximum speed, the width of the road or the presence of entry.

There is a separate file for each of these road features.

In this road characteristics database, the presence of guide rails in the middle m

recorded.

This is determined for road safety.
The narrower the middle broom, the easier a

vehicle can get on the wrong half of the road, with all the consequences.
In addition, it is also of

importance to identify whether other obstacles are present in the middle area, such as

guide rails, ditches or other objects that may prevent vehicles from running on the wrong

can come off halfway.

If there are guide rails in the middle bar, the width of this is not the

the middle broom is determined.
After all, the roads with a guide rail in the middle bar are already

protected.

Guide rails in the middle m are determined for roads with a maximum speed of 70 km/h

and higher and the roads must have separate lanes.
