Several factors can impact the last mile of delivery, including traffic, construction, and weather. Using real-time data from a variety of sources—from GPS data to weather forecasts—routes can be optimized, which can significantly impact fuel, personnel, and other overhead costs. Beyond that, by using GPU-powered smart solutions to optimize routes, carriers can provide more accurate delivery windows, improving the level of service provided to customers. This instills a higher degree of trust, which matters when customers have an array of options for sending and receiving important parcels.
