Extraction Method for Traffic Information of Regional Road Network

  • Received Date: 07 Dec 2007
  • Publish Date: 25 Jun 2008
  • To extract the traffic information of regional road networks,a method was proposed to identify traffic states using the matter-element analysis theory.In the method,traffic states are taken as decision attributes,a characteristic information table of traffic flows is constructed based on road grades,time and traffic parameters,and the traffic flow characteristics are extracted using the rough set theory.Numerical results of a case study verifies the effectiveness of the proposed method.The proposed mothod applys to traffic state analysis on-line and to extraction of traffic information from historical databases.
