THE CONTROL OF HIGHWAY INTERSECTIONS, ROUNDABOUTS AND SIGNALS. 14TH AUSTRALIAN TRANSPORT RESEARCH FORUM, PERTH 20-22 SEPTEMBER 1989; FORUM PAPERS. VOLUMES 1 AND 2

At a basic level, highway intersections are controlled by priority rules, that is one road is given priority over another. Right turning vehicles also give way to opposing traffic. Instead of numerical traffic volume warrants for installing signals or roundabouts, the paper suggests that delay, stopping and excess fuel consumption be determined for each intersection being considered for signals or roundabout control. Because fuel consumption considers delay and stopping, it should be minimised for the optimum form of control. An extension of the sidra program would be a convenient computing technique. In a numerical example, the excess fuel consumption for signal control was found to be relatively high. At isolated intersections this form of control should be used sparingly. Further work is required to determine the optimum extent of signal control in a network of intersections (a). For the covering record of the forum, see IRRD no 822808.
