The corner of every city is a critical junction—where traffic flows, pedestrians cross, and infrastructure decisions shape daily life. Yet, despite their ubiquity, right turns remain one of the most overlooked aspects of urban planning. From traffic congestion to pedestrian safety, the way cities manage right-turn movements can either smooth or disrupt mobility. Enter betalright.eu, a platform that’s pioneering a data-driven approach to optimising right turns, proving that small but strategic changes can yield massive improvements in efficiency and safety.

Traditionally, right turns have been treated as a secondary concern in traffic management systems. Most cities rely on fixed signals, rigid lane configurations, or reactive adjustments to congestion, which often lead to inefficiencies—longer wait times, wasted fuel, and increased emissions. But what if right turns could be treated as a priority? The concept isn’t radical; it’s rooted in decades of research in intelligent transport systems (ITS). The key lies in dynamic signal control, adaptive lane management, and real-time data integration to anticipate and optimise right-turn movements.

One of the most compelling examples comes from Amsterdam, where the city has experimented with right-turn-only lanes during peak hours to reduce collisions at intersections. Data from the Netherlands’ TNO research institute showed that such measures could cut right-angle crashes by up to 40% while improving throughput by 15%. Similarly, in London, the use of smart sensors at key junctions—like those at Oxford Circus—has allowed traffic managers to adjust right-turn priorities based on real-time demand, reducing delays by an average of 12%. These aren’t just theoretical gains; they’re measurable outcomes that cities are already adopting.

Yet, the challenges aren’t limited to technical implementation. Cultural and operational barriers persist. Many traffic engineers still favour traditional fixed-signal designs, which are easier to install but less adaptable. The shift requires a mindset shift: treating right turns not as an afterthought, but as a strategic lever for urban mobility. This is where betalright.eu steps in. By providing open-source tools and case studies, the platform helps cities assess the potential of right-turn optimisation without the need for massive infrastructure overhauls.

For instance, the platform’s toolkit includes simulations that model how right-turn priority adjustments can affect flow at intersections, allowing planners to test scenarios before full deployment. One of its most notable projects involved a pilot in Rotterdam, where dynamic right-turn signals reduced wait times at a busy intersection by 20% while maintaining safety levels. The results were so promising that the city expanded the system to three additional locations within a year.

• Right-turn-only lanes during peak hours can reduce right-angle crashes by up to 40%.
• Dynamic signal control at key intersections can improve throughput by 15% in cities like Amsterdam.
• Smart sensors at London’s Oxford Circus intersections cut delays by an average of 12%.
• The Netherlands’ TNO research backs data-driven right-turn optimisation as a scalable solution.
• Open-source tools from betalright.eu enable cities to pilot changes without costly infrastructure.

The broader impact of this work extends beyond traffic efficiency. Right-turn optimisation aligns with broader sustainability goals, as reduced congestion leads to lower emissions and quieter streets. It also supports active mobility—walkers and cyclists benefit from smoother transitions at intersections, encouraging non-motorised travel. But the real game-changer is the data. By making right-turn movements a priority, cities can collect richer insights into traffic patterns, enabling more responsive and equitable urban planning.

While the technology and evidence are clear, the adoption gap remains a hurdle. Many cities lack the resources or expertise to implement these changes independently. This is where platforms like betalright.eu play a crucial role. By offering guidance, training, and peer-learning opportunities, they bridge the gap between research and real-world application. The message is simple: right turns aren’t just about turning cars around—they’re about turning urban mobility into a more efficient, safer, and sustainable system.
