Unique Lane-Based Analysis of Intersections and Networks
SIDRA INTERSECTION is the only software that employs a powerful and unique lane-based model for intersections and networks.
Realistic traffic analysis of closely spaced intersections requires modelling of driver lane use behaviour. This is lacking in software that use traffic modelling based on lane groups.
SIDRA INTERSECTION is a unique lane-based model that can identify backward spread of congestion, midblock lane changes and unequal approach lane use at closely-spaced intersections.
Capacity and performance results presented in detailed output reports and graphical displays provided by SIDRA INTERSECTION help you in assessing the accuracy of your intersection and network models.
Lane use of traffic is a fundamental factor affecting the model estimates of capacity and level of service, delay, queue length, stop rate, fuel consumption and emissions, travel time and network efficiency as well as signal timing results.
Diverse Movement Classes
Movement Classes can be allocated to different lanes, lane segments and signal phases, providing a unique method for modelling of Bus Priority Lanes, Bicycle Lanes, and so on.
Lane Movements are used to model the blockage of upstream lanes depending on lane choices of movements from approach lanes to exit lanes.
Signal Platoon Movements
SIDRA INTERSECTION uses lane-based second-by-second arrival and departure flow patterns to accurately analyse coordinated signal systems and Common Control Groups.
Powerful Signal Timing Analysis
Signal timing analysis methods in SIDRA INTERSECTION cover an extensive area of application and is based on strong research foundations.
SIDRA INTERSECTION includes extensive treatment of signalised and unsignalised (zebra) pedestrian crossings at intersections and midblock locations.
Routes can be defined in a very flexible way for travel performance results and signal offset calculations.
Based on 40+ years of leading research
SIDRA INTERSECTION has been a valuable technology transfer tool based on 40+ years of leading research carried out in Australia.
