Detailed Description

Translates emme networks into matsim networks.

Uses the "emme network export" result as input, NOT the GIS export.

A serious problem is that there is not enough info in the headers of the emme files: (column counting starts at 0!!!)

link "length" (column # 3) is in arbitrary units, connected to rest of system only through freespeed value
Column # 8-10 are user-defined BUT contain freespeed, capacity, ... in arbitrary order and units (connected to rest of system through user-defined volume-delay functions)

Keyword(s): emme/2

I moved this here because in this way it can be html-referenced out of matsim.org. Additional code that does similar things can be found by searching the playground for "emme/2". kai, mar'11
