Abstract

This technical note has been prepared in response to a question raised by R.L. Pretty (regarding the lane flow estimation method used in the SIDRA program for signalised intersection analysis The question is: 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? Related to this is the question of lane underutilisation, that is, unequal lane utilisation. Whether the definition of lane underutilisation based on relative degrees of saturation (as in SIDRA) should be used irrespective of the lane flow estimation principle, or lane underutilisation should be defined according to the lane flow estimation principle used, is another issue to resolve. This note also discusses a recent paper by C.S. Fisk, which raises the issue of the relationship between lane choice and route choice principles in a more general context.
