IWCTS 2022 Workshop

The 15th International Workshop on Computational Transportation Science (IWCTS 2022) is particularly timely given the prominence of human mobility data, such as probe data from cell phones and connected automated vehicles, volunteered geographic information, and other sensing data. This unprecedented access to sensing data of mobility, and of integration of this analytics into smart cities management has led to innovations in intelligent transportation systems, building information management, and urban planning. Due to the scale of these data, these developments are deeply computational.
We will build upon the success of previous workshops to continue to focus on computational approaches for (not limited to):
  1. Sustainability: Socioeconomic and environmental impact, mitigation strategies (e.g. emission analysis and reduction, decarbonization, alternative fuels, transportation equity, and environmental justice.
  2. Smart City Operations: Resiliency during extreme weather events (e.g. floods, tornadoes, etc), Intelligent Transportation Systems (ITS), Connected and Autonomous Vehicles (CAVs), Building Information and Energy Modeling (BIM/BEM), electric grid management, decision support, and optimization.
  3. Infrastructure Sensing: Digital Twin technologies, urban sensing infrastructure, edge computing, Internet of Things (IoT) devices.
  4. Human Dynamics Analysis: Modeling and simulation of population and freight movements, dynamic routing algorithms, computational traffic flow models and control algorithms, and the role of transportation in the smart city.
We welcome research papers from computer sciences, geosciences, transportation sciences, urban sciences, social sciences and other related sciences which address the above-mentioned focus areas. We will be organizing a panel alongside paper presentations / keynote. We seek to invite eminent people from industry, academia, and laboratories.

A Multi-Commodity Air Freight Origin-Destination Demand Analysis

Dr. Peter Vovsha
Dr. Rajesh Paleti

ABSTRACT: Increasing volumes of air freight have created new challenges for airports and the cities and regions that house them, necessitating the development of models that are better able to estimate demand. This paper presents a novel analytical framework to forecast air freight tonnage by commodity type between an origin-destination (OD) pair as a function of socio-demographic composition, employment by industry type, economic conditions, and airport density at the two ends of that OD pair. The proposed framework is comprised of three modeling components - (1) a binary selection model to determine OD pairs with non-zero demand in at least one commodity category, (2) a stochastic frontier model to analyze total air freight demand across all commodity types while accounting for inefficiencies in the system that may reduce the maximum output (i.e., demand), and (3) a demand composition that allocates the total demand across different commodity types. Each of these models was estimated using the 2017 Freight Analysis Framework (FAF) data. To evaluate the efficacy of this tool in practice a policy analysis was undertaken to quantify the air freight demand changes in the region surrounding the Dallas Fort-Worth International Airport under different scenarios. The results of this case study demonstrate the practical applicability of the proposed framework to a large international airport.

BIOGRAPHY: Rajesh Paleti is a Senior Research Scientist at Amazon and has 10+ years of experience in statistical inference, applied econometrics, and machine learning. His work includes several fundamental methodological contributions to discrete choice analysis consistent with utility-based microeconomic theory of consumer behavior. Rajesh is passionate about building data-driven models of human behavior informed by latest developments in data science, economics, and psychology literature. Rajesh published 50+ journal articles with 2,400 citations in leading econometrics journals. Prior to joining Amazon, Rajesh worked as a Research Scientist at Oak Ridge National Laboratory and Assistant Professor at Pennsylvania State University and Old Dominion University. Rajesh graduated from the University of Texas at Austin with a doctoral degree in Civil Engineering.

PAPER SUBMISSION GUIDELINES

All papers must be original and not simultaneously submitted to another journal or conference. The following paper categories are welcome:

  • Full papers (up to 10 pages): Original, unpublished research papers which belong to the scope of the workshop, i.e. computational transportation science and are not being considered for publication in any other forum.
  • Short papers and Position Papers (up to 4 pages): Papers describing the early research results on original work on computational transportation science. Authors must clearly state the ongoing and future work and the relevance of the results presented in the context of the scope of this workshop.
  • Demo Papers (up to 4 pages): Describing original systems for demonstration/presentation at the conference.

Papers must be in ACM SIG format (https://www.acm.org/publications/proceedings-template) (US Letter size, 8.5 x 11 inches) including text, figures and references. Accepted papers will be published in the ACM digital library under the condition that at least one author has registered for both the main SIGSPATIAL conference and the workshop, attends the workshop, and presents the accepted paper in the workshop. Otherwise, the accepted paper will not appear in the workshop proceedings or in the ACM Digital Library version of the workshop proceedings.

Please submit your papers to - https://easychair.org/conferences/?conf=iwcts2022

Camera-ready Paper Submission

There are three important things to make sure while preparing the camera ready papers for the workshop:

  1. Authors must address all the comments and concerns from the reviewers.
