dfrouter ("detector flow router") uses induction loop values to compute vehicle routes that may be used by sumo.
- Purpose: Building vehicle routes from induction loop counts
- System: portable (Linux/Windows is tested); runs on command line
-
Input (mandatory):
A) a road network as generated via netconvert or netgenerate, see Building Networks
B) induction loop definitions
C) induction loop measures
- Output: Definition of Vehicles, Vehicle Types, and Routes usable by sumo
- Programming Language: C++
