CAR SAFETY RESEARCH

Project 1: Driver response to potential loss of control situations: This will be tested by setting up on a test track situations enabling selected groups of drivers to be individually tested to ascertain: (A) their threshold of response to small disturbance of their vehicle's motion, or to small changes in their route which might not be pointed out to them; (B) their response to unexpected potential loss-of-control situations, in which they might not keep to a defined lane; (C) their threshold of panic or "freezing" to large disturbances to the motion of their vehicle (severe examples of (B) and the extent to which such responses are apparent). Project 2: "double-bottom" articulated vehicle simulations: to find design layouts which are most acceptable from a safety point of view with respect to: (A) the distribution of service and emergency of systems between the various axles; and (B) geometric layout, suspension stiffness relationships and loading restrictions. Project 3: the specification of cap tyre characteristics: to test the feasibility of describing about three broadly different types of tyre by a set of numbers, about six or seven in all representing eg tyre slip angles and lateral forces etc. At particular tyre conditions of load, state of wear, etc. Project 4: car with modified steering response: feasibility study of building into a car a system of modified steering response designed to overcome the tendency of drivers to apply excessive steering movement in response to situations which take them by surprise.
