Relative Positioning of Vehicles Carrying Hazardous Materials Using Real-Time Kinematic GPS

Abstract

The accident of vehicles carrying hazardous materials occurring in downtown area has a possibility of secondary damage due to the hazardous material spill even after the primary damage of accident, and therefore incurs huge losses in economic and social aspects considering the extent and spread of damage. For minimizing the loss incurred by the accident of vehicles carrying hazardous materials, it is necessary to quickly detect and take action against the accident of vehicles carrying hazardous materials. A large vehicle carrying hazardous materials consists of tractor and trailer. To effectively and promptly detect the accident occurrence, the precise relative position, relative velocity, and attitude information between the tractor and trailer are required. In general, the GPS and INS are mainly used to obtain the position information and attitude

Estimation of Angular Acceleration By a Monocular Vision Sensor

“…Therefore, studies on the real-time detection and prevention of the accidents of vehicles carrying hazardous materials have been carried out. Kim et al (2013) proposed a detection technique for vehicles carrying hazardous materials using moving reference based Real-Time Kinematic (RTK) by installing Global Positioning System (GPS) receivers at a tractor and a trailer, respectively, as shown in Fig. 1.…”
