Dr. Kara Kockelman, associate professor of transportation engineering, received the 2007 Harland Bartholomew Award from the American Society of Civil Engineers (ASCE). Kockelman was recognized for her ‘credit-based congestion pricing’ theory, which uses variable toll rates to eliminate recurring traffic congestion while allocating scarce road space equitably. She is considered a leading expert in modeling travel (and land use) conditions under tolled and non-tolled scenarios, and in evaluating the impacts of transportation system policies. The award is given annually to an ASCE member who enhances the role of civil engineers in urban planning and development.
