Optimization of Traffic Arrangements in Stockholm Using Autopath Software
Challenge: Traffic Safety on Narrow Roads in Stockholm
Stockholm, one of Europe’s fastest-growing capitals, faces ongoing challenges in traffic planning and management—especially in projects that involve redesigning traffic systems on narrow urban roads near schools, bus routes, and densely populated areas. These environments present complex conditions due to limited space and high traffic volumes, requiring solutions that ensure the safe and smooth movement of buses, cars, cyclists, and pedestrians, all while complying with the strict safety and design standards of Trafikverket. Traffic engineer Semu Kassahun has been involved in several such projects, using specialized planning software to simulate traffic behavior and identify optimal placements for signs, lane adjustments, and safety barriers. The traffic plans were submitted to both municipal authorities (e.g., Stockholm Stad) and Trafikverket for review, and refined until they met all regulatory requirements.
In several semi-complex projects, Semu conducted detailed maneuverability analyses using Autopath, which were reviewed by key stakeholders including local governments, traffic experts, and public transport operators. Among these projects are the Ältastråk project, Förbifart Stockholm at Nockeby, Lilla Lidingö Bridge, and New Skurubron. These efforts highlight the importance of digital tools, collaboration, and precision in traffic planning. With the support of Autopath, Semu and his team could reduce the need for manual calculations, minimize errors, and deliver well-coordinated traffic solutions that ensure safety and efficiency throughout every stage of the project.
Solution: Use of Autopath Software
In search of a reliable solution for creating swept path analysis and optimizing traffic arrangements, Semu chose Autopath. Autopath enabled quick and efficient traffic arrangement planning, which was essential for obtaining approval from local authorities and bus operators.
With Autopath, Semu simulated the driving paths of Swedish buses, which have specific dimensions, through construction zones. The software provided detailed analyses, allowing the team to adjust road widths and traffic sign locations accurately.
Process and Results
Creating traffic management plans (Trafikanordningar) for projects involving both Trafikverket and municipal road authorities requires detailed planning, strong coordination, and compliance with multiple regulations. These plans are typically needed for construction or maintenance work and must ensure the safety of all road users—including drivers, pedestrians, and cyclists—while maintaining access to public transport. Tools like Autopath and traffic simulation software are used to analyze vehicle paths, sign placements, visibility, and barrier positions.
A key challenge is balancing Trafikverket’s requirements for national road safety and traffic flow with municipal priorities, such as accessibility, noise control, and protection for vulnerable road users. Traffic engineer Semu Kassahun used planning software to simulate traffic movements and determine optimal locations for signage and lane adjustments. Plans were submitted to both Trafikverket and the local municipality (e.g., Stockholm Stad) for feedback and revised accordingly until all safety and design standards were met. These projects highlight the importance of collaboration and digital tools in delivering safe, efficient, and sustainable traffic solutions.
The results were very positive. Efficient planning and implementation allowed for timely project completion with minimal traffic disruptions. Additionally, Autopath significantly reduced the need for manual calculations and reviews, saving time and reducing the risk of errors.
Benefits of Using Autopath
Semu highlighted the following key advantages of using Autopath in the project:
- Accuracy and Reliability: The swept path analysis were precise and compliant with Swedish standard, ensuring reliable results for the project.
- User-Friendly Interface: The intuitive and easy-to-use interface allowed for rapid team training.
- Time Savings: Automated simulations and integration with other CAD tools significantly shortened the time required for vehicle maneuverability analyses.
- Vehicle Libraries: The extensive vehicle library, including those that meet Swedish standards, made it quick and easy to perform analyses, further enhancing the reliability of the simulations.
