Belgium is amongst few artificial countries, established on purpose, when
Dutch and French speaking parts were joined in a single unit. This makes
Belgium a particularly interesting testbed for studying bio-inspired techniques
for simulation and analysis of vehicular transport networks. We imitate growth
and formation of a transport network between major urban areas in Belgium using
the acellular slime mould Physarum polycephalum. We represent the urban areas
with the sources of nutrients. The slime mould spans the sources of nutrients
with a network of protoplasmic tubes. The protoplasmic tubes represent the
motorways. In an experimental laboratory analysis we compare the motorway
network approximated by P. polycephalum and the man-made motorway network of
Belgium. We evaluate the efficiency of the slime mould network and the motorway
network using proximity graphs
