How many trucks will take one route through the state versus another? How much freight will they be carrying? How much traffic will just pass through and how much will stop for deliveries or pickups? And why do these questions matter? Forecasts for freight traffic matter because efficient movement of goods supports economic growth. Knowing where the heaviest traffic will be matters to transportation departments that must make decisions about where to build new roads or when to schedule highway maintenance— projects that require long-term planning. Researchers at the University of Alabama in Huntsville have developed a new freight and truck traffic forecasting tool to aid metropolitan planning teams. Their model examines changes in the sizes of populations and key industries, thus showing where local traffic flows may change. It also accounts for pass-through volume—i.e., traffic moving through the region over which the planners have no control. The result is a more accurate picture of freight traffic's future impacts.
