jtrrouter computes routes that may be used by sumo based on traffic volumes and junction turning ratios.
- Purpose: Building vehicle routes from demand definitions using junction turning percentages
- 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) a demand definition, see Demand Modelling
C) Junction turning definitions
-
- Output: Definition of Vehicles, Vehicle Types, and Routes usable by sumo
- Programming Language: C++
Usage Description#
jtrrouter is made for routing based on turn-ratios.
