摘要：	For well over 15 years, the ASCE Journal of Transportation Engineering, Part A: Systems and its predecessor journals have been publishing articles on public and urban transportation (Sinha 2021). Public transportation papers have addressed planning, design, construction, and operation for multiple transit modes, including buses, light rail, and heavy rail. The focus of this work has largely been on urban public transportation in Canada and the United States, and we will continue that focus in this editorial. We will also use the terms public transportation and transit interchangeably. In North America, the first national crisis for public transportation occurred post-World War n, when the vast majority of privately run North American public transportation systems essentially went bankrupt and were taken over by publicly operated and local transportation authorities. These systems were generally designed for commuter travel from the external suburbs to the central business district (CBD). Such legacy commuter routes were often light or heavy rail. They still exist and still serve these commuter movements. For the past 60 years, public transportation systems have been operated as a social service. With few exceptions, public agencies did not have the funds to develop new subway lines and instead relied on extending bus routes to address new passenger movements (e.g., suburb to suburb). In this way, public transportation in North America is now designed and operated to provide mobility for citizens who, for a variety of reasons, do not have access to automobiles. However, because of cost considerations, the service times of the new services have been relatively high. The result is that, while it is relatively easy to travel from a suburb to downtown, traveling from suburb to suburb, or even within a given area, often takes a substantial amount of time, particularly when compared with private vehicles.
