普通国省道路况特征及其影响因素分析
Characteristics and Influencing Factors of Pavement Condition on Ordinary National and Provincial Highways
摘要
基于某地区2022-2025年普通国省道交通量数据、第一车道与第二车道路况评定数据及路线年报,采用描述性统计、Pearson相关分析、配对t检验和单因素方差分析(ANOVA),系统分析路况演变规律及交通荷载、路龄、车道位置的影响。结果表明:PQI年均值92.80,整体稳定;货车流量与PQI(r=-0.217)、RQI(r=-0.272)、RDI(r=-0.175)呈极显著负相关(p<0.001);路龄超过15年后PQI、PCI、RQI显著下降(ANOVA,p<0.001);第二车道(主要货运车道)PQI均值92.64,第一车道均值94.23,配对差值-1.59分(p<0.001)。货车荷载、路龄增长和车道位置是影响路况的关键因素。
Abstract
Based on traffic volume data, lane-specific pavement condition data (Lane 1 and Lane 2), and annual reports of ordinary national and provincial highways in a certain region from 2022 to 2025, descriptive statistics, Pearson correlation analysis, paired t-test, and one-way ANOVA were employed to systematically analyze the evolution of pavement condition and the impacts of traffic load, pavement age, and lane position. The results show that the annual mean PQI is 92.80, indicating stable overall performance. Truck volume is significantly negatively correlated with PQI (r=-0.217), RQI (r=-0.272), and RDI (r=-0.175) (p<0.001). After 15 years of service, PQI, PCI, and RQI decrease markedly (ANOVA, p<0.001). The mean PQI of Lane 2 (main freight lane) is 92.64, while that of Lane 1 is 94.23, with a paired difference of -1.59 (p<0.001). Truck load, pavement age, and lane position are key factors affecting pavement condition.关键词
