Joe quickly responded.
(Dean Sabatinelli is also a PhD, and has been timed TWICE
at over 269 MPH at Loring on an SGR Hayabusa)
Scott,
I have asked Dean Sabatinelli for assistance in this matter and
three PH.D's have been contacted. Their specialties include noise,
annoyance and information processing, coding for visual displays,
human vision, perception, and visual performance and transportation safety.
I have contacted various manufacturers who produce safety lighting.
We have identified that at the half mile mark the track goes downhill
for not quite a half mile and then becomes level again. The red placards
get muted by the white concrete. The track faces the southwest
and the afternoon sun becomes a factor also.
Things we have learned:
Flashing lights are the best for capturing attention.
Every onset and offset drives the visual system.
Flashing lights presented at 5-8 per second have
the best attention capture properties.
There are very few folks out there with photo-sensitive
epilepsy - about 500 people in the entire country. It comes
on at puberty, so they typically know that they know they have it.
The flash rates that trigger reactions are fast; 12-18 per second.

Dean: Sorry to have touched a raw nerve here, I was
just going by my interpretation of what Joe emailed to me.
I somehow assumed that the "group" of you had been
"engaged" to offer opinions either together, or individually.
I put "hired" in quotes, since I did not know if:
1) Money would change hands for consultation.
2) Professional opinions would be offered.
3) Written reports would be made.
4) Recommendations would be made, etc.
I was just going by what I read in Joe's email to me.
If I have mis-interpreted that, it's my fault, and I apologize....
Scott
