  Understanding the Origin-Destination Matrix: Concept, Uses, Benefits, and Applications The Origin-Destination (OD) Matrix is a vital tool in transportation planning, logistics, and urban studies, offering deep insights into movement patterns between locations. By mapping the flow of people, goods, or vehicles from origins to destinations, the OD Matrix enables analysts to optimize routes, enhance infrastructure, and make data-driven decisions. In this article, we explore the concept of the OD Matrix, its uses, benefits, weaknesses, and real-world applications. What is an Origin-Destination Matrix?
