Abstract

In general the widths of pavements in channelized intersections, or junctions, must be sufficient to provide for the movement of 3 types of vehicles: The 50-ft. Semitrailer, the 35-ft. Bus, and the passenger car. Larger or smaller vehicles bay affect or control the width of some channels. The design of a channelized intersection is greatly facilitated by the use of vehicle models. A drawing of the intersection is made on a scale of 1 in. Equals 10 ft. The wheels of models of the controlling vehicles, also to a scale of 1 in. Equals 10 ft., are inked with a stamp pad and the widths and shapes of the wheel tracks traced on the drawing. The width of pavement required at any point may now be determined directly from the wheel tracks. The method is applicable to single-lane or multi-lane channels, and to all forms of curvature, simple, spiraled, compounded or reversing. Illustrations consist of drawings of controlling vehicles, photographs of principal models, and specimen applications of the method of design. An appendix shows the dimensions of a variety of vehicles with sketches of their characteristic wheel tracks on curves, and tables listing the maximum track widths which can be reached by the vehicles on turns, with the minimum width of pavement required after the maximum track width has been reached for any given radius of curve.
