The Symposium on Algorithmic Approaches for Transportation Modelling, Optimization, and Systems is an international forum for researchers in the area of algorithms and optimization methods to facilitate planning and operational management of freight and passenger transportation and traffic. ATMOS brings together researchers and practitioners who are interested in all aspects of algorithmic methods and models for transport optimization. The symposium provides a forum for the exchange and dissemination of new ideas and techniques. The aim of making transportation better gives rise to very complex and large-scale optimization problems requiring innovative solution techniques and ideas from algorithms, mathematical optimization, theoretical computer science, and operations research.
