RESUMEN
RESUMEN Objetivo. Identificar las áreas de mayor concentración de accidentes de tránsito y lesionados en el Área Metropolitana de San Salvador (AMSS). Materiales y métodos. Los accidentes de tránsito se analizaron espacialmente mediante la ubicación puntual y por la sumatoria de eventos en áreas de 200 m2. La ubicación puntual se analizó mediante «análisis de vecinos más cercanos¼, mientras que las áreas con la sumatoria de accidentes de tránsito se analizaron mediante Gi* de Getis-Ord para obtener los puntos calientes. Los puntos calientes resultantes con mayor concentración de accidentes de tránsito en el AMSS se evaluaron en campo mediante un formulario de observación de las características de infraestructura y seguridad vial. Resultados. Al analizar 8191 accidentes de tránsito reportados entre 2014‒2018, se identificaron cinco áreas con mayor cantidad de accidentes de tránsito y lesionados, principalmente sobre vías primarias. Conclusión. Los sitios de mayor concentración de accidentes de tránsito y lesionados se caracterizan por una infraestructura vial con daños considerables y falta de sistemas de seguridad para conductores y peatones. El análisis espacial de los accidentes de tránsito y lesionados puede contribuir a mejorar la vigilancia y seguridad vial en el AMSS.
ABSTRACT
ABSTRACT Objective. This study aimed to identify the areas with the highest concentration of traffic accidents and injuries in the San Salvador Metropolitan Area (SSMA). Materials and methods. Traffic accidents were analyzed spatially by point location and by the sum of events in areas of 200 m2. The point location was analyzed by "nearest neighbor analysis", while the areas with the sum of traffic accidents were analyzed by Getis-Ord Gi* to obtain the hot spots. The resulting hot spots with the highest concentration of traffic accidents in the SSMA were evaluated in the field using an observation form to collect data on infrastructure and road safety characteristics. Results. Five areas with the highest number of traffic accidents and injuries, mainly containing primary roads, were identified by analyzing 8191 traffic accidents reported between 2014-2018. Conclusion. The sites with the highest concentration of traffic accidents and injuries were characterized by considerably damaged road infrastructure and the lack of safety systems for drivers and pedestrians. The spatial analysis of traffic accidents and injuries can contribute to improve surveillance and road safety in the SSMA.
