Conversion of rural and semi rural major/minor T junctions to offside priority

Trrl Lr 883 Flow and delay data obtained at five major/minor T-junctions before and after conversion to offside-priority have been used to provide general criteria for conversion of major/minor systems to mini-roundabouts. Two approaches have been adopted. The first is intended to provide an approximate method of estimating the 24-hour delays before and after conversion and the second criter…

Traffic queues and delays at road junctions

Methods are described for the prediction of queue lengths and vehicular delays at road junctions subject to time-varying traffic demand and capacity. The properties of individual traffic streams are developed firstly in terms of the probability distribution of queue lengths, and scondly by approximation formulae which allow queues and delays to be predicted directly. Two approaches are used: (i…
