TRAFFIC IN TORONTO. 2. DISTRIBUTION OF ROADS AND TRAFFIC

The paper first examines the supply of major roads which may be used for the purpose of satisfying some of the demand for journey-to-work trips in Toronto. Next the difficult task of predicting the distribution of journey-to-work trips over the road network is undertaken and is compared to the actual distribution of all trips over the road network. Finally, the variation of radial travel speed over the network is examined. It would appear that both the logarithm of traffic intensity and major road density decrease in proportion with the square root of the distance to the city centre. However, a superior prediction of the distribution of traffic intensity is afforded by the use of a trip density model incorporating basic urban travel parameters. The utility of continuous models was demonstrated in the case of Toronto by testing two assumptions. The first assumption, that the traffic carried by King's Highways 401 and 427 is primarily by-pass traffic, was confirmed. On the other hand it was shown that the location of the central business district south of the city centroid did not have a significant effect on traffic distribution. (TRRL)
