For example, a new highway or railway line may open up previously inaccessible regions, making it possible for businesses to transport goods and people more easily and efficiently.Job creation: Developments in transportation can also create new jobs in industries such as shipping, logistics, and transportation services. This can have a multiplier effect on the economy by creating additional demand for goods and services in other sectors.
