Traffic flow simulated on 30 different kinds of 4-way junctions

Here’s a really fascinating animation and analysis of traffic flows with different intersection methodologies. More interesting is that they were done with off-the-shelf steam games/tools found on Steam. I think

Some interesting observations:

  • 4 way intersections with lights (235 cars/min) is only slightly better than a no light free-for-all (191 car/min)
  • Standard roundabouts with stops are really horrible, but get pretty interesting and good with a few simple improvements
  • There’s a lot of interesting junction/interchange types I’ve never seen before
