    Abstract: Maritime transportation is one of the most important modes of freight transportation. The navigation industry has been developing rapidly and the number of ships is increasing day by day. However, the navigable waters are limited, and the increase in the number of ships will inevitably increase the ship traffic density in navigable waters, leading ... Show More

    Abstract: NB port has proposed to build a new NBGB terminal for production needs. The navigational environment of NB port is complex, and the ships between adjacent terminals have obvious influence on each other when entering and berthing. In order to verify the feasibility of the proposed terminal's design vessel type entering and berthing, to fully reflect... Show More

    Abstract: The kinematics equations of longitude and latitude have singularities in polar of the earth. To solve the problem, a solution called the quaternion form of longitude, latitude and heading kinematics equations was created and introduced in the paper. The key point of the solution is to define an instantaneous great circle for a moving particle. To a... Show More

    Abstract: Due to the relatively small, confined space and large occupant loads in railcars, the fire protection and life safety in railcar is greatly concerned in the public transportation industry. The object of this study is to evaluate the emergency evacuation from railcars of a metropolitan railway system in the United States as part of the fire hazard a... Show More
