This compilation is based upon Meridian 2 files from Jan 2014 (Meridian 2 v1.2 Release 1 2014).

It contains the files from these SHP files, merged together as a single layer:
(1) Motorway
(2) Trunk (selected from A_roads marked by field "trunk_indicator")
(3) A_road
(4) B_road
(5) Minor_rd
(9) Ferry - added by RouteWare from 1:250,000 raster maps

() = road class, which can be used for assigning different road speeds.
Suggestion:
(1): 70 mi/h
(2): 55 mi/h
(3): 50 mi/h
(4): 40 mi/h
(5): 25 mi/h
(9): 15 mi/h

You can further refine this by using the field "Urban" (0/1) for reduced speed in urban areas.
(based upon dlua.tab)

Z-level information from roadnode table has been attached to the polyline records.
Using this information when building the road network prevents "jumping" off bridges
to roads below, but also introduces errors, since the level is simply wrong in many places.
We do NOT recommend using Z-level information until the quality of the data has become better.

We have corrected a few "snap" errors and also corrected a few object errors.
Loop links has been split into 2.
Subnets has been deleted from the table. Mostly a few smaller islands.
