摘要： 观测并定量分析了车辆通过强制性减速带与半强制 性减速带的速度；建立了双车道橡胶减速带速度与距离二次多项式模型，及双向八车道半强制性减速带速度与距离指数型函数模型，描述了速度控制设施的减速效用；并对模型的可靠性和有 效性进行了验证。结果表明：研究的强制性和半强制性减速带均适合于同等路况及同类型减速带设置的情况。

Abstract: Observation and quantitative analysis on the vehicles’ speed decelerating by mandatory and semi-mandatory speed humps were carried out, and a quadratic polynomial model of dual carriageway rubber speed humps speed and distance was established. The exponential function model of two-way eight-lane semi-mandatory speed humps speed and distance was also established. The decelerating utility of speed control facilities was described. The reliability and validity of the proposed model were checked. Results show that the studied mandatory and semi-mandatory speed humps are suitable for the same type of roads and the same type of deceleration zone settings.

Key words: traffic engineering, mandatory speed humps, semi-mandatory speed humps, utility model, model fit
