Overview

This seems to provide routing information within the world. The data for the entire map is broken up into small blocks.

Header/index

DWORD version 1
DWORD count1
DWORD count2
REP count1 x count2
    DWORD offset from the end of this list to the route block location
REP count1 x count2
    -- route block

Route block

WORD vertex count
REP vertex count
    WORD offset from the end of this list to vertex data
REP vertex count
    BYTE path count
    BYTE usage
    BYTE X position (Within this block)
    BYTE Y position (Within this block) 
    REP path count
        BYTE destination vertex (Index to vertex within the destination block)
        BYTE destination block (Relative)
    REP path count
        BYTE path type

Each point defines a vertex in a graph of route information. Several different route types are used, as defined in the vertex data. The bulk of the routes are type 7, which forms a mesh over most of the area sims can get to. However it is unclear what it is actually used for.

The destination block defines which block the path ends in relative to the current block.

For example, 108 (01101100) means it is in the same block, 80 (01010000) means it is north-east one block. Paths are symmetrical, so the destination vertex has an identical path going the other direction.
