From Business Case to Value Case : brede welvaart in decision-making for traffic management

The TrafficQuest challenge of 2025 builds on the challenge of 2022 about Traffic Management and Human Well-Being (Brede Welvaart). However, with this year’s challenge, the team dove deeper into the application of brede welvaart in decision making for Traffic Management projects at Rijkswaterstaat by investigating how we can move from business cases to value cases. This added a new dimension to the discussions about brede welvaart and allowed the team to expand their knowledge on business cases and value cases. The interviews and the workshop with Rijkswaterstaat and TNO-experts on traffic management, brede welvaart, and economics, resulted in interesting discussions. Besides the valuable insights they provided, the sessions were also valuable because of how they (re-)connected experts across different domains – which is also part of one of the recommendations of this report.
