At last,the paper proposed the idea of how ACTRA system should realize the data share and scheme coordination with route guidance system,and of how traffic control center could realize the automatic division to further improve operation benefit.
In this paper,the Data Link of Automatic Vehicle Location System(AVLS) based on GPRS has been introduced and the key technology of accomplishing link is described according to the working flow of GPRS users.
At last the probe vehicle data of bus in Zhongshan City have been analyzed.
compare with data of the field testing,furthermore,the influence of self-vibration characteristic when primary structural parameters changed was discussd, the results of the amendatory model was calculated by finite element is near to the experimental data. and could reflect structural actual status basically. this calibrated finite element model can serve as a baseline in the long-term health monitoring and condition evaluation of the bridge in service.
The original data in excel testing files is extracted directly with Office Development technology,to form foundation data for highway quality inspection and evaluation. This technology can implement data share between testing and quality inspection.
