Vehicular Computer Clouds (VCC) would be expected to play a major role in the Intelligent Transportation System (ITS) in the near future. While it is clear that the VCC concept raise exceptional security challenges. Generally speaking, most attacks come from operators. So it is important to design the novel VCC security scheme based on operator's attributes. In this paper, we develop the Fuzzy Operator-Attribute-Based...
Compared with the vehicle monitoring system that implements the management in physical entity dimension of road traffic, this paper presents a vehicle monitoring system based on the Internet of Things. Through the control of the vehicle in the virtual information space, it achieves accurate and intelligent vehicle management. 5 layers framework of the system and its working principals are described...
Vehicle monitoring technology based on the video image due to its features of easy maintenance and easy implement is concerned in recent years. Vehicle tracking is one of the key technologies to achieve video vehicle monitoring. How to achieve real-time vehicle tracking is the key and difficult problem at home and abroad. A method of Kalman tracking based on virtual loop is proposed in the paper....
This paper first analyzes the idea and target of urban public transportation emergency command system platform's (UPTECSP for short) construction, and then designs the system platform structure, and further detailedly designs its applications functions. There are design ideas and methods provided to build UPTECSP and achieve the emergency response capability of public transport system as well as promote...
Supposed the perception of traffic information and the controlling decision of vehicles are correct. The delay of controlling actions is researched in the paper, and the function of driver non-response probability is advanced. Based on the function, the timing curve of divers' response is made. Then the risk model of Rear-ends accidents is established to evaluate the probability of Rear-end accident,...
With the increasing vehicle use on the road, the collection, processing and transmission of data flow within and outside these vehicles are increasingly complex. These data is often important and sometime critical for drivers and passengers, particularly for remote monitoring and control applications. There are various forms of vehicle data and hence various types of networking used in different vehicle...
Based on Component Mode Synthesis method, the vehicle-bridge interaction problem of a concrete-filled steel tubular tied-arch bridge was analyzed. The mathematical model assumed a finite element representation of the bridge together with beam, shell, and link elements. And the vehicle simulation employed a three dimensional linear vehicle model with seven independent degrees of freedom. A well-known...
With xPC Target we can convert a PC compatible computer into a real-time system and build a hardware in-loop test bench of ESP system based on CAN bus technology. It will be more convenient and faster than traditional way. Since there is not a drive module of CAN PCI-1680U which could be invoked directly in xPC Target, by using S-function, the article compiled a drive module which can be invoked in...
The electronic stability control system is one of most advanced active safety technology for modern vehicles. It enhances vehicle active safety effectively. The control algorithm of combination with logic gate and PID control is brought out. The PID parameters are produced by logic gate control and the wheel brake torque to keep vehicle stabilization is outputted by PID method. The method possess...
To solve capacitated vehicle routing problems (CVRP), a modified differential evolution (MDE) was employed, which was derived from the differential evolution (DE) and incorporated with the genetic reproduction mechanisms, namely crossover and mutation. The Greedy Subtour Crossover (GSX) was employed to generate an offspring to denote the difference of the parents. A modified ordered crossover (MOX)...
A modified genetic particle swarm optimization method (MGPSO) is employed to solve the capacitated vehicle routing problems (CVRP). MGPSO was derived from the standard particle swarm optimization (PSO) and incorporated with the genetic reproduction mechanisms, namely crossover and mutation. MGPSO employs an integer encoding and decoding representation, which is suitable for combinatorial optimization...
