Initiative details
Roadscor tackles critical road safety challenges by shifting from reactive to proactive design evaluation, especially for vulnerable road users (VRUs) at urban intersections. Traditional safety assessments rely heavily on historical crash data or near-miss observations, which are often incomplete or outdated. This limits the ability to anticipate and prevent future incidents. Roadscor introduces a groundbreaking methodology that uses advanced traffic simulation and automotive-grade scenario analysis (aligned with ISO 21448 – Safety of the Intended Functionality) to identify both known and unknown high-risk traffic conflicts - before they occur.
By simulating all physically possible interactions between road users, including pedestrians and cyclists, Roadscor enables traffic engineers to quantify safety risks and evaluate the impact of design changes or behavioral measures prior to implementation. This data-driven approach supports more effective, evidence-based decision-making and helps prioritize interventions where they will have the greatest impact. Ultimately, Roadscor empowers cities and road authorities to design safer, more inclusive infrastructure, accelerating progress toward Vision Zero goals.

Please describe the project activities you carried/are carrying out and the time period over which these were implemented.
The ROADSCOR project, funded by EIT Urban Mobility, started January 2025 and aims to improve road safety for vulnerable road users (VRUs) by advancing its conflict analysis methodology from TRL7 to TRL9. The project is led by Roadscor, in collaboration with Haskoning, Siemens Industry Software Netherlands, and Aimsun. Notably, the Province of Noord-Brabant (Netherlands) placed the first commercial order for Roadscor, demonstrating early market traction and validating the methodology’s practical value.
In Stage 1, the consortium conducts safety assessments at two urban intersections in Hasselt (Belgium) and Rome (Italy), focusing on identifying and mitigating high-risk traffic conflicts. Each site undergoes two iterations: one for the current layout and one incorporating safety improvements.
Stage 2 focuses on defining the safety score and preparing the methodology for transformation into a SaaS product. This includes stakeholder workshops, KPI development, and product-market fit analysis, with support from FIA Mobility.

In terms of implementation, what worked well and what challenges did you need to overcome?
The transition of Roadscor from a tool originally developed for autonomous vehicle safety to one tailored for traffic engineers and road authorities is both challenging and rewarding. A key success was the ability to adapt Siemens’ patented Critical Scenario Creation methodology - originally used to identify unknown-unsafe scenarios for vehicles - to the broader context of urban intersections involving vulnerable road users. This shift enabled traffic engineers to proactively assess safety risks without relying on historical crash data.
What worked particularly well was the collaboration between Roadscor, Royal HaskoningDHV, Siemens, and Aimsun. Their combined expertise ensured that the methodology was not only technically sound but also practically applicable in real-world traffic engineering workflows.
However, challenges include incorporating traffic engineering requirements into the current software as well as presenting simulation outputs into actionable insights for non-technical stakeholders such as city planners and policymakers. Ensuring that results were presented in a clear, decision-supportive format required iterative feedback and refinement. Additionally, training traffic engineers to use a tool originally designed for automotive engineers demanded tailored onboarding and workflow adjustments.
Overall, the project is demonstrating that with the right partnerships and user-centered design, advanced automotive safety technology can be successfully repurposed for public road safety planning.

Evaluation
Please summarise how you have evaluated the initiative’s impact (e.g. social media reach, survey, feedback forms, statistics).
The impact of the Roadscor initiative is measured per intersection assessed, using a data-driven methodology that quantifies the number and severity of potential traffic conflicts. For example, in a previous assessment the methodology led to the mitigation of critical conflict scenarios. These improvements translated into an estimated socio-economic benefit of $5 to $10 million, based on the reduction in serious injuries and fatalities. This case illustrates how Roadscor enables road authorities to make informed, cost-effective decisions by evaluating the safety impact of design modifications before implementation.
In addition to technical assessments, feedback is collected during the ROADSOCR project through structured workshops and stakeholder sessions, including those facilitated by FIA Mobility. These sessions involve city officials, road safety experts, and international organizations such as iRAP and UNITAR. Participants provide input on the tool’s usability, the clarity of its outputs, and its value in supporting policy and planning decisions.
The results of each intersection analysis are documented in demonstration reports and discussed with local stakeholders, ensuring that the findings are validated and actionable. This approach ensures that Roadscor’s impact is both measurable and meaningful for improving road safety.

What has been the effect of the activities?
The ROADSCOR initiative has demonstrated measurable impact at both local and international levels. Each intersection assessment quantifies the number and severity of potential conflicts, enabling road authorities to make informed design decisions. For example, a prior analysis showed that redesigning an intersection based on ROADSCOR’s methodology could prevent serious injuries or fatalities, translating into a socio-economic benefit of $5-10 million.
While the EIT Urban Mobility project is ongoing, early dissemination activities have already reached hundreds of stakeholders through conferences, workshops, and digital channels. The future inclusion of Roadscor in FIA Mobility’s global training program and its promotion through a network of 243 automobile clubs ensures international visibility and uptake.
Roadscor is particularly effective because it enables traffic engineers to assess safety improvements virtually, reducing the need for costly and time-consuming physical trials. It complements existing tools by offering a forward-looking perspective, helping cities meet Vision Zero goals and improve safety for vulnerable road users in a scalable, data-driven, and cost-efficient manner.

Please briefly explain why your initiative is a good example of improving road safety.
ROADSCOR improves road safety by identifying high-risk traffic conflicts before crashes happen, using simulation instead of historical crash data. This proactive, data-driven approach helps cities design safer intersections - especially for vulnerable road users. The method is easy to adopt: it integrates with existing traffic modeling tools and is offered as a service, with a SaaS version coming soon. With minimal training, traffic engineering companies can easily apply it to intersections in other cities, making it a scalable and effective solution.
How have you shared information about your project and its results?
Roadscor has actively shared its approach and results through a range of communication channels and events. Information has been published on the website and LinkedIn page, targeting traffic engineers and road safety professionals. The project will present at major international conferences, including ITS Europe (Seville), International Transport Forum (Leipzig), ITS World Congres (Atlanta), Road Safety on 5 Continents (Leeds), Smart City Expo World Congress (Barcelona), Urban Planning & Architectural Design for Sustainable Development (Florence), Nationaal Verkeerskunde Congres (Roermond) and Polis Annual Conference (Utrecht).
Additionally, Roadscor will be featured in FIA Mobility’s global outreach, including newsletters and social media, reaching 243 automobile clubs across 147 countries.
