摘要:

以双向四车道高速公路行车道封闭施工区路段的车辆实测速度数据为分析对象,利用单样本K-S 检验方法对各检测断面大型车、小型车的车速分布形式进行了检验, 利用概率密度曲线分别拟合了不同检测断面大型车、小型车的车速分布,定量分析了施 工区内不同交通控制区域的车速分布形式及其变化规律,并分析了不同交通控制分区对 车速分布的集中趋势和离散程度的影响.结果表明,高速公路施工区路段车速服从正态分布,施工区交通控制分区对车速集中趋势和离散程度影响显著.研究成果为高速公路施工 区交通安全管理和车速控制提供科学依据和数据支持.

Abstract:

On the basis of the analysis for collected speed data in carriageway lane closure work zone on dual- way- four- lane freeway, the distribution forms for collected speed sample data of trucks and cars are tested by single sample K-S test, and the speed distribution models of trucks and cars on work zone section are developed separately by probability densities curve. The speed distribution form and variational rule in different traffic control divisions of work zone is analyzed quantitatively. The effect of different divisions on the central tendency and dispersion degree of the speeds is analyzed. The research results show that the speed sample is normal distribution, and the traffic control divisions of work zone have significant impact on the speed distribution parameters. The results can provide a scientific basis and data support for safety management and speed control of work zones.

Key words: traffic engineering, work zone, vehicle speed, distribution characteristics, normal distribution, fitting model
