REGULARITY OF SOME DETECTOR-OBSERVED ARTERIAL TRAFFIC VOLUME CHARACTERISTICS
An extensive data base was obtained for four two-lane arterial locations in Toronto. The data was 5-mm detector counts in each base of each location for a total of 13,291 counts over 77 days. The paper reports on the regularity of the weekday pattern and of the time at which certain flow levels are reached. The patterns are quite regular, and the variance of the time at which specified peak levels are reached is rather small (from 4 to 6 min). A significant correlation between flows in the two lanes is found. particularly at higher volumes. The variation about the average pattern is also studied to assess the merits of using a predictor algorithm. The correlation between present and past variations (and thus future and present variations) is sometimes significant, but this correlation varies within a daily record. Further, it is not necessarily the same magnitude or sign at a given time on different days. It is nonetheless possible to construct a predictor that can extract information. The issue of the utility and the cost effectiveness of such prediction is noted, as is the fact that such an issue can only be resolved by considering the specific control with which the predictor is to be used. The issue of the typicalness or atypicalness of the Toronto regularity of pattern must also be considered.
