[D] Shrink or Compress data size

I have the following data structure:
ID, type x_coorde, y_coord, velocity, ... , speed, NG1,NG2.. NG9, lane.
the format looks like a two 2D Array

[
 [
  [1,1,0.9832,0.55,...,1,...0],[1,1,0.9832,0.55,...,2,...0],..., [1,1,0.9832,0.55,...,3,...0] (here are 9 arrays with 31 elements)
 ],
 [...],...[...] (39 million)
