Compact Underpass & Roundabout (CURB)
CURB by XIRI:
A compact underpass and roundabout combination designed for a much better traffic flow on X-intersections. Also works for T-intersections!
Features:
*Better management of heavy traffic, especially if most of it is travelling in one direction.
*Takes up practically no space at all! (compared to larger full roundabouts)
*Tested traffic flow: >150 vehicles/min per lane!
*Easily customisable to your city!
To have the CURB working as intended, use TM:PE to indicate the traffic flow lines!!
Bare minimum to work properly: remove traffic lights, add priority signs.
Shown in the images are two examples, one is the most simple version of this intersection when placed down, one is an adjusted version I used in one of my cities. Note that flow lines are always ignoring the tunnel, this should only be used by traffic going straight ahead! (for flow reasons)
For optimal customisability of the roads (especially the underpass part), use this mod:
Simply move away the two tunnel nodes temporarily to change the center avenue or the tunnel!
