Akcelik SIDRA Intersection

SIDRA INTERSECTION is a professional traffic engineering software used for: Intersection and roundabout analysis. Signal timing design and optimisation. Road network modelling. Traffic impact assessments and planning. It uses a lane-based, micro-analytical model, meaning it simulates traffic at a detailed level (lane-by-lane behavior, queues, delays, stops, etc.), which is more realistic than traditional aggregate models. In practice, engineers use it to evaluate: Level of Service (LOS). Queue lengths and delays. Capacity and congestion. Effects of design alternatives (e.g., signals vs roundabouts). It also complements standards like the Highway Capacity Manual (HCM) but extends them with more advanced modelling. Version 11 (released March 2026) introduces major new capabilities, especially for network-level traffic assignment and advanced modelling. Key new features SIDRA ASSIGN (bigges
