The applications of Vision-Language Models (VLMs) in the fields of Autonomous
Driving (AD) and Intelligent Transportation Systems (ITS) have attracted
widespread attention due to their outstanding performance and the ability to
leverage Large Language Models (LLMs). By integrating language data, the
vehicles, and transportation systems are able to deeply understand real-world
environments, improving driving safety and efficiency. In this work, we present
a comprehensive survey of the advances in language models in this domain,
encompassing current models and datasets. Additionally, we explore the
potential applications and emerging research directions. Finally, we thoroughly
discuss the challenges and research gap. The paper aims to provide researchers
with the current work and future trends of VLMs in AD and ITS
