摘要

作为道路安全管理的一个组成部分,提出了一种方法来识别和确定具有风险部门的群体,因为城市地区交通事故的发生率更高。该方法基于探索性数据分析(AED)、核密度估计(KDE)以及相关和地质处理技术的应用,在空间分析和地理统计中构建。2015年至2018年间从​​哥伦比亚博亚卡的通贾是研究事件分布、集群特征、发生动力学和模式建模的基础。风险的定义和定界取决于加权核发现的分散或分组(热点),以及由于该部门的领土动态而导致的潜在过程的社会空间相互关系。结果揭示了具有不同风险水平的集中区的事件模式,其中根据其活动[商业和住宅],具有相反特征的土地利用共存,低阶层的社会经济部门与混合的主干道网络共存,其功能调动了高车流量和人流量。尽管分析仅限于案例研究,但通过区域变量的发生率来划分交通事故的风险点,研究结果显示了道路安全的前景。

Spatial Analysis with Weighted Kernel Groupings to Determine Risk Sectors Due to Traffic Accidents in Urban Area. Tunja Analysis, Colombia
A method is presented to identify and determine groups with risk sectors due to the greater occurrence of traffic accidents in urban areas as an integral component in road safety management. The methodology was framed in Spatial Analysis with geographic statistics based on Exploratory Data Analysis (AED), Kernel Density Estimation (KDE), and the application of correlation and geoprocessing techniques. The accident data collected between 2015 and 2018 from the urban area of ​​Tunja, Boyacá, Colombia, were the basis for the study of the distribution of events, characterization of clusters, occurrence dynamics and pattern modeling. The definition and delimitation of risks depended on the dispersion or grouping (Hotspots) found with weighted Kernel together with the socio-spatial interrelation of underlying processes due to the territorial dynamics of the sector. The results reveal patterns of events in concentration foci with different levels of risk, in which land uses of opposite characteristics coexist according to their activities [commercial and residential], socioeconomic sectors of low strata with a mixture of arterial road network that by its functionality mobilizes high vehicular and pedestrian flows. Although the analysis is limited to a case study, the findings show a promising perspective in road safety by delimiting risk sites for traffic accidents through the incidence of territorial variables.

期刊介绍: Cuadernos Geográficos es una revista científica que se edita desde 1971 bajo el patrocinio de los Departamentos de Geografía de la Universidad de Granada. Acepta textos inéditos de investigación relativa a las relaciones entre la sociedad y el territorio, que contribuyan al desarrollo de la Ciencia Geográfica, en cualquiera de sus áreas de conocimiento, así como crónicas, notas y reseñas bibliográficas relativas a la actividad geográfica en cualquier parte del mundo, aunque especialmente en España y Andalucía, Latinoamérica y los países mediterráneos.
