sidra intersection is a micro-analytical traffic evaluation tool that employs lane-by-lane and vehicle drive cycle models. it can be used to compare alternative treatments of individual intersections and networks of intersections involving signalised intersections (fixed-time/pretimed and actuated), roundabouts (unsignalised), roundabouts with metering signals, fully signalised roundabouts, two-way stop and give-way (yield) sign control, all-way (4-way and 3-way) stop sign control, merging, single-point urban interchanges, traditional diamond and diverging diamond interchanges, basic freeway segments, signalised and unsignalised midblock crossings for pedestrians, merging analysis and network modelling of these intersection and interchange types.
