Improvement of Testing Mode for Overload Detection Station

研究超限检测站检测模式改进问题,结合超限检测站固定阈值检测模式下出现的待检车道处排队长度过长影响主线交通正常运行等问题,提出以动态称重阈值调节检测模型代替超限检测站固定阈值检测模式。首先,分析超限检测站固定阈值检测模式下的检测弊端,然后提出了多车型自适应性动态称重阈值模型,分析了动态称重阈值调节检测模式下超限检测站的工作原理,并建立了超限检测站仿真模型。最后,以国道马场路超限检测站为例,对比仿真了两种检测模式下超限检测站的工作过程,仿真结果表明,动态称重阈值调节检测模式为超限超载运输车辆的管理工作提供了依据。

This paper presents an improved testing method for overload detection station. The detection mode with fixed threshold is replaced by the detection mode with variable threshold. The testing abuse of the detection mode with fixed threshold for overload detection station is analyzed, and an adaptive dynamic weighting threshold algorithm with variable threshold is presented for multi - type trucks. By taking the overload detection station on the racecourse road of the national highway, the algorithm is simulated. Simulation result shows that, compared with the traditional detection mode with fixed threshold, the proposed detection mode with variable threshold can improve the manage- ment of the overrun and overload transportation vehicles.
