"Microscopic Simulation and Safety Analysis of Roundabouts"

Speaker: 

Dr. Nezamuddin, Assistant Professor of Civil Engineering, Valparaiso University

Abstract:  Although circular junctions are usually associated with the British, their presence in the United States dates back to at least 1905 when Columbus Circle was built near Central Park in New York. Those early twentieth century circular junctions, called traffic circles, were designed for high-speed entries into the circular area and gave priority to the entering vehicles over the circulating vehicles. That was a recipe for disaster. High crash experience and choked traffic circles meant that circular junctions will never gain ground in the United States again. In the 1960s, the United Kingdom introduced the mandatory yield-at-entry rule at circular junctions, which led to the birth of the modern roundabout. Safety is the hallmark of modern roundabouts and they are popular in certain parts of Europe and Australia. The first modern roundabout in the United States was built in Nevada in 1990 and their number is steadily rising since then: 38 in 1997, more than 2,000 in 2010, and over 3,700 at present. There's still initial resistance from the public, but public attitude toward a roundabout changes favorably after the construction. Hundreds of roundabouts are expected to be built each year in the United States. This study presents a microscopic simulation modeling and safety analysis of the modern roundabouts.

 Bio: Dr. Nezamuddin is an assistant professor of civil engineering at Valparaiso University in northwest Indiana. Prior to joining Valparaiso University in August 2013, he was a research fellow at the Center for Transportation Research at the University of Texas at Austin from 2011 to 2013, where he worked in the areas of dynamic network modeling, traffic operations and microscopic simulation. Currently, he is working on microscopic simulation modeling and safety analysis of roundabouts. Dr. Nezamuddin received a Ph.D. (civil engineering) from the University of Texas at Austin and B.Tech. (civil engineering) from the Indian Institute of Technology Delhi, New Delhi.

Potholes or Tolls? Perspectives on Transportation Finance

Speaker Dr. Joseph Schofer, Professor of Civil Engineering &; Transportation and Associate Dean, McCormick School of Engineering, Northwestern University

Everyone is talking about the need for more funding for infrastructure – mostly highway infrastructure. In this discussion we will consider the need, how we got here, the options – real and imagined – and how we might address the problem.

Bio: Joseph Schofer is Professor of Civil and Environmental Engineering and Associate Dean of the Robert R. McCormick School of Engineering and Applied Science at Northwestern University. His research and teaching focus on transportation policy, particularly understanding and supporting decision making for transportation and other infrastructure systems investments and operations, needs for and use of data and information, learning from experience, and the role of transactions in decision making. Schofer is a National Associate of the National Research Council of the National Academies, a life Member of the American Society of Civil Engineers, Chair of the Transportation Research Board (TRB) Data and Information System Section and its Task Forces on Data for Decisions and Performance Measures and Development of Freight Fluidity Performance Measures. He also serves as a member of the Pace Citizen's Advisory Board and the Transportation Committee for the Chicago Metropolitan Agency for Planning (CMAP). Professor Schofer received the TRB Roy W. Crum Distinguished Service Award in 2011 in recognition of outstanding achievement in transportation research.

Schofer earned his B.E. degree in Civil Engineering from Yale University and his M.S. and Ph.D. in transportation engineering from Northwestern.
