Abstract

A new theoretical approach for the determination of capacities at All-Way Stop-Controlled and First-In-First-Out intersections is presented. This approach is based on the Addition-Conflict-Flow method developed from the graph theory. The new procedure considers All-Way Stop-Controlled intersections in such a way that the First-In-First-Out discipline applies. The new procedure can handle most common lane configurations in the real world including multilane approaches. A simple and more practical procedure is recommended. In practice, this simplified procedure can be used for single-lane approaches as well as single-lane approaches with separate left-turn traffic lanes. This procedure is verified and calibrated with measured data from All-Way Stop-Controlled intersections in the USA. For the calculation of capacity at All-Way Stop-Controlled intersections, general parameters, which are determined by calibration, are proposed.
