Which is more common around the world, Clock Wise or Counter Clock Wise road racing courses?

VIR - CW
Roebling - CW
CMP - CW
Lowes - CCW
Rockingham - CCW

Daytona - CCW?
Sebring?
Watkins Glen?
Le Mans?
Silverstone?
Riverside?

Are NASCAR roundy rounds CCW while most everything else is CW?

Sebring, Watkins Glen, Le Mans & Riverside are/were all clockwise, but Laguna Seca is counter-clockwise. Most North American road racing courses are clockwise (including the Indy GP circuit.) Most of the rovals are counter clockwise to enable use of the existing safety set ups and support situations.

Bremerton=CCW
Thunderhill=BW
Sears=CW

Buttonwillow= BW
Laguna= CCW
Fontana =CCW
Willow springs= CW but looks like it could go both ways
Spokane=CCW
 
Gateway -- CCW
Memphis -- CW
Hallett -- CCW (although we used to run CW also)
Topeka -- CCW
Mid-America -- CW
Hastings -- ??
 
Texas World speedway 2.9 CCW
Texas World Speedway 1.8 both CW and CCW

Motorports Ranch Houston 2.4 CCW
Texas Motor Speedway roval 2.4 CCW
 
nelson ledges--CW (ages ago was occassionally run CCW)
Beaverrun--CW
Mosport-CW

I think we inherit CW for road racing from European roots.
 
Mid-Ohio - CW
ORP road course - CW, oval - CCW, drag strip -(if you have to be told, you're too young to drive!)
 
A interesting measure of a closed track might be the total degrees of CW or CCW.

For example a CCW oval is obviously 360 degrees CCW. But on a twisty road track you have both CW and CCW turns. So Laguna is CCW but how do the turns add up?

360 degrees, of course. One direction is positive, the other direction is negative... :)

What I think you're actually looking for is how many degrees (or radians) of CHANGE there is per track. However, when trying to use that as a standard for whether a track is twisty or not, probably an average rate of change per mile is more appropriate. - GA

Yeah, that's the ticket!
 
Blackhawk - CW
Gingerman - CW (does run CCW at some track days)
Autobahn - CW
Road America - CW
 
Doesn't that add up to "zero" ?[/b]

No, 'cause then you'd end up continuing in a straight line away from where you started, not to. Since you end up in back the same spot, it's 360 degrees...uh, right?
 
Barber Motorsports (Birmingham) = CW
Memphis Motorsports Park = CW
Road Atlanta = CW
Roebling Road = CW
Carolina Motorsports = CW
Nashville Super Speedway Infield Course = CCW

So...you're only dealing in absolute values. Gotcha. What about all those additional rotations, and what about all those times when I enter corners 'forward', but exit them 'backwards' (sometimes using the CW method...sometimes the CCW method), and then have to pick a direction to navigate back to 'forward' again ?

Well for you, John, anything between 361 and 1079 degrees is acceptable...

Should we address axial rotation values/limits for John too since he seems to be on a roll......
