8 way roundabout
8 way roundabout 14×14
This will work with or without TMPE but here are some tips.
Lane connections —
Lets say were on a 2 lane segment coming into the merge. Left lane connects to 3 left lanes right lane connects to the 3 right lanes. Concept is 2 lanes merging into 6 lanes back to 2. Rinse and repeat 4 times
Junction restrictions —
Allow lane changing
Allow vehicles to enter a blocked junction
Remove Pedestrians crossing at the merge – Simple 2 lane roads so pedestrians can walk on them on default.
