This paper describes ways to improve LEED (Leadership in Energy and Environmental Design) transportation and parking credits. Typical LEED programs reduce building energy consumption 20-60%. Cost effective mobility and parking management programs often provide similar motor vehicle trip and parking generation reductions, resulting in large economic, social and environmental benefits. However, the current LEED rating system overlooks some of the most effective mobility and parking management strategies. It encourages practitioners to choose strategies based on their ease of implementation rather than effectiveness. As a result, the current LEED rating system is unlikely to implement mobility and parking management as much as optimal.
