The European Electronic Toll Service (EETS) allows different possibilities for the overall system design of interoperable toll systems. We study the effect of the overall system design on the operational costs using a model based, holistic, executable specification. The model is set up to give an accurate description of the interdependences as seen in the German toll system. Two different scenarios...
Departure headway distribution is significant for intelligent traffic control and traffic simulations. Jilin, an ordinary large city, is selected in this paper to study the departure headway distributions. Experimental results show that the log-laplace distribution model fits headway data better for free flow traffic condition, while the log-logistic distribution model is more suitable on the peak...
Rail high-speed passenger lines (HSPL) have been developed rapidly in China; however, the traditional rail crew scheduling mode called responsible mode, in which crews are bundled with vehicles, is hard to adapt to the transit characteristic of HSPL. Moreover, the utilization of rail crew resources is commonly inefficient and the scheduling methods are generally behindhand. To reduce the pressure...
Vehicle axle structural design and optimization is an important part of the vehicle development process. Its strength is directly related to vehicle safe under impact. The design should consider the integrity, achieve the same database of design and analysis of the structural data, The parameters model of ATV's axle is set up based on the seamless integration technique of all the module of Pro/E platform,...
A reasonable layout of the logistics distribution system can significantly reduce business operating costs and improve logistics system operating efficiency. The operation characteristics and physical resources of third-party logistics and distribution system focused in this article, the key parameters of the distribution system operation efficiently and stably get summarized. Through simulation and...
This paper proposes a probability weighted ARX (PrARX) model wherein the multiple ARX models are composed by the probabilistic weighting functions. As the probabilistic weighting function, a `softmax' function is introduced. Then, the parameter estimation problem for the proposed model is formulated as a single optimization problem. Furthermore, the identified PrARX model can be easily transformed...
New driver assistance systems can have consequential effects on traffic flow. Investigative simulations are necessary for the design, optimization and evaluation of these assistance systems. Previous calibration and validation methods utilized either microscopic or macroscopic measurement data.This paper's purpose is to argue that the formerly held calibration and validation perspectives with regard...

Nowadays the greatest part of the efforts to meet fuel economy and to reduce pollutant emissions are directed toward the hybridisation of automotive drive trains. In particular the design of hybrid vehicles requires a complete system analysis including the control of the energy given from the on board source, the optimisation of the electric and electronic devices installed on the vehicle and the...
