Speaker:  Stephane Hess, Professor of Choice Modeling, Institute for Transport Studies, University of Leeds, U.K.

Abstract: Mathematical models of choice behaviour are used to understand people's choices across a range of topic areas, with transport being one of the most active fields. Their outputs form a key component in guidance underpinning government and industry decisions on changes to policy, infrastructure developments or the introduction of new services or products. In recent years, there has been a growing trend to seek to improve the behavioural realism of the models, often through bringing in ideas from behavioural economics and mathematical psychology. This presentations gives an overview of a number of key concepts in this area, showing the extent to which existing data supports the notion that the assumption of purely compensatory (and often linear in preferences) decision making is not representative of real world behaviour. The talk then focusses on whether (and how much) this matters for choice modelling research and real world transport planning, and identifies some key priorities for future developments.

Bio:   Stephane Hess is Professor of Choice Modelling in the Institute for Transport Studies at the University of Leeds. He is also Honorary Professor in Choice Modelling in the Institute for Transport and Logistics Studies at the University of Sydney, and affiliated Professor in Demand Analysis at KTH Royal Institute of Technology in Stockholm.

His main research interests lie in the use of advanced discrete choice models for the analysis of travel behaviour, primarily with the use of stated preference data. Here, Hess has made contributions to the state of the art in the specification, estimation and interpretation of such models, notably in a valuation of travel time savings context, while also publishing widely on the benefits of advanced structures in actual large-scale transport analyses.

Metra and Chicago -- Making A Difference in Chicago

Transportation Center Rail Group (Sandhouse Gang) Meeting


DONALD A. ORSENO,   Executive Director, Metra   and   BILL THOMPSON, CREATE Railroad Program Manager, Association of American Railroads

 Metra and CREATE move forward with ambitious plans for the future.  In October 2014 the Metra Board of Directors approved the first long-term capital plan in Metra's 30-year history. Metra, Amtrak and Norfolk Southern celebrated the grand opening of the Englewood Flyover in October. CREATE announced the availability of the Final Environmental Impact Study for the 75th Street Corridor Improvement Project. This $1 billion plus project that will address a major rail congestion point in Chicago will have a significant impact on freight and Metra and Amtrak fluidity in Chicago.  Don Orseno, Metra's CEO and Bill Thompson, AAR's Vice President in charge of CREATE will address these and other issues and answer questions on the future direction of Metra and CREATE.

Flexible Transit for Low-Density Communities

Transportation Seminar

SpeakerCharlotte Frei, PhD Candidate, Transportation Systems Analysis &; Planning, Civil &; Environmental Engineering, Northwestern University

Abstract: Demand for transport in low-density areas can be highly variable over time, and quality (or absence) of transit service may reinforce existing mode choices among travelers. Transit services that can flex with demand have been explored to address this variation. This paper describes a method to identify bus stop locations for a flexible service with characteristics of both fixed-route and demand-responsive transit. Once stops are identified, vehicle tours using actual origin-destination demand are constructed to evaluate relative operational efficiency. Simulations for a case study area in metropolitan Denver, Colorado and demand estimation results will be presented.  The methodology is appropriate to determine checkpoint locations and evaluate fleet allocation to structure flexible. The method can be extended to evaluate design of flexible transit in other low-density area; such future extensions will be discussed, particularly in the context of evolving vehicle technology and customer service expectations.

 Bio:   Charlotte Frei is a PhD Candidate in Transportation Systems Analysis and Planning at Northwestern University. Her research interests include travel behavior and public transit, with emphasis on topics related to transit mode choice. Charlotte earned a BS in Civil Engineering from the University of Texas at Austin.

"Microscopic Simulation and Safety Analysis of Roundabouts"


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.
