Future Plan: Turning-ratio-based vehicle routing mode

[toruseo]

Currently, vehicle routing is based on route choice between OD pair, which is suitable for trip-based analysis.

Another common routing rule is based on given turning-ratio at each node (constant or variable). In this mode, vehicles do not go to their destination; they circulate the network indefinitely by following Markov process. This will be suitable for specific theoretical analyses and data-driven analyses like travel time prediction and traffic state estimation. The former might be more interesting as existing common traffic simulators are not suitable for such purposes, to my knowledge.

Hopefully I can start working on December.
