A new elevator group control system is proposed. The system learns dynamic traffic flows by analyzing passenger traffic without prespecified patterns. A genetic algorithm continuously generates dispatch functions according to changes in passenger traffic. By considering the status inside elevators, the directions of passenger movement, and the number of waiting passengers, the system occasional...

An analytical investigation of a half-car model with passenger dynamics, subjected to random road disturbance, is performed. Two diierent methods of deening the performance index for optimal controller design are proposed. Nondeterministic inputs are applied to simulate the road surface conditions more realistically. Results obtained illustrate that using an optimal state-feedback controller, w...

With the rapid development of technology, the comfort of service has become an important issue. Air travels, especially long distance, may cause both physiological and psychological discomfort to passenger. Passenger comfort is clearly a main factor in user’s acceptance of transportation systems. Sleeping is one of the common activities during the long haul flight. In this paper, subjective and...

On the basis of relative theories of complex network, a high-speed passenger transportation network using Pajek software is proposed and its topological characteristics as well as network structure are analyzed. Analyzed is also its reliability under two kinds of attacks, and suggestions on its construction recommended. The research in this paper helps to complete the overall network structure ...

Previous work has led to the development of a crash energy management (CEM) system designed to distribute crush throughout unoccupied areas of a passenger train in a collision event. This CEM system is comprised of crush zones at the front and rear ends of passenger railcars. With a consist made up of CEM-equipped cars, the structural crush due to a collision can be distributed along the length...

World War II began on September 1, 1939 with the German invasion of Poland. By early May 1940, German troops had overrun the Netherlands, Belgium, and Luxembourg; soon thereafter Germany broke through the French defensive forces near Sedan. Political lethargy, a poor communication system and many mistakes accelerated the downfall of the French army. By the end of May approximately 350,000 Frenc...

Recent years have witnessed significant efforts in deriving and embedding semantic information in content for improved content retrieval, adaptation, and distribution. Relatively little work considers leveraging this semantic information in the infrastructure to better serve the needs of clients and achieve better cost-effectiveness of infrastructure resources. In this paper, we identify semant...

This paper deals with a novel three-level sensor fusion approach in order to detect and track cars and pedestrians. The underlying perception system is composed of a far infrared imaging device, a laser scanner and several radar sensors, which operate integrated into a BMW sedan. At three different levels fusion is applied to approach the generation of a robust and accurate description of the a...

Since September 11, 2001, airport screening procedures in the US have been continuously evolving. For example, the passenger screening process is now trying to strike a balance between security and customer service (i.e. minimizing wait times). This balancing act has important implications not only for passenger safety, but also for the financial stability of an airline industry that is faced w...
