SIDRA Intersection (v11.0.2.66)
Looking for software that can calculate intersection capacity or a road’s level of service? SIDRA Intersection Full (v11.0.2.66) is worth a try. Its main job is to analyze capacity, LOS, delays, and queue lengths at signalized intersections. It integrates with Aimsun Next, and its methodology aligns with the HCM.
Released on March 31, 2026, this version is really just a bug-fix update. There are no new features, only fixes for cloud licensing, OD Presets errors, and the auto-updater that had been broken since v11.0.1.
The big feature came with the initial v11.0 release: SIDRA Assign. This multimodal traffic assignment module offers five methods, including Stochastic User Equilibrium, and shows the effects of queue spillback.
If your work also involves bridge design, CSI Bridge Advanced can complement it. Need to analyze building structures? CSI SAP2000 Ultimate is a better fit.
SIDRA focuses specifically on traffic, just like Synchro plus SimTraffic.
