ROAD COURSE PROFILES

[CESSNA1]

HELLO ALL: Vehicle road testing can be done over predefined road profiles. The Perryman Profiles are often used. I am trying to find the definition of the Perryman Profiles. Does anyone have the profiles for the Perryman 1,2,3,4 road courses? I have searched the internet and have been unable to find them.

Thank Vou Very Much

Dave

Should have searched for Perryman Road Profiles.

Seems to me the best bet would be to contact NATC and see if they can sell you them, or get your customer to supply them.

CLOA AND GREG: Thank you for the your time and effort to respond, I sincerely appreciate it. The website listed by Cloa does not give the level of definiiton for which I am looking. For example is the profile flat or sinusoidal or somewhere in between. Greg, I did Email NATC asking for this information and they ignored me.

There should be apublication somewhere that defines these courses and their profile. That would be very good - if it exists.

Guys - Thank you again for your time and effort.

Cordially
Dave

So what sort of precision do you need? In my section we routinely measure road profiles to an accuracy and resolution of the order of mm, whereas other people might just need grades and so on. Since those tracks appear to be soil or sand I'm fairly sure you don't need 1mm accuracy.

GREG: You are correct, I do not need 1 mm accuracy. The name "PERRYMAN" implies that the course is defined, perhaps in a spec, or std, or some other document. I realize that the "actual course" and the "defined course" can, and probably vary. I just want to find out how the course is defined.

Thanks for you interest, time and effort

Keep looking. You might want to start with:

Their PDFs have some good information about standard test track profiles.

The other place is THE source, i.e., Aberdeen Test Facility:

While they don't have the specifics on their website, they might email you the information.
