Route optimization creates the fastest, most efficient plan, reducing out-of-route miles and saving time. When optimizing a delivery route, many variables are taken into consideration, including delivery windows, driver schedules, vehicle load capacity, driver proximity to the warehouse or hub, traffic congestion and accidents, stop locations, parking availability and more. Though this can be done manually, utilizing software to organize the many moving pieces and creating an optimized delivery plan enables routes to be updated in real time to avoid last-minute traffic delays, road closures or weather-related issues.
