【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]:In order to investigate the impact of land use on traffic safety, based on traffic accident, traffic area boundary, road network, traffic flow, population and building land use data, the characteristic parameters of land use are taken as cluster index. Land use is divided into five types by K-means clustering algorithm. The effect of land use combination on traffic safety is studied by means of semi-parametric geo-weighted regression and variance analysis. The results showed that the accident risk of natural ecotype land use was 1.171 times that of residential land use, and the accident risk of community service land use was 0.641 times that of residential land use. There are significant differences in social economy and traffic operation between different land use combinations. The combination form of land use indirectly affects traffic safety through social economy and traffic operation, in which the natural ecotype is the safest and the community service is the most dangerous, which is the key point of traffic safety management.
