This brief, The Role of Commuting in Overall Travel, sets work commuting in context with other aspects of travel, specifically other purposes for travel. America’s transportation infrastructure and services address the needs of individuals for all their travel purposes and also serve the travel needs of commerce and government. Commuters’ vehicles share the roadways with vehicles carrying persons who are traveling for school, shopping, personal business, social and recreational activities, and other purposes, and they also share the road with vehicles transporting freight and providing various services, from goods delivery to emergency response to service workers visiting customers. Visitors and tourists from other communities and countries also share the transportation facilities. Similarly, transit services transport work commuters but also travelers pursuing other activities.
