TSM is a short-range element of a regional transportation planning process that addresses ways to improve overall transportation system performance through various low-capital or no-capital management actions. Such actions can be intramodal (e.g., improved transit scheduling techniques, bikeway or pedestrian facilities, express bus operations), intermodal (e.g., bus priorities on streets, parking restrictions, relocation of bus stops that impede traffic flow), or extramodal (e.g., staggered work hours, pricing strategies to discourage long-term parking, employer incentives for ride sharing). The heart of TSM is a concept in which the urban transportation system is a single entity and federal funds are transportation resources. The goal of TSM is to increae the systemwide efficiency of people and goods movement withoug significant new infrastructure investment, rather than to simply accommodate increasing vehicle travel. Ideally, TSM is regional in scope, goal-oriented, and intermodal and has its principal leadership and coordination provided through the MPO. In practice, such strategic approaches are rare; TSM is most commonly of a tactical nature involving site-specific actions that have marginal effects on systemwide performance. The recent corridor-study approaches, however, are a potential way to reconcile the practical advantages of tactical TSM with a basic thrust toward strategic planning, particularly to achieve air quality and energy-conservation goals.
