SIDRA INTERSECTION is the most widely-used software tool in the USA for roundabout capacity and performance analysis According to the US Transportation Research Board document "Roundabout Practices", SIDRA INTERSECTION is the most widely-used software tool in the USA for roundabout capacity and performance analysis, followed by Synchro and HCS, based on a survey of state transportation departments (based on 28 of the 37 state agencies responding to the survey question). The report also states "To analyse roundabout performance, about three-quarters of the reporting states use some form of the...

Powerful Network Signal Timing Analysis Network timing for signal coordination involves Network Cycle Time and Site Phase Time calculations as well as Signal Offsets calculated for Routes defined by users. Network Cycle Time, Site Phase Times and Signal Offsets can be specified by the user. Signal timings for Common Control Groups (CCGs), i.e. several signalised intersections operating under one signal controller, are calculated using a unique method that treats each CCG as a single entity.    Graphical Interactive Offsets function Interactive Offsets function allows the user to modify Offsets...

Improve the quality of your model calibration We provide Excel Applications as useful tools for field surveys of Back of Queue and Queue at Start of Green (or Start of Gap), Saturation Flow and Lost Time. These help with calibration of SIDRA models for signalised intersections, interchanges, roundabouts, sign-controlled intersections and pedestrian crossings. The survey methods in our Excel applications are consistent with the fundamentals of the traffic models used by SIDRA. This will help you to employ a sound model calibration methodology in your work.
