A2021 Single Point Urban Interchange (S.P.U.I.)

This is a Single Point Urban Interchange or S.P.U.I.. It's a 'service interchange', connecting a highway to a regular road network.

This interchange has traffic from all four directions meet in the centre at a single intersection. Because of the additional ramps leading traffic to the right without having to cross this intersection, the traffic lights only have three steps in a full cycle (if properly set up). This interchange need some TLC from TM:PE. But if properly set up (follow screenshots) this interchange can handle lots of traffic!!

- Lane mathematics are applied for a good traffic flow.
- Lane connections have been applied.
- No clipping lightposts/streetlights (lights going through roads situated above them)

- As always; flatten the entire area the blueprint/template covers.
- Use TM:PE's 'Junction Restrictions' tool to remove crosswalks and allow through movements (see screenshots)
- I advise to put a 'Timed Traffic Light' on the intersections and set them up as shown in the screenshots.

Because '3-lane highways' are the most commonly used highway type on maps, I've created this interchange to be connected (the highway ends on the interchange) to these 3-lane highways. The 4th lane on the 4-lane highways are used as exit and entry lanes.

Note: I've used the mod called 'Road Options' to make the roads look darker. With this mod you can alter the road colors of all the roads in your city with ease. Link: https://steamcommunity.com/sharedfiles/filedetails/?id=932192868&searchtext=road+options

Enjoy!


Want to know how 'Lane mathemetics' work and how to use the functions of TM:PE? I recommend watching some of Biffa's traffic fixing video's on Youtube
