This paper introduces a framework, in the form of a tree diagram, for understanding the relationships between the benefits of a transit service. This benefit tree displays what might happen as the result of a transit service. The five main branches of transit consequences are: (1) transit provides an alternative transport mode; (2) transit affects land use and economic activity; (3) transit trips are made because fewer car trips are made; (4) transit trips are made because passengers prefer to travel by transit; and (5) a transit service is provided. Each main branch has its own subtree, whose branches correspond to possible benefits and reduction of harmful effects. For example, transit reduces environmental effects, such as air and noise pollution and energy use, and also reduces the impact of unusual circumstances such as accidents or severe weather. `Neutral' effects include various types of user effects and facility needs. People-oriented benefits include: (1) improvements in well-being and lifestyle; (2) independent living; (3) interaction between people; (4) community support; (5) employment; and (6) travel for pleasure. Other benefits include: (1) long-term option; (2) efficiency of public services; and (3) land preservation.
