What is an Typical Driver?

Post by brian »

Q: What is an Typical Driver?
A: A good starting point comes from a 1974 study "An Experimental Study of Automobile Driver Characteristics and Capabilities", Calspan Report No. ZQ-5208-K-1.
In that study the Average driver was defined as follows:
  • • Under familiar route conditions, the average driver utilizes maximum lateral accelerations of about. 3g in the speed range of 25 - 40 mph.
    • Under near-optimum operating conditions. (route familiarity. no other moving vehicles in the area, no solid roadside obstacles). The average driver is willing to utilize maximum lateral accelerations of about .4g in the speed range of 25 - 40 mph.
    • Assuming normal distributions, less than 20% of all drivers will exceed the above values by as much as.1g..
    • The average driver is willing to utilize full tractive acceleration capabilities of a vehicle and full braking capabilities of his vehicle in straight line paths.
    • A substantial percentage of drivers cannot satisfactorily control their vehicle under relatively mild skid - inducing situations.
See the Executive Summary from the Calspan report.
