The International Symposium on Frontiers of Road and Airport Engineering (iFRAE) was started by College of Transportation Engineering of Tongji University. The symposium was first held in 2011 and then biennially since 2015. The 4th iFRAE will be held in Shanghai from October 25th to October 27th, 2019.

As a key component of smart cities, the transportation system is moving toward intelligence. The new generation of intelligent transportation infrastructure requires efficient system, durable structure, safe operation, and comfortable travel experience. Intelligent pavement technology was therefore developed, it has key functions of self-monitoring, automatic analyzing, self-adaptation, information interacting and continuous energy supplying. However, intelligent pavement is a sophisticated system, there is no practice-ready technology in this field. Its development involves intensive interdisciplinary collaboration of transportation engineering, operational management, automobile engineering, information science, civil engineering, materials engineering, etc. The 4th iFRAE will focus on the topics of architecture of smart road and airport, smart pavement materials and structures, safety technology for smart road, and sustainable pavement technology, which aims at promoting the upgrade of transportation infrastructure construction and technology. We sincerely invite researchers and scholars from around the world to join us at this conference and share your expertise or technologies.
