Technical Indicators and Safety Design of Freeway in High Altitude Area

Qinghai-Tibet Plateau has many special characteristics, such as low pressure and hypoxia, complex geological conditions, fragile ecological environment, and various bad weather conditions, which exerts a negative effect on highway construction and traffic safety. It is a huge challenge to build a safe and environment-friendly highway on the Tibetan Plateau due to lacking of mature experience around the world. Therefore, this book was supported by the National Science and Technology Support Program: highway construction technology in high altitude and cold regions to research the critical indicators and technologies. This book focuses on the driving behavior and typical vehicle characteristics in the high altitude area to put forward a series of geometrical indicators and traffic safety improvement measures, based on a great number of ground tests. Moreover, the relative achievements were applied to the demonstration project and validate the feasibility of indicators and countermeasures. It is of practical and leading significance for highway construction and improving the traffic level in the Qinghai-Tibet Plateau.

Jianbei Liu is the director of Intelligent Transport and Smart City Research Institute, CCCC First Highway Consultants Co., Ltd. She is a Ph.D. student majoring in Traffic Engineering at Tongji University, and received a master’s degree in Highway Engineering from Chang’an University in Xi’an, China. She has been working on highway design, interchange design, traffic safety research, and digital technology application for the past decade years. Due to her outstanding contributions, Dr. Liu has taken charge of a number of national and provincial projects and received great awards. Combining technical research and engineering design, she has published more than 30 papers on highway safety and highway geometry design, 7 standard specifications on highway construction, and 20 national/provincial scientific research projects.
