This paper introduces a kind of simulation testing system scheme for train-borne controller and applies it to the simulation testing system of the controller. Besides, it elaborates the system structure, interface type and key module of the hardware realization. The simulation testing system for train-borne controller is completely built, and plays a vital role in the train-borne controller simulation...
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...
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...
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...
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...
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...
This paper presents an innovative approach to investigate the inner mechanism between traffic status and crash potential based on High Definition Monitoring Systems (HDMS) data. HDMS records delicate vehicle trajectory data and characteristic details. Matched case-control method and Support Vector Machines (SVMs) were employed to identify risk status. The grid search method was utilized to find the...
For strengthening the effective supervision of key vehicles' illegal driving which are not in accordance with the prescribed routes, and to prevent and reduce the road accidents, this paper puts forward a method of the active discrimination of key vehicle's not-according-to-the-prescribed-routes based on the gate system's passing through information. Through analyzing key vehicles' passing records...
Either in China or other countries, there are highway construction ordinances. These ordinances require contractors to make evaluation system and submit report of construction impact on environment. It is also required that contractors need to forecast and analyze air quality in construction and operation process. However, detailed analyze method and numerical requirements. This article calculates...
After 30 years of rapid development, the total mileage of Chinese expressway has exceeded 100 thousand kilometers, and it has ranked first in the world. In the process of expressway construction and operation, the toll collection technology has also changed continuously with the development of information technology. The paper analyzed the development process of toll collection technology in China...
Road traffic accident is a serious threat to human life and safety of living environment. In this paper, a new road traffic accident prediction model (TAP-CNN) is established by using traffic accident influencing factors, such as traffic flow, weather, light to build a state matrix to describe the traffic state and CNN model. This paper uses samples to test the accuracy of the new model. The experimental...
The rapidly growing software content within the vehicles continue to make automotive systems more intelligent through the addition of software enabled electronics. A plethora of change in the automotive industry is largely driven by the embedded software technology. The Advanced Driver Assistance Systems are one of such innovations of technology which are gaining widespread momentum in today's ever...
In recent years, the road accidents have increased significantly. One of the major reasons for these accidents, as reported is driver fatigue. Due to continuous and longtime driving, the driver gets exhausted and drowsy which may lead to an accident. Therefore, there is a need for a system to measure the fatigue level of driver and alert him when he/she feels drowsy to avoid accidents. Thus, we propose...
The passenger flow data of urban rail transit (URT) network has the characteristics of large scale, fast-update, multi-mode, difficult to identify and great value, the same as Big Data. It is meaningful and effective to use big data visualization in passenger flow analysis. In this paper, with high visualization frameworks, the massive data of passenger flow in Shanghai Metro network is highly graphical...
In Japan, public transport such as bus services play an essential role in providing the growing aging population with mobility. However, both public and private Japanese bus services are in a precarious position with many of them running at a deficit due to the existence of convenient alternative means such as private cars. Therefore, this research proposes a new model to predict bus user demand based...
Increased number of container shipping nowadays, brings new challenges for container terminal to improve their operational performance. In addition with the increase of competition between ports, optimal and integrated planning will help terminal to face those challenges. This research studies about optimizing an integrated planning of the container terminal in Indonesia, using a bi-objective optimization...
Accidents and other emergencies are the direct cause of the impact on Urban Rail Transit operational safety and reliability. The Operation Control Center (OCC) is the first-line command organization for the operation and management of urban rail transit. How to deal with the characteristics of unexpected events in urban rail transit quickly and accurately according to the emergency plan prepared in...
The arrival times of buses are often hard to predict due to variation of real time traffic conditions, deployment schedules and traffic incidents. The provision of timely arrival time information is thus vital for passengers to minimize their waiting time and improve riders' confidence in the public transportation system, directly promoting more ridership. Multiple buses are commonly observed to arrive...
