摘要:
为了探究土地利用对交通安全的影响,基于交通事故、交通小区边界、路网、交通流量、人口以及建筑物用地数据,以交通小区为分析单元,将用地特征参数作为聚类指标,利用K均值聚类算法将土地利用划分为5类用地组合形态,采用半参数地理加权回归和方差分析的方法研究用地组合形态对交通安全的影响.结果表明,自然生态型用地形态的事故风险是居住用途主导的用地形态的1.171倍,社区服务型用地形态的事故风险是居住用途主导的用地形态的0.641倍,不同的用地组合形态之间社会经济和交通运行特征差异显著.用地组合形态通过社会经济和交通运行间接地影响交通安全,其中自然生态型的用地形态最安全,社区服务型用地形态最危险,是交通安全管理的重点.
Abstract:
To investigate the influence of land use on the traffic safety, by taking the traffic districts as the analysis unit and the land-use characteristic parameters as the clustering index, five land-use combinations were divided by using the K-means clustering algorithm based on crash, traffic analysis zone boundary, road network, traffic flow, population and land-use data. The influence of the land-use combinations on traffic safety was studied by the methods of semi-parametric weighted Poisson regression and variance analysis. The results show that the crash risks of ecotype and community service land-use are 1.171 and 0.641 times that of residential land-use, respectively. The social-demographic and traffic parameters of different land-use combinations are significantly different. The land-use combinations indirectly affect the traffic safety through social-demographic and traffic operation. The ecotype land-use combination is the safest, and the land-use combination of community service is the most dangerous which deserves more attention in traffic safety treatment.
