NetPrep – New Concepts  Local-Thru segment length –Assigns local streets to the new Local-Thru facility type based on the length of a series of local links  Local selection spacing –Selects representative local streets from an all-streets network for inclusion in the TRANSIMS network  Drop dead end and short links –Links less than length value are dropped  Split large loops –Loops (anode=bnode) will be split into two links to permit loading 1/20/2011 Chicago RTSTEP TRANSIMS Model 6

Collapse Divided Arterials  GIS often includes parallel links for divided arterials  Complicates TRANSIMS coding and simulation of signalized intersections –Version 5 can model multi-node signals, but the network will be easier to edit and the simulate if a single node is used The DIVIDED field in the link file models link access like parallel roadways 1/20/2011 Chicago RTSTEP TRANSIMS Model 7 
