-- occupation.lua
--[[
Collects and manages positions where trains occupy and/or reserve/require space
THIS SECTION ABOVE IS OUTDATED, look below
Zone diagram of a train:
|___| |___| --> Direction of travel
oo oo+oo oo
=|=======|===|===========|===|=======|===================|========|===
|SafetyB|CpB| Train |CpF|SafetyF| Brake |Aware |
[1] [2] [3] [4] [5] [6] [7] [8]
ID|Name |Desc
0 Free Zone that was occupied before, which has now been left
1 Train Zone where the train actually is.
2 SafetyB Safety zone behind the train. extends 4m
3 SafetyF Safety zone in front of the train. extends 4m
If a train is about to enter this zone, immediately brake it down to 2
4 CpB Backside coupling zone. If the coupling zones of 2 trains overlap, they can be coupled
5 CpF Frontside coupling zone
6 Brake Brake distance of the train. Extends to the point ~5 nodes in front
of the point where the train would stop if it would regularily brake now.
7 Aware Awareness zone. Extends 10-20 nodes beyond the Brake zone
Whenever any of the non-aware zones of other trains are detected here, the train will start to brake.
Table format:
occ[y][x][z] = {
[1] = train 1 id
[2] = train 1 ZoneID
// [3] = entry seqnum*
...
[2n-1] = train n id
[2n ] = train n ZoneID
// [3n-2] = train n id
// [3n-1] = train n ZoneID
// [3n ] = entry seqnum*
}
occ_chg[n] = {
pos = vector,
train_id,
old_val, (0 when entry did not exist before)
new_val, (0 when entry was deleted)
}
---------------------
It turned out that, especially for the TSS, some more, even overlapping zones are required.
Packing those into a data structure would just become a huge mess!
Instead, this occupation system will store the path indices of positions in the corresponding.
