Last mile is the final stage of the logistics chain, covering the movement of goods from a distribution hub to the end recipient's address. It is widely regarded as the most complex and costly segment of the supply chain, as it involves high delivery density, time-sensitive demands, and direct interaction with the consumer or end user. In urban logistics, last mile operations face challenges such as traffic congestion, failed delivery attempts, and sustainability pressures. Smart locker networks and PUDO (Pick Up Drop Off) points have emerged as effective solutions to optimise last mile delivery by decoupling the moment of dispatch from recipient availability. Columat's smart locker infrastructure supports last mile operators in reducing failed deliveries and operational costs whilst improving the recipient experience. Related concepts include PUDO points and out-of-home delivery.
