	The lane-by-lane capacity and performance analysis method used by Sidra Intersection includes identifying any de facto exclusive lanes, unequal lane utilisation, lane change, modelling of short lanes (turn bays, lanes with parking upstream, and loss of a lane at the exit side) and lane blockage in shared lanes including lanes containing opposed (permitted) turns, slip (bypass) lane movements and turns on red. Intersections and networks can be modelled in detail using this method and signal timings can be determined accordingly with advantages over approach-based and lane group-based methods.
