For example, since the late 1950s a stream of Recording Secretary / Secrétaire d'assemblée Rod H. Packwood, P.

Phys. flow in a traffic jam. Somewhere between these two limits lies the maximum Institute for Microstructural Sciences National Research Council (M-36) number of cars for maximum rate of flow. For a start, it transpires that the Montreal Rd., Ottawa, Ontario Kl A 0R6 average driver takes no notice of another vehicle more than 60 metres in front (613) 993-9614; Fax: (613) 993-6486 e-mail: [email protected] of him or her. For shorter distances the driver responds to the car in front Henry P. Schreimer and generates an induced response by a car behind. As a result there is a School of Information Technology and Engineering minimum distance between cars necessary to ensure that no collisions occur, University of Ottawa, 800 King Edward Ave., Room 3-034 Ottawa, Ontario Kl N 6N5 in which case optimum conditions occur and can be predicted!
