The adverse effects of traffic on the quality of life have become undeniable, with congestion, noise, and pollution significantly impacting urban environments. Large construction projects risk exacerbating existing traffic problems or creating new ones without proper traffic planning and management. Notably, most existing studies predominantly concentrate on the post-construction phase of buildings, neglecting the broader temporal spectrum of project development. The importance of traffic studies is further underscored as they provide a proactive framework for planners, policymakers, and developers by delv-ing into the nuances of traffic impact during the entire project lifecycle. This forward-looking perspective empowers stakeholders to make informed decisions, prioritizing mitigating traffic-related problems and enhancing the overall quality of life in urban environments. Previous research has focused on investigating a building's impacts on surrounding traffic after completion. However, traffic conditions beforehand and during construction are just as vital. Especially major healthcare projects that result in daily trips to and from the project, as in the case study at the Sheikh Zayed Institute for Oncology, by monitoring traffic conditions before, during, and after implementing the project and determining the extent of the project's impact on traffic axes around the project. By assessing traffic across pre-planning, execution, and post-occupancy, this research aims to determine the quality-of-life consequences better and provide recommendations. A holistic traffic evaluation approach supports informed decision-making to design new developments appropriately and upgrade existing networks for maximum mobility and livability. They are addressing traffic proactively to manage urban growth sustainably.
