Analysis of Traffic Accidents on Brigjen Sudiarto Road, Pedurungan District, Semarang City

Abstract Brigjen Sudiarto roads is a provincial road located in the Pedurungan sub-district, Semarang City, Central Java Province. This research uses this road because in the last 5 years from 2018 to 2022, there have been 230 accidents on this road with a total of 271 accident victims based on accident data from the West Semarang Police. The purpose of this study is to determine the characteristics of traffic accidents on Brigjen Sudiarto road during the 2018 – 2022 period, find out the locations of accident-prone points on Brigjen Sudiarto road, and provide advice as a prevention of traffic accidents in the future. This study describes the current conditions. This study uses the Accident Equivalence Rate (AEK) method and the Upper Control Limit (UCL) method. If the AEK value is greater than the UCL value, it means that the location is an area prone to traffic accidents. The results of the research are the characteristics of traffic accident data from 2018 – 2022 based on the highest per segment the highest is in segment 3 with a total of 105 incidents, and for all characteristics segment 3 is also the highest recorded. The highest accidents based on time (hour) occurred at 06.01-12.00 WIB with a total of 86 incidents, the highest accidents based on day occurred on Wednesday with a total number of 38 incidents, the highest accident based on victim class was minor injured victims (LR) with a total number of 200 incidents, the highest accidents based on gender were male victims with a total of 175 incidents, the highest accidents based on age occurred in victims aged (> 48 years) with a total of 71 incidents, and the highest accidents based on the type of vehicle were motorcycles with a total a total of 155 incidents. The results of the analysis of accidents on the Brigjen Sudiarto road which were carried out for five years (2018-2022) based on the Accident Equivalent Number (AEK) method and the Upper Control Limit (UCL) method occurred in segment 3 in 2018 with AEK = 114 and UCL = 82 Segment 1 in 2019 with AEK = 111 and UCL = 97. Segment 3 in 2021 with AEK = 117 and UCL = 93. Segment 3 in 2022 with AEK = 105 and UCL = 102. Meanwhile in 2020 the AEK value does not exceed the UCL value limit. This means 4 years of blackspot and 1 year of no blackspot during the last 5 years. The solution as a step to minimize accidents in segments 3 and 1 is to remake road markings, install traffic warning signs in accident-prone locations and repair damaged roads in accident-prone locations. This solution is expected to be implemented to reduce the occurrence of traffic accidents and casualties.
