Surveys of people’s mobility revealed that the automobile accounts for the large majority of commuting trips in the United States, around 75%. In contrast, public transit only accounted for a long-term average of 5% of commuting trips, which can be perceived as marginal. The modal distribution of commuting in the United States is showing remarkable stability with no significant changes in a period of about 25 years. The most significant change is within the usage of the automobile as carpool, which has experienced a slight decline to the advantage of driving alone. This obviously reflects higher levels of car ownership.
The Covid-19 pandemic represented a paradigm shift in mobility, with a substantial increase in the share of work-from-home (trip substitution) associated with lockdowns and adaptation of segments of the service sector, particularly education and management. Mass transit and carpooling experience a substantial decline, particularly because of epidemiological concerns. It is expected that commuting patterns to resume back to their historical trend with likely a higher share of work-from-home substituted trips.
