rec.autos.simulators

Hi,

I am currently working on a program that will display split times in the
excellent racing sim Indycar Racing II.

I need to know how split times are measured in real life. Not how it
technically works but when does a car cross the ( imaginary ) line.

When his first tyre crossed the line ?
When both front tyres crossed the line ?
Or what ??

Thank in advance,

The time is measered when the black box crosses the line.  The black box
is located in exactly the same place on each car.

Which is to say: near the front of the sidepod -- driver's left, I think.

Only recently have they been in the same place for every car.  The margin
of victory for the 1992 Indianapolis 500, being the closest in history,
was adjusted later to compensate for the fact that one of the cars (Unser's
winning Galmer) had the box in the nose.  So the original margin of .06
seconds ended up being calculated as .04 seconds.

The possibility of one car out-boxing another suddenly seemed possible,
so it was decided all cars should have the transmitter in the same place.

If you want the real detail on exactly where the transmitter is, I'm sure
the folks at rec.autos.sport.indy can tell you.

I am NOT paranoid.  And why are you always watching me?!?

For ICR2 (or ICR1 or Nascar) the replay file defines the finish line
crossing as the point where the car's position on the track goes from
a high value (near the track length) to zero.

At 180 MPH, they are traveling 2.64 feet per second.

I guess they measured a difference of 5.28 feet of black box
difference?

They should have thought of that and made the rules up before the race
started.  Did they really go back and change history, or is the .04
figure just conversation trivia?

And on the front straight they're traveling considerably faster than that.

Good question.  Somewhere around here I've got a '94 Indy program...
It has margins of victory for all the 500s.

ah, here we are...  hmm... doesn't have margins, exactly, but has the
recorded race times of the top ten finishers:

 3 Al Unser, Jr., Valvoline                        12  3:43:05.148  134.477
15 Scott Goodyear, Mackenzie Financial Special     33  3:43:05.191  134.477

That's .043 margin of victory.

Here's the trivia question for the day -- no cheating, now...
Two other drivers finished that race on the lead lap.  Who were they?
