Typical driving patterns
Typical driving patterns
(OP)
Does anyone have some data regarding the typical driving habits of people for:
1. lateral acceleration
2. steering angle (at the road wheel)
3. vehicle speed
4. and how do the above change with geographical area, type of vehicle?
This data would be good in deciding upto what limit a math. model of a vehicle needs to be validated.
A paper titled "Uneven wear of vehicle tires" (Tire Science Technology) Vol 21. No.4 Oct-Dec 1993 has some of this data. I'm not able been able to get a hold of that paper from the library.

2, there's quite a lot up to 10 degrees, then not much until you hit full lock
3 yes but I can't tell you exactly. Basically in Australia everyone drives either at the speed limit or 10 kpgh below it. Our most common speed limits are 60 and 100 kph.
4 don't know.
There's an SAE paper on tire wear on a truck with different camber settings, that has some relevant data.

I was going to argue with you about Australians driving at or below the speed limit, but on reflection you are right. If I set the cruise control 5km/h over the limit on motorways, I pass a lot a lot of cars, and not many pass me.
Of course Pat described his driving philosophy a few months ago. He might shift the average.

3. Traffic volume and enforcement absence permitting, speeds in much of the northeastern US tend to run 5 - 8 mph above posted for secondary highways (posted at 45 - 55 mph) and 5 - 15 mph above the 55 - 65 mph Interstate postings.
