sidra intersection includes fixed-time / pretimed (equisat) and actuated signal timing analysis methods for intersections with any geometry allowing for simple as well as complex phasing arrangements. in addition to the traditional methods for signalised intersection cycle time (practical, optimum and user-given) and green split methods, it includes advanced signal timing methods such as a unique critical movement analysis method, variable phasing analysis, green split priority for coordinated or user-specified movements, and allows the use of two green periods for modeling slip / bypass lanes, permitted-protected turns, and turn on red. network signal timing methods are available to determine cycle time (practical, optimum and user-given), green times and signal offsets for coordination of signalised intersections controlled by separate signal controllers as well as common control group timings for intersections running under a single signal controller. the lane-based network model includes detailed movements of vehicle platoons with lane changes between signalised intersections for assessing the efficiency of signal coordination and optimising signal timings for signalised intersection networks.
