In order to solve problem of the road traffic accident scene fast and high accuracy investigation, a GPS VRS, GIS road database and stereo vision integrated traffic accident scene investigation and management framework is proposed. Firstly, the GPS VRS technique is adopted to determine the initial location of the traffic accident which is used to query the road based map of the traffic accident from...
The following topics are dealt with: rainfall forecast; GPS; sequence analysis; image coding; climate change; water environmental quality analysis; remote sensing; soil moisture estimation; optimization; evolutionary game model; Kalman filter; time series model; electrochemical heterogeneous catalytic process; video processing system; urban water management; geographic information system; fuzzy neural...
A recently approach on tobacco delivery and routing daily schedule is to employ single-multi information from mature technologies such as GIS or GPS. An important challenge arises when using more than one information resources: how can one ensure the consistent usage of data collected in a coherent fashion for the comprehensive tobacoo delivery platform? Tobacco industry requires a comprehensive delivery...
To effectively integrate the logistics resources and improve the operation efficiency of the forth party logistics (4PL), this paper provides a service-oriented 4PL operation mode with the integration of modern service management theory, logistics management and service-oriented computing technology based on the analysis of the requirement of 4PL operation mode. On the basis, the operation process...
Traditional travel information such as books, outlets and so on are popular, but they are not convenient, and part of them is out of time. Self guide mobile system provides new travel information gaining method. It eliminates language obstacle, presents abundant, real-time and position-oriented travel information automatically. Moreover it integrates geography information system, multimedia, Global...
In geographical information engineering, height anomalies must be known in order to convert GPS ellipsoid heights into geodetic heights. There are many conversion models, such as polynomial, BP neural network and multi-quadrics fitting. Because the quasi-geoid is an irregular geometric object, every method has both advantages and disadvantages, and is appropriate to different conversion patterns....
In order to enhance level of vehicle guidance system (VGS) in China, the framework, subsystem and critical technologies of VGS were studied, and geographic information system (GIS), Global Positioning Systems (GPS), etc. were applied into corresponding subsystems. Paying attention to the subsystem of route optimization, the mathematical model of road network was built. The storage structure of road...
In this paper, we propose a novel route guidance algorithm that provides better wireless network availability. Using a GPS device, geographical information is considered to select a short geographical path while ensuring the maximum covered distance and the minimum handovers number. An efficient algorithm is derived to tackle the problem in polynomial time. Our solution is optimal and well suited...
After a full analysis of the "CDS (cigarette-distribution system)" situation, this paper researched the application effect of RFID (radio frequency identification) in the CDS by comprehensively considering the safety, tracking, visualization and time-effective problems in the process of cigarette-distribution and constructing a new cigarette-distribution mode and its information system model...
