Section 1a contains the nodes for vehicles, section 1b contains the nodes for peds
Link ID is an index to entries in section 3,5 and 6.
Area ID is the area of the node, the same as in the filename.
Node ID is used to refer to nodes in the other sections.
Node type is some kind of group for the nodes, in section 1a is 1 for cars, 2 for boats and higher values for race tracks and other mission-stuff. For peds there's a node type per village/city.
