This paper analyzed the interactive pattern of traffic flow of three macro regions: urban, suburban and outside city based on real Beijing expressway's toll collection data. The method to calculate traffic volume between large OD regions were presented and a series of experiments were done to find out specific relationship on traffic volume of these large OD regions in different time spans. Some advices...
A new 3D platform is build in the self developed WebCAD system, used for multiple user collaborative design. As an extension of the WebCAD system, the collaborative 3D CAD system proposes a collaborative Boolean operation method. With the method complex physical objects can be easily obtained through Boolean operations of some elemental entities. With the new system, geographically distributed designers...
