New Kyoto layout for current roundabout

[Marty_Deslions]

The current layout at Kyoto has a small roundabout in it. It connects traffic coming from and to the spawn/SOS station, the autobahn south and north, and the infield (or whatever it's called).



However, I think the current design is abit cramped and abit too complicated, and it could be improved and simplified. Not only does the current roundabout take the traffic flow of the autobahn away (you'll have to slow down to at least 60 kmh, even if you take the bridge), it is also abit too tight for comfortable driving with bigger vehicles like busses or trucks.

I give you 3 concepts to improve this intersection.



Concept 1: "USA Style" intersections







I removed the roundabout as a whole, leaving nice open roads in return. There are two intersections with trafficlight. The speedlimit on the autobahn parts around these two intersections should be 100 kmh, as can be seen on the signs. I like the idea of using the lines on the road that are fixed on the map.

The trafficlight cycles should have two phases.
Phase one: Traffic on the autobahn has green light, the two side roads (from main spawn and from infield) have red light.
Phase two: the autobahn has red light, the two side roads have green light.
I'm suggesting phase one will be on longer than phase two. Maybe lets say 15 or 20 seconds for phase one, and 10 seconds for phase two.

Behind the yellow wall there is room for parking or some building or whatever.


"Man, this design is dangerous, and somepeople will just fly through both intersections, creating big crashes."

Well, if that happens, that player obviously doesn't care too much about the traffic rules (speed and maybe redlight), and if he then causes a crash, he should apologize. If he doesn't, maybe report. It's basicly the same with any other traffic intersection on TC.

Side note: To enforce the speedlimit of 100 kmh around these intersections, they could be a permanent speedtrap, if that can be build in the insim.

Concept 2: Bigger roundabout









With this concept, I kept the idea of a roundabout, only I made it bigger. Not only that, but there is also more room to navigate around it. First I created 2 lanes on the roundabout itself, which looked fine in freecam mode, but driving there felt abit cramped, so I got rid it of those lines. Now it's just a 1 lane wide roundabout. The whole intersection is now simpler than the current roundabout situation on TC. I've kept the bridge as it is. Next to the busstop there was a pitstop/fuel station on the grass. I removed that, and I've returned it under the bridge part. At the end of the bridge I placed down some lines and arrows, that direct traffic onto the autobahn, instead of the buslane/emergency lane.

Concept 3: Overpass with off and on ramps

The idea of this one is to create an overpass, just like the other overpass on the AB:


An advantage of this is that the speedlimit AB can be 160 kmh all around. A disadvantage may be the large number of objects. Not only that, but the on and off ramps also may be abit tight, just like the other overpass situation. This is due to a lane being split into a right autobahn lane going straight, and the off/on ramp. A solution for this would be to sacrifice the whole right/outer lane to be the off/on ramp, leaving only the left/middle lane for traffic going straight on the AB.
Abit like this:
