Kinds of transportation, Traffic laws in the USA. Kinds of transportation: Road transportation, Air transportation, Rail transportation, Water transportation. The work of the railroad pioneers in America became the basis for a great surge of railroad building halfway through the nineteenth century that linked the nation together as never before. Railroads eventually became the nation’s number one transportation system, and remained so until the construction of the interstate highway system halfway th...
