Traffic Simulation Comes to Autodesk InfraWorks 360

Designing roadways is often a complex and iterative process, requiring careful consideration of geographic limitations, budget constraints, safety standards, and traffic capacity. The new traffic simulation and analysis tools in the latest version of Autodesk InfraWorks 360 help streamline this process by enabling teams to evaluate designs within a single intelligent 3D model. This not only improves accuracy but also reduces the time needed for internal approvals, as all stakeholders can review and validate the final design more efficiently.

Beyond traffic simulation, the update includes several other improvements aimed at enhancing collaboration and design flexibility. One notable addition is the ability to share models in read-only mode, giving users more control over their data. Additionally, new features have been introduced for road, rail, and bridge design, further expanding the tool’s capabilities.

Traffic Simulation

The Traffic Simulation feature, previously available as an Autodesk Labs Preview, has now become a full-fledged part of Roadway Design in InfraWorks 360. This powerful tool allows designers to run detailed traffic simulations directly within the software, helping them make more informed decisions early in the design phase. With this functionality, users can define traffic flow patterns, specify peak hours, set up turn lanes, and even simulate signalized intersections and roundabouts.

This level of detail gives designers greater confidence when passing their work to traffic engineers for deeper analysis. It also minimizes back-and-forth revisions, as potential bottlenecks and capacity issues can be identified and resolved during the initial design stage.

The intuitive interface of the Traffic Simulation module clearly highlights roads that exceed capacity, making it easy to spot areas needing improvement.

In addition to traffic simulation, the update brings several enhancements across different design disciplines:

• Rail Design: Users can now create custom rail styles, offering more flexibility when designing structures like tunnels, viaducts, and station platforms. Rail features can also be grouped together, allowing a single bridge to support multiple tracks instead of building separate ones for each. Transition lengths between rail styles are now customizable.

• Road Design: The latest update improves intersection modeling with support for staggered intersections, right-in/right-out, and left-in/left-out configurations. Roundabouts now accommodate both left- and right-hand drive traffic and include standard road markings and yield lines, making the design more realistic and accurate.

• Bridge Design: Piers and foundations now come with a library of alternative styles, allowing for more realistic models. These components can be customized via the asset card, and changes to one component can be easily applied across similar elements. Model regeneration and volume calculations now occur only when necessary, improving performance and efficiency.

The grouping feature in InfraWorks 360 allows a single bridge to support multiple rail tracks, increasing design efficiency.

Enhanced intersection tools allow for more complex designs, such as staggered intersections, improving flexibility and realism.
