In the present study we conduct analysis of methods and models of origin destination matrices reconstruction with regard to urban transport processes, we point out their advantages and disadvantages. As a result of the analysis the relational method of OD matrices reconstruction is chosen and the trilinear model (EVA) is considered as the most applicable for OD matrices reconstruction. To show the...
Traffic incidents such as crashes have significant impacts on urban expressway operation. The roadside service and operational efficiency of urban expressways could be improved based on a well-developed incident duration prediction model. In this study, a hybrid approach that combines Cox regression and random survival forests algorithm is developed to establish incident duration analysis model. The...
Estimation of the energy consumption rate for electric vehicles (EVs) plays a critical role in a variety of EV eco-driving applications and systems. As a result, quite a few studies have been dedicated to the development of estimation models. To improve the predictive and real-time performance of EV energy consumption rate estimation for eco-driving applications, we proposed herein a hybrid modeling...
The article considers the experience of OLAP-technology in solving optimization problems of the city transport system. The authors proposed a conceptual decision support scheme to optimize the transport-road network parameters. The developed system provides the possibility of intelligent analysis and decision-making based on OLAP-technologies and simulation models.
This paper aims at studying the changes in the number of pedestrians who go across road in “Chinese ways” to discover the evolution laws and behavior influential factors. The model including pedestrians crossing behavior analysis without supervising are established, and the profit matrix is acquired by intercepting the scene of “Chinese style road crossing”. The influence of variety of decision-making...
Multi-level analytic-imitational method is proposed to find the optimal allocation of the financial resource dedicated to road surface quality improvement for traffic network sectors (roads). Using the proposed method aims to reduce the average time of travel through the network. The test results of the method of optimization allow us to conclude the feasibility of further development.
The aim of this paper is to present the state-of-practice in transport modelling in Budapest. BKK and its subcontractors created an integrated multimodal transport model (MTM) as a result of a three year process. This model is based on large-scale data gathering process and it will provide support for decision making processes. More solid, evidence based decisions can be made with the help of this...
An intelligent device system for the automatic notification of traffic code violations is proposed. Then an analysis of the demand potentially interested in the new system is conducted based on both random utility and neural networks models.
With economic development and social progress, geographic information science is playing a more and more important role in tourism development. Many spatial analysis methods have been used in planning and design of scenic development programs. In this paper, the application of geographic information systems is illustratedfrom three perspectives. DEM model, Voronoi diagram and Space syntax are used...
The design, analysis and evaluation of protocols in cellular and hybrid networks requires realistic traffic modeling, since the underlying mobility and traffic model has a significant impact on the performance. We present a unified framework involving constrained temporal graphs that incorporate a variety of spatial, homophily and call-graph constraints into the network traffic model. The specific...
Critical Infrastructures (CIs) play crucial roles in modern societies and our reliance on their proper functioning even in the face of accidental failures and deliberate targeted attacks makes their protection of paramount importance. A notable characteristic of CIs is their interdependencies that may exist at many levels and facets of the infrastructure, and which may sometimes lead to unforeseen...
In this paper, both the qualitative and the quantitative analysis methods are used to analyze the scope of influence of twelve stations of Zhengzhou Subway Line 1 in the Zhengzhou West District and Central District on the surrounding real estate values. Moreover, the scopes of influence in these two regions were compared to find out the rule of influence, thus providing a reference for further study...
As the requirement of rural tourism from urban residents increases, the Rural Home Inn tourism develops rapidly with its unique spatial structure. Based on the analysis of the current development and the spatial layout rules of rural tourism, this paper proposes the urban-rural spatial structure of rural home inn and six models of its space format. By analyzing the case of the tourism development...
Traffic state is an important indicator and usually used for describing road network performance. Traditional traffic theory modeled traffic performance from fluid dynamics and time-series analysis. However, these models cannot obtain satisfactory result under real traffic situatuion, espcially macroscopic environment. From priori knowledge, within a discrete time interval, many of the vehicles that...
The ecological zone is the smallest unit perceived and relatively consistent in the ecological landscape, and it's also a group of symbiotic community geographically, reflecting the specific climate, soil, vegetation and ecological conditions. There're a number of unique top species, such as tropical rain forest, desert and other ecological domains in this unit. Owing to the continuous progress of...
With the development of industrialized societies, the volume of production and transportation for hazardous materials (hazmat) is constantly growing. Since hazmat is an obnoxious item, the people on both sides of a road don't want them to pass this way. Therefore, how to spread the risk among the network evenly should be considered. This is so called "risk equity" problem. This paper considers...
With the rapid development of expressway construction, environmental effects have also increased protrudes out from eco-environment, land utilization, hydrogeology and sound environment. Based on ecological footprint model, this paper analyses and compares the change of the per capita ecological footprint and biological capacity before and after constructing Yongdeng-Gulang (here-in-after, Y-G) expressway...
The theme is try to introduce the calculation software of fuel consumption for heavy truck which is based on Microsoft Access 2003 database management system and object-oriented visual programming language Visual Basic (VB) 6.0. It developed through the analysis of the important factors influencing heavy truck fuel consumption, the database of the actual running vehicle information, the compilation...
This thesis analyzes the characteristics of cold chain logistics and establishes the index system of the location of logistics distribution center. The gray comprehensive evaluation applies gray correlation analysis as well as the AHP and studies the location of cold logistics distribution center with the organic integration of the two methods. Finally it is proved with the combination of the case.
TraSMAPI (Traffic Simulation Manager Application Programming Interface) is designed to provide real-time interaction with Traffic Simulators, collect relevant metrics and statistics, and offer an integrated framework to develop Multi-Agent Systems. It is presented as a tool for the simulation of dynamic control systems in road networks with special focus on Multi-Agent Systems. The abstraction over...
