The recuring rise of artificial intelligence and its progress drive the development of advanced transportation systems. Both the academia and the industry devoted themselves for smarter transportation in Taiwan. Models advancing the frontier of artificial intelligence has been proposed every year. How to adapt these approaches in Taiwan is a critical challenge. This article reviews recent papers where we first introduce existing image recognition, overlapping object detection, re-identification, and audio recognition models. Then, potential applications are proposed, including cross-camera tracking, high-density traffic tracking, low visibility detection, and noisy vehicle detection. We also consider the feasibility of mixed traffic flows in Taiwan. We hope that this article sparks more ideas on applications of intelligent transportation.
