Transportation Demand Management (TDM) is a set of strategies intended to fight congestion by increasing the desire of the traveling public to use modes of transportation other than driving alone, particularly during peak commute periods. The other modes to which TDM strategies try to direct commuters are carpooling/vanpooling, mass transit, walking and biking. If a substantial amount (approximately 20%) of the traveling public are afforded the opportunity to work from home or have work schedules that allow commuting slightly before or after the peak periods, that too would lead to noticeable congestion relief. Since TDM is literally Demand Management, for a particular service (transportation), effective TDM implementation requires optimizing the mix of marketing and transportation planning.
