4-way intersections: Throughput and deadlocks [image heavy]

[tsiebecker]

On incoming line from the north there is a wrong rail signal.

Should be fixed in Blueprint, Picture is faulty

You can, but not with RHD. Take mmmPI's layout, switch it to LHD, and you get full signalling.

Is there an analysis of how this compares with an ordinary LHD roundabout without the extra cross-tracks throught the middle of the circle?

Not that i know of, but it should yield pretty similar result to the "crossabout" vs "roundabout" shown in page 1. Given this is a smaller "crossabout".

Not analytically, no. Observational practice from emplacing the RHD version in my factory is that it has significantly better flow compared to the plain roundabout, and the LHD version should be further superior to that.
