When it comes to urban mobility and street design, you might assume that traffic engineering decisions are driven by rigorous scientific research. However, the reality is far more complex and surprising. Despite the critical importance of transportation infrastructure, many traffic engineering choices are still based more on traditional practices and intuition rather than solid, evidence-based research. This disconnect between scientific knowledge and practical implementation can have significant consequences for urban safety, efficiency, and livability. Researchers have long observed that many traffic engineering strategies are rooted in historical precedents and conventional wisdom, rather than comprehensive data analysis. While engineers are increasingly recognizing the value of empirical studies, the translation of research findings into actual policy and design remains slow and inconsistent. Key challenges include: • Limited funding for comprehensive research • Resistance to changing established practices • Gaps between academic research and practical application • Complexity of implementing new, data-driven approaches The good news is that a growing movement of transportation professionals is pushing for more evidence-based decision-making. By embracing data, technology, and interdisciplinary research, cities can develop smarter, safer, and more efficient transportation systems that truly serve community needs.
