Highlights ► Seven critical areas in Santiago, Chile concentrate high child pedestrian risk rates during the period 2000–2008. ► Two of the identified critical areas belong to a lower middle socioeconomic level. ► The critical areas situated within the districts of Santiago and Estacion Central overlap with the high school density. ► There is a strong spatial and temporal dependence of child pedestrian crashes with respect the pedestrian responsibility.

    Abstract This paper presents a spatial and temporal analysis of child pedestrian crash data in Santiago, Chile during the period 2000–2008. First, this study identified seven critical areas with high child pedestrian crash risk employing kernel density estimation, and subsequently, statistically significant clusters of the main attributes associated to these crashes in each critical area were determined in a geographic information systems environment. Moran's I index test identified a positive spatial autocorrelation on crash contributing factors, time of day, straight road sections and intersections, and roads without traffic signs within the critical areas during the studied period, whereas a random spatial pattern was identified for crashes related to the age attribute. No statistical significance in the spatial relationship was obtained in child pedestrian crashes with respect to gender, weekday, and month of the year. The results from this research aid in determining the areas in which enhanced school-age child pedestrian safety is required by developing and implementing effective enforcement, educational, and engineering preventive measures.
