| Abstract: | Grid provides high quality computing resource for large-scale transportation simulation. Under the environment of grid, the accuracy, efficiency and availability of are transportation simulation promoted significantly. Based on the integration of massive history GPS data of automobiles and the combination of real time GPS data, the OD matrix of large-scale traffic network was estimated. By applying Web Service technology, the simulation on Internet as a service was provided. Using parallel computing, the capacity and the scalability of simulation computing were promoted. |
