Talents are the cornerstone of the industrial development and play a decisive role in guaranteeing the maintenance quality. However, with the research on national rural highway, it is found that the staff team of maintenance has several problems, such as low level of education background and titles, the structural imbalance, the disequilibrium of supply and demand. The authors of the paper reveal...
Using the ARM processor and the embedded operating system uC/OS-II as a development platform for designing navigation systems. The system uses GPS systems to obtain the latitude and longitude of the vehicles, by conversion and map-matching to get the actual location on the map, and then the user enter the destination, calculated the shortest path by A* shortest path algorithm and showed on the vector...
Based on statistical analysis of site and facilities of The 2005 Aichi World Exposition, 1970 Oska World Exposition and the Hannover World Exposition, this work discusses the grades index of visitors control in peak time and instantaneous capacity control index when emergency measures are taken. Some suggestion for visitor management and controlling was proposed.
In order to relieve traffic congestion and accidents caused by vehicles merging into main road from ramp, the important influence factors of merging behavior were analyzed firstly. Then, traffic conditions under different traffic volume of ramp and main road and different length of acceleration lane were simulated by Vissim. According to security and efficiency evaluation measured by conflict intensity...
In order to represent the fuzzy attribute of traffic state, this paper first analyzed the characteristics and spread mechanism of traffic congestion on urban road network. Then a traffic state coefficient was introduced to measure the congestion level on road sections. On the basis of cloud theory, a fuzzy method of traffic state identification was proposed. By constructing judgment matrix, an analytic...
