Topic Area C: Traffic Management, Operations and Safety

 

Topic Area C is concerned with interurban highways as well as with urban roads, including traffic theory and modelling, traffic control and management, transport network analysis, information and communication technologies for traffic systems, and infrastructure management. Safety analysis and policy is comprehensively addressed in this topic area, both in relation to traffic safety, and as an important issue for all modes and intermodal transport. Public transport management, operations and control is covered as a part of this topic area. Regarding developing and emerging countries, there will be a close cooperation with Session Track H3.

SIG C2 – Urban Transport Operations

Objectives

The major objectives of SIG C2 are to strengthen and promote international scientific activities in the field of urban traffic control, management, and operations in WCTRS; and to encourage a closer commitment also by traffic engineers in a significant potential number from academics and practice to the society.

Background

SIG C2 was initially launched as SIG 15 on Urban Traffic Control at Nagoya University, Japan during its first meeting in November, 2011. Since its establishment, SIG 15 had been co-chaired by Hideki Nakamura (Nagoya University, Japan) and Manfred Boltze (Darmstadt University of Technology, Germany) until 2013.

According to the reformation of WCTRS-SIGs structure in 2014, the committee was renamed as SIG C2, and expanded its topic area to “Urban Transport Operations”.

The chair was taken over by Zong Tian (University of Nevada, Reno, USA) with Hideki Nakamura as co-chair from January 2014.

The chair was taken over by Keshuang Tang (Tongji University, China) with Zong Tian (University of Nevada, Reno, USA) as co-chair from July, 2016 (the WCTR 2016).

Azusa Toriumi (the University of Tokyo, Japan) was elected as the second Co-chair at the SIG meeting held during the WCTR 2019 in May, 2019. Keshuang Tang (Tongji University, China) and Zong Tian (University of Nevada, Reno, USA) remain to be the chair and the co-chair.

Activities

Major interest areas of SIG C2 include Intersection/junction design and traffic control, urban motorway traffic control, area-wide traffic control, urban traffic flow characteristics, highway design and capacity, traffic signal control under emerging technologies, etc.

Our SIG organizes two regular events per year. One is the annual meeting held in different countries, and the other is the gathering meeting/dinner at Washington D.C., USA, during the TRB (Transportation Research Board) annual meeting. In addition, our SIG organizes occasional events by taking advantage of opportunities of various international conferences. Major activities of SIG C2 from 2011 to 2019 are listed below.

SIG C3 – Intelligent Transport Systems

Objectives

The SIG aims are to:

• Promote the exchange of ideas, methodologies and applications of Intelligent Transport Systems (ITS) through regional meetings, international scientific collaborations and sessions at the WCTRS conferences.
• Facilitate the formation of international research teams to unite their effort for conducting research programs on ITS and cooperative ITS.
• Promote closer linkages between the research communities and institutions dealing with ITS.

Background

A proposal for creating a Special Interest Group C3 on Intelligent Transport Systems was tabled in the WCTRS Scientific Committee meeting in Washington DC in January 2014 and was accepted during the WCTRS Scientific Committee meeting in July 2014.

Activities

Joint SIG C2 & C3 meeting was held in Brisbane, Australia from 18th to 20th November 2014.

Selected papers from C3 track of the WCTR Conference will be published in the International Journal of Intelligent Transport Systems Research.

The group is currently recruiting new members from countries not represented by current members of SIG C3.

Membership

Membership is open to academic, researcher or practitioner with research interest in the subject area; and who are committed to contribute to the topic and to support the preparation of the WCTR conferences. Please contact the chair if you are interested in joining.

SIG C4 – Traffic Safety Analysis and Policy

Objectives

The analysis of transportation safety is multi-disciplinary. Economists, psychologists, physicians, mechanical engineers, civil engineers, lawyers and other disciplines have contributed to the literature. Our SIG was formed to ensure that the area of safety research is promoted within WCTRS and also that the rather disparate nature of the different lines of research are brought together under one banner at the World Conferences. Currently the SIG has confined itself to organizing sessions at the World Conferences.

Background

The transportation safety Special Interest Group (SIG) grew from two special sessions at the fifth WCTR in Yokohama in 1989. The SIG has organized multiple sessions on safety at every WCTR conference since the sixth WCTR in Lyon, France in 1992.

Activities

How safe is safe enough?, User safety perceptions and psychological reactions, crash statistics, the acceptability of crash risks, the analysis of crash locations, policy options, the role of insurance and liability, modal safety performance and safety measurement, international comparisons, policy and program evaluation, valuation of statistical life saved, crash costs, evaluation of emergency response, and safety management evaluation. The only real exclusion is consideration of “hard” engineering such as design of automatic train control, construction of crash barriers and the like, although we do welcome discussion of the economic effectiveness of such devices.

The safety track organized by the SIG has grown to be one of the largest areas for paper submissions at the WCTR. We have organized at least six sessions at every WCTR since Lyon in 1992. For the 11th WCTR in Berkeley, USA in 2007, we received 62 initial abstracts, and this resulted in 40 full papers being accepted and ultimately 33 papers were presented in eight sessions dealing with all aspects of safety. The Traffic Safety Center at the University of California-Berkeley sent a reporter and photographer to the sessions, and their write up of the events and the papers presented was in their newsletter and on their web site.

The SIG puts great emphasis on giving close personal attention to people who submit abstracts to the safety track. Consequently, we encourage many people to come to the WCTR, and by working closely with presenters we have never experienced any cancelled or poorly attended sessions.

Membership

The SIG is aimed at: government officials, industry representatives, medical personnel, economists, psychologists, and policy oriented engineers. In general we do not focus on “hard engineering” such as component design and highway geometry. Such researchers are well served by other professional forums. There is no fee for joining the SIG, but please register your interest with the contact information shown below to ensure that you receive notifications of calls for papers, and information on the sessions organized by the SIG.

Contact

The SIG is co-chaired by Dr Wael Alhajyaseen, Assistant Professor at Qatar Transportation and Traffic Safey Center, Qatar University, and Geetam Tiwari from IIT.  All correspondence is dealt with by Professor Tiwari.
