| 摘要： | The primary objective of this second phase is the further development, demonstration and field evaluation of a permanent dual purpose bridge weigh-in-motion and health monitoring system over an extended period of time. Calibrated test truck results demonstrated that the proposed algorithm can accurately predict vehicle speeds, and that even if the speed is exact other factors can contribute to the inaccuracy of the algorithm. The research has also been applied to a large continuous traffic data-set consisting of 385 days, providing information including GVW, truck speeds, and ADTT for certain months. The GVW, speed, and time stamp of each identified truck has been saved and loaded to a website accessible by the Connecticut Department of Transportation. |
