I am trying to understand the flow of control in the source code of MITSIM Lab. One of the issues that I am having is understanding data structures used to represent vehicles and also identifying the programs that implement car following and lane changing logic. Main question is which folder contains source code that implements car following and lane changing logic. Does anybody have any knowledge about this ? In addition, it would be nice to if somebody can explain how controlo flows from one source file to another. Please let me know. Thank You !
