| 摘要： | A wheel load measuring mat of total length 38 m, incorporating 96 capacitative strip weigh-in-motion (WIM) sensors was installed on a test track. A total of 612 test runs was peformed on 7 different articulated heavy vehicles, for a range of speeds between 8 km/h and 85 km/h. The wheel forces data was analysed to investigate the performance of the individual sensors and the design and performance of WIM arrays with up 6 sensors. The strip sensors were found to be very accurate and reliable. It was concluded that a good design for multiple-sensor WIM systems is to use 3 sensors, spaced evenly along the road. The sensor should be spaced according to a simple formula which depends only on the average traffic speed. The expected static axle load estimation errors for such a system are likely to be 30% to 50% of the errors of a single-sensor WIM system. |
