Tool for transport modeling for Apache Spark. The aim of the project is implement two step (Origin-Destination matrix estimation and Traffic assignment) of the four-step transport model. All algorithms are implement in Apache Spark environment, therefore it is possible to create a large models.
Framework provides following methods for the traffic assignment:
- All-or-nothing (AON)
- User equilibrium (TAP) - example code for this methods are in class com.kolovsky.example.TwoRoadAssignment
- Path based algorithm (Jayakrishnan 1994)
- B algorithm (Dial 2006) - limited parallelization
