EXPLORING THE MECHANISM GOVERNING THE RELATIVE USE OF MAJOR AND MINOR ROADS IN URBAN AREAS

This paper describes some of the factors affecting the relative use of major and minor roads by utilizing a simple model with an analytical solution. The model presented here represents a typical urban area as a grid system of roads of fixed total length with a fixed total number of vehicle kilometres travelled in the area. When a given percentage of the total road is major road, the amount of traffic that uses the major road is determined by using Wardrop's first principle, i.e. Equal travel times on both major and minor roads, except when it is always advantageous to travel solely on either the major or minor roads. Major and minor roads are described by their travel time characteristics, simplications are necessary but the mechanism by which an equilibrium is established between the use of major and minor roads is sufficiently described.
