Determining the road traffic accident hotspots using GIS-based temporal-spatial statistical analytic techniques in Hanoi, Vietnam

Abstract: This study applied GIS-based statistical analytic techniques to investigate the influence of accident Severity Index (SI) on temporal-spatial patterns of accident hotspots related to the specific time intervals of day and seasons. Road Traffic Accident (RTA) data in 3 years (2015 − 2017) in Hanoi, Vietnam were used to analyze and test this approach. Firstly, the RTA data were divided into four seasons in accordance with Hanoi's weather conditions and the time intervals such as the daytime, nighttime, or peak … Show more

“…Le K G et al in their study were able to establish a relationship between the frequency of accidents and their time of occurrence and as per their study, the frequency was higher between 2:00 pm and 3:00 pm and also between 7:00 pm and 11:00 pm. [ 16 ] This might be attributed to increase in the activities on the road during evening hours. Moreover, it is speculated that people have reduced efficiency and focus towards the end of the day.…”

“…GIS was used by Le KG et al at Hanoi, the area of study in Vietnam, and here hotspots were noted in the center of Hanoi, which has many cross roads and also along the National Highway (NH)-1A. [ 16 ] Achu AL et al conducted a similar study in Thrissur, Kerala using a tool that identifies spatial clusters or hot spots and found clustering of accidents in Thrissur town. [ 17 ]…”

“…Weights, which are proportional to the distance from the point event, are assigned to the surrounding area by the kernel function. (13) If the distance attenuation is large, the area of the hot spot will be large. This is more obvious on a global scale, but it is not easy to reflect the details of the area of the hot spot.…”

“…The road transportation system presents a high-risk system that threatens people’s lives every day [ 1 ]. The severity of traffic accidents raises many social direct and indirect problems, physical and mental health disorders, economic expenses, and massive damage to the surroundings and properties [ 2 ].…”
