【摘要】:為了探究土地利用對(duì)交通安全的影響,基于交通事故、交通小區(qū)邊界、路網(wǎng)、交通流量、人口以及建筑物用地?cái)?shù)據(jù),以交通小區(qū)為分析單元,將用地特征參數(shù)作為聚類指標(biāo),利用K均值聚類算法將土地利用劃分為5類用地組合形態(tài),采用半?yún)?shù)地理加權(quán)回歸和方差分析的方法研究用地組合形態(tài)對(duì)交通安全的影響.結(jié)果表明,自然生態(tài)型用地形態(tài)的事故風(fēng)險(xiǎn)是居住用途主導(dǎo)的用地形態(tài)的1.171倍,社區(qū)服務(wù)型用地形態(tài)的事故風(fēng)險(xiǎn)是居住用途主導(dǎo)的用地形態(tài)的0.641倍,不同的用地組合形態(tài)之間社會(huì)經(jīng)濟(jì)和交通運(yùn)行特征差異顯著.用地組合形態(tài)通過(guò)社會(huì)經(jīng)濟(jì)和交通運(yùn)行間接地影響交通安全,其中自然生態(tài)型的用地形態(tài)最安全,社區(qū)服務(wù)型用地形態(tài)最危險(xiǎn),是交通安全管理的重點(diǎn).
[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.
