Ver. 1.1 Town growth simulator that creates road networks.
Outputs a text file which contains lists of roads, and if the road is curved, a list of its turning points.
See paper here.
See presentation slides here.
Below are examples of the expressive range exposed by some of the parameters.
Use -h for up-to-date commandline options. Do not use --noui; it is out of sync.
usage: graph.py [-h] [--noui] [-o OUTPUT] [-s SIZE] [-c CYCLES] [-p2 PHASE2] [-p3 PHASE3] [-ma MAJOR] [-mi MINOR] [-by BYPASS] [-br BRIDGES] optional arguments: -h, --help show this help message and exit --noui Suppresses UI if set. -o OUTPUT, --output OUTPUT Output file name. Default: output.txt. -s SIZE, --size SIZE n for nxn grid. Default: 200. -c CYCLES, --cycles CYCLES The number of full cycles to run before ending simulation in commandline. The simulation does not self-terminate when running in UI. Default: 15. -p2 PHASE2, --phase2 PHASE2 Minimum total prosperity to allow calculation for bypass roads. Default: 200000. -p3 PHASE3, --phase3 PHASE3 Minimum total prosperity to allow calculation for minor roads. Default: 80000. -ma MAJOR, --major MAJOR Minimum local prosperity for a new major road. Default: 10. -mi MINOR, --minor MINOR Minimum local prosperity for a new minor road. Default: 400. -by BYPASS, --bypass BYPASS Minimum local traffic for a new bypass segment. Default: 2000. -br BRIDGES, --bridges BRIDGES Minimum local prosperity for a new bridge. Default: 5000. We mirror-forked SUMO here allowing the town-sim output to be piped into the SUMO format (.net.xml): https://github.com/julinas/sumo-mirror making some minor changes to SUMO's netgenerate program. Edited files are netgen/NGEdge.* , netgen/NGNet.* , and netgen/NGFrame.*
This is the added usage where filename1 should be the location of the file generated by town-sim-py and filename2 is the output location of the resulting .net.xml file.
netgenerate --town-sim --town-sim.file=[filename1] --output-file=[filename2] Ex.
netgenerate --town-sim --town-sim.file="output.txt" --output-file="NewSUMOFile.net.xml" The output function is set up such that the lists of road nodes and segments can be messed up if outputting twice in one simulation.
