On the Estimation of Lane Flows for Intersection Analysis

Abstract

This article responds to the question "Which principle should be used as a basis for estimating lane flows at the approaches to an intersection, and how does this principle relate to the lane choice decisions of individual drivers? ". Equal degree of saturation, equal average delay, minimum travel time, equal queue length principles are discussed. Relationship between lane choice and route choice principles, interaction with signal timings, and relation to the Level of Service criteria are also considered.
