With the rapid development of the metro, the human error factors is playing an important role in the process of metro operation, especially when the Automatic Train Protection (ATP) system occurs fault. Based on the 5M model, this research adopts the methods which are literature review and field survey to identify and classify the human error factors during the metro operation without ATP. Eventually...
This study attempts to make use of traffic behaviour on the aggregate level to estimate congestion on urban arterial and sub-arterial roads of a city exhibiting heterogeneous traffic conditions by breaking the route into independent segments and approximating the traffic flow behaviour of the segments. The expected travel time in making a trip is modelled against sectional traffic characteristics...
By identifying the status of traffic congestion, the irrationality of road network planning can be made clear to propose comprehensive optimization measures. This paper used traffic congestion spatio-temporal identification model considering the changing nature of traffic congestion with time and space, to reflect the traffic congestion degree of a section, a route and a whole network. The application...
In the rail transit, there are many devices in operation which will produce a more intense electromagnetic interference. And some devices are more sensitive to electromagnetic interference, and therefore will not work properly, or even malfunction. So electromagnetic compatibility is the problem that must be considered and solved during the design of rail transit equipment system. According to the...
Although the navigation safety has been greatly improved nowadays, automation of ship driving are not achieved completely as the automation of collision avoidance has not achieved perfectly. This paper mainly research on ship domain modeling and application for ship collision avoidance. The novel achievements are that it proposed a 3-d model of ship domain and improved the danger judgments of collision...
Shrinking reserves of natural resources as well as incisive environmental pollution oblige humanity to rethink its generally favored propulsion concept: in the last decade electro-mobility as a refurbished technology gained greater significance once more. Due to political course setting, many German cities are testing Electric Vehicles (EV) especially in public bus transport. To get to the bottom...
Optimal energy management strategies of hybrid vehicles are computationally expensive when considering the entire trip ahead rather than a short upcoming horizon. Considering the entire representative trip is already needed in concept design stages of the vehicle. In order to come up with an appropriate design while minimizing the total ownership cost the energy management strategies must already...
Electrification offers a great potential for commercial vehicles to significantly reduce energy consumption as well as CO2 and pollutant emissions during operation. The project eLift demonstrates the potential of the electrification of a special-purpose vehicle. A conventional diesel catering truck with hydraulic auxiliary lifting unit is to be replaced by a more efficient electrically driven truck...
The spatial layout of an urban system has important effects on the indoor cooling load and outdoor thermal comfort especially for regions with extreme hot weather. These effects, however, are difficult to analyze in the presence of human adaptation to thermal stress. This paper presents an integrated model to analyze the effects of urban geometry on indoor cooling load and outdoor thermal comfort...
The paper proposes a study of different control techniques e.g. Backstepping, Fuzzy-PID, and PID used along a predefined 2D path from the A∗ path planning algorithm. The control techniques were applied to an X8 quadcopter model and investigated upon by analyzing the RMSE of each output motion. Through the simulation comparison, Fuzzy-PID proves to be the superior performer with the lowest RMSE value...
Storage efficiency of the automated warehouse directly affects the overall efficiency of tobacco logistics, in order to reduce the idle rate, a slotting optimization method is proposed by the combination of fault tree analysis and field test in this paper. First, the Pareto diagram is used to analyze the warehouse slotting usage situation. Then, obtain the key factors of the idle goods allocation...
In the era of big data, massive data has been accumulated in integrated application platform of traffic management of public security. Confidential information leakage is one issue of great importance in the process of data collecting, storing, processing and utilizing. In this work, we propose an anomaly detection approach for the prevention of confidential information leakage. Assume that users'...
A Bayesian network optimization algorithm is proposed for the problem of combat intention identification of aerial group targets. The external characteristics of the data link of the targets group are extracted as the network nodes. Then the initial Bayesian network model is established with the network nodes and conditional probability tables. Simulating to get the sample data set, and evaluation...
This paper reports the motion control of a wall climbing robot. The robot has a pair of driving wheels and a coaxial propeller thruster. Two wheels are used for running on walls, and the thruster located on a gimbal mechanism is controlled corresponding to the orientation of the robot and the slope angle of the wall. The orientation control of the gimbal mechanism is newly proposed, and is experimentally...
