PRELIMINARY INVESTIGATION OF MOVEMENT TIME BETWEEN BRAKE AND ACCELERATOR PEDALS IN AUTOMOBILES

Results of preliminary study to determine if there is valid cause to question positional relationship of brake and accelerator pedals in contemporary automobiles; teh subjects were tested to determine how long it akes to move foot from accelerator to brake pedal in same horizontal plane, and with 6 in. height differential; experimental results indicated that at high speeds, reduction in stopping distance of upwards of 14 ft could be affected for case tested. 0282 13-87- 150- 230 EI 70 /HUMAN ENGINEERING/ /AUTOMOBILE DRIVERS/ CEMENT Manufacture Uuse of grinding aids in cement grinding, (Ueber die Verwendung von Mahlhilfen bei der Zementmahlung); H.
