the lane-based network model provides information about departure and arrival patterns, queue lengths, lane blockage probabilities, backward spread of queues, and so on at a lane level. the model allows for the effect of upstream lane use patterns on downstream signal platoon patterns, in turn affecting the estimates of network performance measures (travel time, delay, back of queue, stop rate). this is important especially in evaluating closely spaced (paired) intersections and interchanges with high demand flows where vehicles have limited opportunities for lane changing between intersections. such facilities include staggered t intersections, freeway signalised diamond interchanges, freeway roundabout interchanges, fully signalised roundabouts (including signalised circulating roads), large signalised intersections with wide median storage areas, staged crossings at sign-controlled intersections, intersections with nearby pedestrian crossings, and alternative intersection and interchange configurations such as diverging diamond interchanges (signalised), continuous flow intersections, restricted cross-street u-turns, and so on. the modelling of arrival patterns at downstream approach lanes takes into account implied midblock lane changes. different movement classes (light and heavy vehicles, buses, large trucks, bicycles, and so on) are treated individually in modelling platoon arrival and departure patterns.
