Artificial Intelligence in Transportation
KDD 2018 Tutorial, London, U.K.

Abstract

Data-enabled smart transportation has attracted a surge of interest from machine learning and data mining researchers nowadays due to the bloom of online ride-hailing industry and rapid development of autonomous driving. Large-scale high quality route data and trading data (spatiotemporal data) have been generated every day, which makes AI an urgent need and preferred solution for the decision making in intelligent transportation systems. While a large of amount of work have been dedicated to traditional transportation problems, they are far from satisfactory for the rising need. In this tutorial, we systematically introduce the decision making (core planning) process in modern mobile transportation platform and the key emerging challenges in this process. We survey existing work on these challenges, focusing on the recent progresses in AI and data-driven solutions. Furthermore, we release a large-scale transportation benchmark and a related research platform for researchers who are interested in transportation AI. We aim to provide a general overview of the key problems, common formulations, existing methodologies and future directions. This tutorial will inspire the audience and facilitate transportation AI research.
