Abstract

This presentation discusses main features of the network signal timing methodology which has been under development for the SIDRA INTERSECTION software (current Version 6.1 and the forthcoming Version 7). Direct elements of the network signal timing method includes lane-based second-by-second-platoon model using signal offsets, network cycle time and intersection phase time calculations, signal offset calculations, and common control groups (for signalised intersections controlled by a single signal controller). The general aspects of the network model that affects network signal timing include lane blockage (upstream saturation flow rates are reduced) and capacity constraint (downstream arrival flow rates are reduced) as well as the lane movements at the upstream intersection and the midblock lane changes affecting downstream platoon patterns.
