3-Level Inverted SPUI
The 3-Level Inverted SPUI can handle large amount of on-off highway and traveling through main road traffic. There is no intersection when go straight through the main road.
To achieve higher efficiency, I recommend to upgrade the on-off highway ramp and the ground-level main road into 4L road from Network Extension 2 Mod .
Traffic management you need to do to make it function well:
- Remove the traffic light and set up lane management of the intersection at each end of the main road.
- Make sure the middle intersection have traffic light and can only turn left and right for all 4 directions.
- Remove pedestrians crossing from all intersection
