What SIDRA SOLUTIONS does
SIDRA SOLUTIONS, trading name of Akcelik & Associates Pty Ltd, is a privately held Australian software company founded in 1999 and headquartered in Melbourne that develops SIDRA INTERSECTION, lane-based micro-analytical traffic modelling software used to analyse, design, and evaluate signalised and unsignalised intersections, roundabouts, sign-controlled intersections, interchanges, signalised mid-block crossings, signal coordination, and road networks. The product performs deterministic analytical computations locally on a Windows desktop client, drawing on proprietary research grounded in Highway Capacity Manual and AUSTROADS guidelines, and supports multimodal analysis by movement class (light vehicles, heavy vehicles, buses, bicycles, large trucks, light rail), probabilistic queue models, gap acceptance models, signal timing optimisation, and environmental assessment including fuel consumption and emissions. The portfolio has expanded to include SIDRA ASSIGN (a traffic assignment module launched with Version 11 in March 2026), SIDRA MAPS, SIDRA API, SIDRA DOCS, SIDRA UTILITIES (VOLUMES Utility, SIP9 Converter, and field-survey Excel applications), and the SIDRA ACADEMIC PACKAGE for universities.
The company generates revenue through a hybrid model that, as of March 2025, is in transition: new customers subscribe annually via Personal (single named user) or Team (concurrent seats with admin portal) tiers covering software, support, and updates for 12 months, while existing perpetual license holders (1PC, SINGLE, FLOATING) maintain access and renew COVER maintenance subscriptions. A separate Educational licensing channel serves recognised universities, TAFEs, and research institutions at reduced pricing with watermarked output and non-commercial-use conditions. Go-to-market is sales-led, combining direct e-commerce via sidraintersection.com for Australia and global new customers with a non-exclusive network of 30+ authorised resellers and dedicated country representatives across the Americas, Europe, the Middle East, South Asia, Africa, and Southeast Asia, supplemented by Platinum Patron presence at the TRB Roundabouts Conference, structured paid and free webinar training (Introduction to SIDRA, SIDRA Model Fundamentals, Project Managers & Reviewers, SIDRA ASSIGN workshops), and an academic pipeline built on the free SIDRA ACADEMIC PACKAGE. The company holds ISO 9001:2015 certification (Certificate #QEC27492), serves transport professionals in over 80 countries, and has no disclosed external funding rounds, institutional investors, or parent company.

SIDRA SOLUTIONS competitors and assessment
Company assessmentDirect peers
- TSS - Aimsun (Transport Simulation Systems): Aimsun develops traffic simulation software (Aimsun Next) for mesoscopic, microscopic, and hybrid traffic modelling. Competes with SIDRA in the intersection and network modelling space, with broader multimodal capabilities and a stronger cloud-deployment story.
- PTV Group: PTV Group (now part of Umovity) develops PTV VISSIM, VISTRO, and VISUM — multimodal traffic simulation and analysis software widely used by transport engineers and planners. Directly competes with SIDRA INTERSECTION in intersection and network modelling, though PTV's portfolio is broader (microsimulation, macroscopic planning, real-time traffic management).
- INRO Software (Emme): INRO develops Emme, a transportation planning software platform used for multimodal demand modelling and traffic assignment. Competes with SIDRA ASSIGN for strategic transport planning and O-D matrix workflows, with a stronger base in North American agencies.
- Caliper Corporation (TransCAD): Caliper's TransCAD is a transportation planning GIS software used for travel demand modelling and network analysis. It overlaps with SIDRA ASSIGN's strategic planning and O-D matrix capabilities, though TransCAD is more macro-level and less lane-accurate.
- Transoft Solutions: Transoft Solutions develops traffic engineering software including TORUS, AutoTURN, and NEXUS. TORUS is a roundabout and intersection design tool that directly overlaps SIDRA's intersection analysis capabilities, and the two companies have an integration partnership announced in 2025.
- McTrans Center (HCS): McTrans at the University of Florida distributes Highway Capacity Software (HCS), which is the US HCM-aligned reference tool for signalised intersection, roundabout, and freeway analysis. HCS is a primary standard-aligned alternative to SIDRA INTERSECTION for North American practitioners.
Broad incumbents
- Iteris: Iteris provides the ClearMobility Platform combining traffic engineering software, sensor data, and managed services for transportation agencies. Operates as a broad incumbent across intersection analytics, traffic management, and smart mobility — overlapping with SIDRA at the intersection analysis layer but with a much broader service portfolio.
- Trafficware (SynchroGreen): Trafficware, now part of Cubic Transportation Systems, developed Synchro and SimTraffic for signal coordination and intersection analysis. Competes with SIDRA for signalised intersection timing work, with deeper integration into real-time adaptive signal control systems.
- Autodesk (InfraWorks / Civil 3D): Autodesk's InfraWorks and Civil 3D provide roadway design and infrastructure modelling capabilities that touch on intersection design workflows. While not a direct competitor on micro-analytical traffic modelling, Autodesk's broad platform presence makes it a relevant adjacent peer in the transportation design ecosystem.
- Bentley Systems (OpenRoads / CUBE): Bentley offers OpenRoads for roadway design and CUBE (formerly Citilabs) for transportation planning and demand modelling. CUBE Voyager competes directly with SIDRA ASSIGN for traffic assignment work, and Bentley's deep infrastructure footprint makes it a broad incumbent rather than a niche specialist.
