Structure

List of records of the form:

DWORD       Unknown (always 0)
BYTE        Appearance flag (e.g. 0x10, 0x11, 0x14 or 0x15)
DWORD       Record type identifier (always 0xc7cc75f1)
BYTE×4      (Min Tract X, Min Tract Z, Max Tract X, Max Tract Z) coordinate

DWORD       Unknown (always 0)
DWORD       Address
    DWORD       Subfile (Automata Attractor subfile) when Address is not 0
FLOAT32×5   Unknown (the last three are 0.0 if the attractor is absent, so might be related parameters)
DWORD       Address
    DWORD       Subfile (e.g. Trailer Vehicle, Ambulance, Bus, Patrol Car) when Address is not 0

    DWORD       Unknown (seen 0, 7, 13)
    WORD        Unknown (always 0x03)
    DWORD       Address
        DWORD       Subfile (Automata Generator or Attractor subfile) when Address is not 0
    DWORD       Index of block starting at 0, 1,...
    FLOAT32     Unknown (-1.0 or large numerical values)
    DWORD       Unknown (0 or 1)
    BYTES×5     Unknown (always 0)
    DWORD       Unknown bitset
DWORD       Count of auxiliary models
    DWORD×3     TGI of auxiliary S3D-model (e.g. head lights, rear lights)
DWORD×3     TGI of S3D-model
DWORD       Instance ID
DWORD       Count of manager addresses
    DWORD       Address
    DWORD       Subfile (e.g. City Situation Manager or Automata Controller Manager)
FLOAT32         Speed in km/s (can differ from other speeds)
FLOAT32         Speed in km/s (can differ from other speeds)
FLOAT32×6       Unknown (often 0 or 1, but numerical values are possible)
BYTE            Unknown (seen 0, 25, 50, 254)
DWORD           Occupant Group
DWORD           Address
    DWORD           Subfile (e.g. Trailer Vehicle, Ambulance, Bus, Patrol Car) when Address is not 0
DWORD           Unknown (seen 1, 3, 7)
BYTE            Unknown (in range 0...47 -- maybe vehicle lifespan?)
DWORD           Address of network tile
    DWORD           Subfile (e.g. Network Subfile 1, Prebuilt Network Subfile, Bridge Subfile) when Address is not 0
BYTE            Exit side of path (0,1,2,3 = W,N,E,S)
BYTE            Entry side of path (0,1,2,3 = W,N,E,S)
BYTE            Path class number
BYTE            Unknown (presumably Path Transport Type, i.e. 0x01 for vehicles)
DWORD           Unknown (seen 0...40 -- smaller values are much more frequent)
DWORD           Count of blocks to follow
    BYTE×3          Unknown (seen for Occupant Group Moving Van)
DWORD×2         Unknown (always 0)
FLOAT32×3       (x, y, z)-coordinate C or (-1, -2, -3)
