cityflow for irregular Intersection #160

Closed WaterFountain-Jack closed 1 year ago

WaterFountain-Jack commented 1 year ago

Hi, with the help of the CityFlow you wrote, I've been able to run some regular road networks, but I'm having some problems with things like five-fork or three-fork where I can't code Intersection by rules (Many operations of cityflow are generated according to the fixed position of Intersection on the grid), is there a possibility that cityflow can expand and irregular Intersection?

CityFlow support irregular intersections, you need to generate your own roadnet file as long as it conform to the format specified here

solution:

  1. write irregular Intersection by hands
  2. convert an irregular SUMO intersection into CityFlow format

CityFlow/tools/generate_grid_scenario.py can generate NxM grid road network with traffic flows(regular 4-fork).

I guess he/she wants to knoe is there a tool to generate irregular Intersection roadnet
