Abstract | Traffic simulation techniques are standard tools to analyze complex traffic networks. In dealing with large urban networks, the macroscopic approach to simulation is much favored over the microscopic approach due to its low computational requirements and simple usage of macroscopic models. Macroscopic models, however, have difficulty in defining movements in areas where the interaction of individual vehicles is critical due to the assumption of homogeneous traffic streams. An example of such a scenario is at priority intersections. Priority intersections are unsignalized junctions of a major and minor road; where minof road traffic must wait for a suitable gap in the major road in order to merge. In this study, a macroscopic simulation technique is developed for priority intersection. The technique uses a new priority intersection capacity formula derived from a macroscopic approach. The newly-developed capacity formula is analytically tractable and can be modified easily to account for the type of control used at a priority intersection. It is thus ideal for application to traffic simulation software. To demonstrate the applicability of the technique, a macroscopic simulation software package, PRISM (Priority Intersection Simulation Model), is presented. PRISM combines the Cremer-Putensen traffic continuum model and the new capacity formula. |
