Hongjun Pan holds BS Degree in Chemistry; MS Degree in Physics and PhD Degree in Chemistry. He is the Director of Nuclear Magnetic Resonance Laboratory at the University of North Texas, USA. He has published more than 25 peer viewed research papers in reputed journals and has presented several talks in international scientific conferences.
In our modern daily life, automobile vehicles are the most common transportation tools, however, collisions cause millions of people injury or death and billions of dollar property damage every year, safety is the top concern in automobile industry and researchers, great resources and efforts are focused on preventing collisions, but not much on reducing the severity of the collisions when they really happen. A new collision safer device is proposed to substantially reduce the impact force on the people and on the vehicles during the collision, lives can be saved and property damage can be reduced. The proposed collision safer device has one free rotation wheel installed horizontally at the vehicle lower front left and right corners, respectively, it can be also installed in the middle section of the bumper location as option; the wheels will be first contact of the vehicle when in collision; when the collision is non-perpendicular, the collision force component parallel to the collision surface of the collision will cause the wheel rotating and make the vehicle rolling slide along the direction of the parallel force component, therefore, the collision will be softer and less harmful, so lives could be saved and property damage could be reduced. At 45 degree collision angle, the effective impact force on the people and the vehicle can be reduced about 30%, such 30% impact force difference could mean life or death; at 30 degree collision angle, the effective impact force is half of the original impact force; and at 20 degree collision angle, the effective impact force is about one third of the original impact force, such dramatic reduction of the effective impact force will significantly reduce the severity of the collision, and reduce the collision injures and property damages. Millions of lives and billions of dollars for the property damages will be saved in the future if the proposed collision safer devices are installed on all vehicles in the future. This collision safer device is simple, low cost and can be installed on all types of vehicles. The proposed collision safer devices can be perfectly fit into the structure of the crumple zone of the vehicles and provide maximum protection for the occupants of the vehicles. The function of the proposed collision safer devices in most frequently happened collision situations are discussed.

Kongsu Yi obtained his BS and MS Degrees in Mechanical Engineering from Seoul National University (SNU) Republic of South Korea in 1985 and 1987, respectively, and PhD Degree in Mechanical Engineering from the University of California, Berkeley (USA) in 1992. He is currently a Professor at the School of Mechanical and Aerospace Engineering of SNU. He currently serves as a Member of the Editorial Boards of the KSME, IJAT, and ICROS journals. His research interests are control systems, vehicle dynamics, driver assistant systems and automated driving of ground vehicles.
Automated vehicles are expected to be the sustainable future for safe driving, efficient traffic, and reduced energy consumption. Almost every challenge concerning modern road traffic such as traffic jam, road fatalities, carbon emissions, and parking space can be solved by smart mobility system such as automated vehicle-based car sharing. Most of major automakers have already commercialized various advanced driving assistance systems (ADAS) to enhance driving safety and to reduce driving workload, and are planning to commercialize Level 3~4 automated vehicles for personal mobility from the year of 2020. As of 2018, automated vehicle-based smart mobility systems are operated in several sites and it is expected that smart mobility services with large fleets of automated vehicles will be available in 100 cities in the year 2025. Although still there exist many technical challenges concerning full automated driving in urban environments, there has been rapid progress in the field of automated vehicles. In this talk, technical issues and recent developments for automated driving in urban environments will be presented. A hierarchical structure for decision and motion planning for autonomous driving at unsignalized intersection has been developed. Based on real road driving data analysis an intelligent driver-veicle models for cross-first or yield has been developed. Index variables for target intension inference at intersection have been defined and interacting multiple model (IMM) based intention inference scheme has been developed. A target inrention inference-based decision and motion planning has been investigated via computer simulation and successfully implemented on an automated driving vehicles.
