What was wrong with the street circuit

Nice circuit, and looks like (from the aerial view) it has a similar feel to many of the other French circuits. Good one.

[SpeedingTortoise]

Theres nothing wrong with the street circuit, but its not going to attract F1 or DTM and the likes.

[ScotsBrutesFan]

You have clearly spent a lot of time and effort on this, at times I feel your bid to include terrain into the overall design is to the detriment of circuit itself.

Don't get me wrong most of your circuits are great when seen on top view (2D if you will) but I personally don't believe that Sketch-up can do the terrain details that you require and envisage justice.

Can you tell me when doing a circuit such as Pyrenees, do you have a circuit plan before you add elevation, or elevation map in mind to then add a circuit, or all at the same time ?

[SpeedingTortoise]

I agree, sketchup isn't the best when it comes to making terrain but its all I can use just now and Id rather put the effort in and have the surrounding terrain than to leave it blank. I believe it adds more atmosphere to the pictures and shows the viewer my idea better.

To answer your question, I usually have an idea of elevation before I make the circuit in general. The general idea behind this one was I wanted to have a track that went to one area and then back, almost mirroring the first half of the track but with elevation between the two sides. Salzburgring was the inspiration behind it but I wanted to take that concept onto a bigger scale.

When I start to make track like this I always make it in 2D to start with. Most details are included in this such as gravel traps, space for pit buildings etc. Stands aren't made in this as they can be adapted onto the elevation if they need to be. The track is then split into 3 sections: floor, slope and elevated track. A fourth section around the exterior of the track can sometimes be created if im making a circuit that is located in a valley, such as this one. The elevated parts are simply extruded up to the preferred height. A smooth, transitional 2D slope is created near the soon to be uphill/downhill piece of track. This 2D slope is pulled using the follow me tool over the track. The transitional pieces of track are then extruded through the slope and then intersected with each other. The excess slope and extrusions are deleted. The same process is done for any other elevations. The terrain is then filled in between the elevated track, the floor and the transitional track using the sandbox tool. Any terrain that is added to the exterior of the track is simply a triangle that has followed a path to create a basic slope. these are layered on top of each other to create a basic hill. The 3D details are then added to the track eg barriers, stands and garages.

I decided to revise the infield of my 2nd Stadium circuit as after uploading it I still thought that it wasn't developed enough and could be better. The new infield manages to increase the circuit length by over 0.5mi and gives the drivers a more challenging circuit while letting the spectators a better chance to see the cars.

[ScotsBrutesFan]

I'd propose a very sight change to the pit exit. I know this one is Canada-esque, but I'm not a fan of that one in the real world either.

The changes are simply to have the joining cars pointing in roughly the same direction as the track, with the use of the Don't cross line to keep the cars from diving straight onto the racing line. Descriptions are below but as always a picture makes things a little clearer I hope.

Option one
Have the end of the pit lane mirror the chicane slightly on the infield so that the joining cars are moving in the same direction but held on the outside of the corner



Option two
I don't think that there is a need for that much gravel on the outside, so instead, run the pit exit around the shape of the corner, joining on the outside but using the width of the pit exit to widen the rejoin point with the don't cross line. Where the circuit briefly runs parallel a double sided kerb that gradually flattens out could be used. The outer edge of the pit exit smooths into he outside of the circuit further around.

[LuiggiSpeed]

I see your point SBF and I have to say I thought roughly the same as you, you nailed both good points to enter the track, I was just thinking if it wouldn't be better to join before the turn itself, like at the apex from the right corner?

[SKG]

I like 2nd option better. Maybe a Nurburgring-type raised kerb or some bollards separating the track and the pit exit?

[SpeedingTortoise]

A Grade 2 track built at Podgorica's former airport. Since the airport is still in use although not for commercial flights, the track has been designed so that the facility can switch between racing and flying without almost any preparation time or cost.

Grand Prix 3.11mi | Short 2.11mi | GP chicane +0.01mi | Bus Stop chicane +0.03mi | All layouts clockwise

[ScotsBrutesFan]

Or anticlockwise as drawn

It's a nice variation on an airport circuit.

