Computing the fastest driving routes in the presence of varying traffic conditions is an essential problem in modern navigation systems. Most existing systems compute the fastest route based on the current traffic conditions, while ignoring the effects of potential dynamics at a future moment. To solve this problem, a time-varying hierarchical graph model is presented for structuring the urban road...
A novel analysis method for systems engineering based on wargaming technology is proposed. First, the essential factors and procedures of wargaming are introduced. Then, the systems engineering method based on wargaming is analyzed. At last, the systems modeling, simulating, and analyzing procedure is described in details by illustrating a living example. The characteristics and advantages of this...
The characters of fixed block system and moving block system are introduced . Based on the concept of moving block, the way to calculate the subway trainpsilas time interval is proposed after the compare with the fixed block and quasi-moving block. The formulation for the time interval under three signals are introduced, the simulation and the analysis are done.
