This unique text focuses on the key engineering skills required to practice traffic engineering in a modern setting. It includes material on the latest standards and criteria of the Manual on Uniform Traffic Control Devices (2003 Edition and forthcoming 2010 Edition), the Policy on Geometric Design of Highways and Streets (2004 Edition), the Highway Capacity Manual (2000 Edition and forthcoming 2010 Edition), and other critical references. It also presents both fundamental theory and a broad range of applications to modern problems.
Dr. Roger P. Roess is Department Head in the Department of Civil Engineering at Polytechnic Institute of NYU. Elena S. Prassas is an Associate Professor in the Department of Civil Engineering at Polytechnic Institute of NYU. She earned her Doctor of Philosophy and Master of Science from Polytechnic University, and her Bachelor of Arts from the State University of New York, Oneonta. She is a Member of TRB's Highway Capacity and Quality of Service Committee (HCQSC), the Chair of the HCQSC Signalized Intersection Subcommittee, and a Member of both the ITE and WTS. William R. McShane is the Vice President of Operations and Dean of Engineering at Polytechnic University. He earned his B.S.E.E from Manhattan College and his M.S. and Ph.D. In Systems Engineering from Polytechnic University.
