Summary

This study conducts a Road Safety Audit (AKJ) of the Tangerang-Merak Toll Road in Indonesia to identify accident-prone areas and assess infrastructure deficiencies. The research is motivated by the high frequency of traffic accidents on this corridor, which connects Jakarta’s satellite city of Tangerang to the Merak Port. In 2018, the toll road recorded 913 accidents resulting in 386 victims, including 25 fatalities. While human error is cited as the primary cause of accidents in Indonesia, the authors argue that inadequate road infrastructure and missing safety facilities contribute significantly to "hazard surprises," necessitating a proactive audit to improve safety. The methodology combines direct field observations with statistical analysis of secondary accident data. Field surveys were conducted using GoPro cameras to record geometric conditions, pavement quality, and the presence of road furniture such as signs, markings, and medians. These observations were compared against technical standards. Simultaneously, the study analyzed 2018 accident data from the toll operator, PT Marga Mandalasakti. To identify black spots, the authors calculated the Equivalent Accident Number (EAN) for each road segment, weighting fatalities (12), serious injuries (6), minor injuries (3), and vehicle damage (1). These EAN values were then compared against statistical thresholds derived from the Upper Control Limit (UCL) and Upper Control Limit (BKA) methods to determine which segments exceeded safe accident rates. The findings reveal specific infrastructure flaws and high-risk zones. Field observations identified several segments with uneven or wavy pavement due to patching, particularly between Km 39.00–42.30 and Km 64.60–70.30. Crucially, the audit found missing warning signs for curves and speed limits at various locations, such as the right curve at Km 92.40–92.10 and left curves at Km 41.50–42.00, violating Ministerial Regulation No. 13 of 2014. Statistical analysis identified three segments as accident-prone "black areas": Balaraja Barat–Cikande, Cikande–Ciujung, and Ciujung–Serang Timur. The Cikande–Ciujung segment had the highest EAN score of 723, driven by 19 fatalities and 42 serious injuries, exceeding both UCL and BKA thresholds. The study concludes that while the toll road’s geometric design generally meets standards, deficiencies in pavement maintenance and the absence of critical warning signs create hazardous conditions. The correlation between poor pavement conditions and missing signage in high-accident segments suggests that infrastructure improvements could mitigate risk. The authors recommend more rigorous field surveys and better data collection tools for future audits. This research highlights the importance of integrating physical infrastructure audits with statistical accident analysis to proactively address safety hazards on high-traffic toll roads in developing nations.
