Analysis of Traffic Accident Using the Accident Equivalent Number (EAN) Method and Upper Control Limits on Serang Road Km 23 – Km 35 Tangerang Regency

Abstract

Serang Road which is classified as a national road has a fairly high accident risk. Based on data from the Tangerang District Police for 2018-2022, it was found that the black site area is located at KM 23 – KM 35. It is necessary to identify the causes of the high number of accidents and solutions to reduce the number of accidents in that area. This study uses the Equivalent Accident Number (EAN) method, Upper Control Limit (UCL). The black site area from KM 23 – KM 35 with a total road length of 12 KM is divided into 12 observation Segments. Furthermore, sections identified as blackspots will be analyzed for road performance by referring to the 1997 Indonesian Road Capacity Manual (MKJI) and Guidelines for Handling Accident-Prone Locations (Pd-T-09-2004-B). The results of this study show that Segment 12 which is at KM 34 – KM 35 is a blackspot with the highest EAN value of 450 and exceeds the Upper Control Limit (UCL) value of 247,513 and the Upper Control Limit (BKA) of 252,187. If seen from the existing conditions in this Segment, with the 4/2UD road type located in industrial and commercial areas on both sides of the road, the service level is A (DS = 0.25) and the actual average speed is 50 km/hour, then this Segment potential for an accident. Especially in the time range 18.00-00.00 with the highest cause is a violation of the speed limit and is supported by the lack of lighting at night.
