The suggested speeds for each road class are stored in these INI-style files and can be edited with any text editor. They are primarily aimed at cars.

 

link.spd file can be used with RouteFinder 5-6, RW Net 4 and RW Studio 2.

 

Attributes

Codes for oneway restrictions and roundabouts are included in the attribute2 and attribute4 fields.

 

SkipInSearch in the attribute gets set according to the table above.

If you want to use a network with paths for car traffic too, you may manually set bit SkipInSearch (add 32768) for roadclass 18.

 

RouteFinder 5-6, RW Net 4, RW Studio, FleetEngine

In attribute4 the hierarchy bits has been set, according to this table (field RouteHierarchy):

 

1: Motorway, A Road Primary, B Road Primary & Ferries

2: A Road

3: B Road

4: Minor Road

5: The rest

 

We have not yet tested if it works well with the routing hierarchy function.

Hierarchy for ferries is set to 1, but will need to be set to the neighbor links to work correctly.

 

"AvoidPattern" field has the content of the NoWalking and NoDriving bits.

 

RouteFinder 3-4, RW Net 2, RW NetServer 3

In attribute2 field, you get these 4 modes as part of the field setup instead of the hierarchy bits:

 

Mode 1: Pedestrians / bicycles

Mode 2: Cars

Mode 3: Not used

Mode 4: Not used
