Timboh's Semi-Directional B-Trumpet Interchange

Mirrored Version: http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=411396977

More trumpets, Timboh? Do we really need more of these things? I'd say we do indeed need more of them. See, the semi-directional variant of the trumpet actually adds quite alot of functionality to the interchange. By widening and re-configuring some ramps layouts, two of the ramps actually gets priority over the other, improving traffic flow where traffic is heavier S <--> W, and lighter N <--> W. This design is pretty rare, though, but seem to be fairly common in The Netherlands.

======================================================================

Advantages:
+ Changed ramp layout improves traffic flow for two of the ramps
+ Still fairly easy to plop down, since there's only two bridges on the first level

Disadvantages:
- Changed ramp layout reduces capacity on the loop ramp
- Larger than the original trumpet

======================================================================

Cost: 24 880
Upkeep: 315 / week
