Abstract
Background:In Thailand, it has the second highest road traffic fatality rate in the world at 36.2 deaths per 100,000 populations. The pedestrian crash zones are based on the road and physical environment, vehicle and driver behavior and pedestrian behavior, especially the area around the school. Therefore, this paper would like to improve safety by identifying crash area through Geographic Information Systems (GIS).Objective:The objective of this paper is to identify pedestrian crash zones of primary schools and secondary schools in Bangkok, Thailand through the spatial analysis and GIS tool.Method:The research methodology was the data collection from pedestrian-vehicle crashes in 2016 at 12 schools of 1,218 locations in Bangkok. The data analysis used GIS for geocoding the crash locations. The spatial patterns and pedestrian crash zone map were applied by Moran’s I statistic and the Kernel Density Estimation (KDE).Results:The Moran’s index showed that the accident locations within school zone were a clustered pattern considering on Moran’s Index which approached +1 and the z-scores greater than 2.58. The KDE showed that the pedestrian crash zones were different depending on the physical environment; however, the most significant areas were at urban areas, crowded areas, and intersections of arterial roads and local roads about 508 meters from the school center.Conclusion:This research could be concluded that the spatial patterns and pedestrian crash zone map will assist the transportation planners and traffic police for identifying crash locations and specific vulnerable road users, especially pedestrians and bicycle users.
Highlights
In Thailand, it has the second highest road traffic fatality rate in the world, that estimating over 66 deaths every day from the analysis of The World Health Organization (WHO) [1]
In order to promote pedestrian activities in urban areas and to reduce the uses of personal cars which cause traffic congestion in Bangkok, the objective of this paper is to identify pedestrian crash zones of primary schools and secondary schools in Bangkok, Thailand through the spatial analysis and Geographic Information Systems (GIS) tool
According to the review of the related literature, schools are one of the accident black spots in Thailand. This is because a majority of road users is children who lack pedestrian experience which can highly lead to accidents [5 - 7]
Summary
In Thailand, it has the second highest road traffic fatality rate in the world, that estimating over 66 deaths every day from the analysis of The World Health Organization (WHO) [1]. When considering the death based on ages, the death rate among children below 15 years old is 4.53 deaths per 100,000. Accident prevention plans made by the government mainly aim to solve the overall accident problems It lacks analysis and specific prevention plans for children and vulnerable road users. This problem causes loss of life and affects the confidence in resolving road infrastructure. In Thailand, it has the second highest road traffic fatality rate in the world at 36.2 deaths per 100,000 populations. This paper would like to improve safety by identifying crash area through Geographic Information Systems (GIS)
