Guest Editorial Introduction to the Special Issue on Applications and Developments of Novel Technologies in Intelligent Transportation Infrastructure Systems

The service life and service quality of transportation infrastructures are crucial for the regular function and public safety of transportation systems. Thus, the intelligent and accurate evaluation, prediction, and analysis of transportation infrastructure service conditions have always been hot topics for transportation engineers, where such problems are sometimes hard to be solved using traditional approaches, considering different factors including complex traffic conditions, severe environmental conditions, etc. In recent years, intelligent technologies, including advanced sensors, novel artificial intelligent approaches (deep learning, etc.), the IoT-based monitoring and analysis platform, auto piloting, green energy, synergistic technologies, and systems integrating both traffic and infrastructures monitoring, have emerged as powerful tools in transportation engineering area. These efforts have greatly advanced the service convenience of public transportation, prolonged the service life of transportation infrastructures, and improved the efficiency and safety of transportation systems.
