Some traffic characteristics of Sydney

The distribution of homes and work places within Sydney is related to the distance from the city centre. Using a model presented by the author at the 7th ARRB conference in 1974, the distribution of traffic is predicted and compared with New South Wales Department of Main Roads data. Traffic intensity (distance travelled by all vehicles per unit area), travel speed, length of road per unit area, and the number of accidents per unit area are also related to the distance from the city centre. Other interrelationships between these traffic characteristics are discussed. The results may be useful in describing the macroscopic spatial relationships between land use and traffic.