Yeah. No idea why i put clockwise.

[SpeedingTortoise]

A 2.24mi Speedway with a 4.04mi Road Course built to attract NASCAR and Indycar to the Canadian west coast. The oval has 10° banking on the straights and progressive banking of 10°-30° on all 3 turns. There is also a short 100m straight between Turns 2 and 3 (with the progressive banking) to individualise it from other egg shaped ovals. The road courses don't use any part of the banking making them suitable for bikes.

Oval and GP Anti Clockwise| Short Clockwise

[SpeedingTortoise]

A 2.85mi street circuit based around Botafogo Beach and giving it a 'Monaco of South America' feel. It is designed to host Brazilian Stock Cars and other South American series. The track is long enough for F1 and other international series but would depend on pit facilities.

2.85mi | Clockwise | Average Width - 13m | Narrowest - 9m (Exit Turn 4) | Widest - 22.5m (Entry Turn 6)

quite like that...how much space is there between the track going both directions in the middle though (Turn 7 i think)? I guess the cars probably wouldn't be so fast coming out of the hairpin, but still...no runoff, with another part of the track going the opposite directly behind it could be a safety issue...

[SpeedingTortoise]

There is 3.3m between the two parts of track at Turn 7. The run out between Turn 6 and 7 is only 105m so I think cars won't be going too fast for safety to be an issue, however there would be a tyre or tecpro barrier on the outside of the corner. I also don't think there is the space or the need for the corner to be a chicane. A small advantage is that at Turn 7 the track is above average width at 16m so there is space there if needed.

[SKG]

Hey, this is great! Two tricky areas for me. Turn 7 (like mentioned above) and turn 9 (the long right before the top hairpin).

As for turn 7, it's difficult to judge how fast it is. I initially thought it was a tabac-esque turn, then realised the corner was much more open. The track looks wider too. I'd definitely say that tecpro barriers would be more appropriate than tires here, three layers probably.

Turn 9 looks like just a tricky part of the circuit, there isn't really an alternative. The most challenging braking zone on the circuit?

[SpeedingTortoise]

I thought Turn 7 would be like the first turn/kink at Pau. I think it would be flat in formula cars and maybe a slight lift for touring cars and GTs.

Originally Turn 9 was going to be much longer and be the start to a section similar to the Massenet/Casino/Mirabeau section at Monaco. The hairpin would've been a chicane but I decided against this layout as even though I think this section would have been great to drive, there wouldn't have been a good overtaking spot and would have added another chicane to the circuit. It would also have made the track 3.14mi long.

I think you made the right call, this circuit doesn't need another chicane!

A 2.15mi temporary track based around Aloha Stadium in Honolulu, Hawaii. Designed to host Indycar racing and TUSC.

2.15mi | Anti-clockwise | Average Width 12.1m | Narrowest 9m (between T10 and T11) | Widest 14.5m (between T15 and T16)

[SpeedingTortoise]

A massive motorsports complex south of Rotterdam, Netherlands featuring 4 Grade 1 circuits connected to create 3 endurance layouts, a 0.90mi banked oval and a 1/4 mile drag strip.

Full track length 14.30mi | Track width 13m | Oval width 18m | All Road Courses Clockwise | East hosts F1 and MotoGP | South hosts DTM, Indycar and GTs | West hosts WTCC | Full hosts WEC

[SpeedingTortoise]

Individual layouts.

[ScotsBrutesFan]

How big is the combined East and West Endurance circuits, also what is the dimensions of the area that you have used?

Comments on further study

[SpeedingTortoise]

The length of the longest, combined track is 14.30mi. The island is around 7km/4.3mi long by 2km/1.25mi wide at its widest points.

[SKG]

Wow! Imagine the planning permission....

I like the West Endurance (turns 1, 2, 3 would be an experience) and North circuit configurations.

[The IC]

heh, you could have some smaller race series run their whole championship without ever having to leave the island!
