Abstract |
A proposed model for classification of rural roads according to driver population characteristics is described. The driver population is distinguished by such traffic stream characteristics as trip purpose and trip length distribution, and the basic assumption made in the analysis is that the different traffic flow patterns observed at road sites result from different mixes of these characteristics. The highway systems of the provinces of Alberta and Saskatchewan are investigated for the purpose of developing and testing the model. The model suggests the application of some standard computational and statistical techniques to develop master patterns of traffic flow in order to recognize the driver population of a given road site. The proposed model is simple to apply and its data requirements can easily be satisfied by the types of data collection programs normally undertaken by highway agencies. Also, it is believed to be more objective and comprehensive than the existing methods used for the same purposes. The road classification resulting from the model could be used as an important criterion for many highway planning and design functions. Some examples of its application are (a) rationalization of provincewide traffic-counting programs, (b) design hourly volume considerations; (c) highway improvement programming; and, (d) highway capacity analysis.
