Abstract

The Purbalingga–Pemalang road has become a site of frequent traffic accidents due to its steep slopes, sharp curves, and lack of adequate road safety infrastructure. This study aims to assess the level of traffic accident risk using the HIRARC (Hazard Identification, Risk Assessment, and Risk Control) method, with the goal of identifying high-risk segments and dominant contributing factors. Primary data were collected through field inspections and hazard identification surveys, while secondary data were obtained from police accident reports over the past three years. Analysis focused on road conditions, safety facilities, and environmental factors. Results indicate that Segment 4 is the most hazardous, accounting for nearly 47% of accidents involving minor injuries and one fatality. Key risk factors include damaged pavement, poor visibility due to overgrown vegetation, lack of guardrails, and malfunctioning traffic signals. The risk assessment classified several segments as having moderate to high risk levels. These findings underline the urgent need for road surface repairs, improved traffic signage, vegetation management to enhance visibility, and stricter law enforcement. The study highlights the importance of integrating hazard-based risk assessment methods in transport planning and infrastructure maintenance. By addressing these critical issues, it is expected that traffic accidents on this road can be significantly reduced, thus improving overall road safety for all users.

Abstract

Understanding how pavement surface conditions influence operating speed is essential for improving road safety and optimizing urban traffic performance. This research investigates how pavement surface deterioration represented by the Surface Distress Index (SDI) influences vehicle operating speeds along Kolonel Sudiarto Street, a key urban roadway in Tegal City. A quantitative descriptive method was employed, in which pavement conditions were evaluated using the SDI framework, and vehicle speeds were obtained through space mean speed (SMS) measurements. A total of 358 vehicle samples were examined through simple linear regression to quantify the influence of SDI on motorcycle and passenger car operating speeds. The findings reveal a strong and statistically significant negative association between SDI and motorcycle speed (R² = 0.947), demonstrating that higher levels of pavement distress markedly decrease motorcycle operating speeds. In contrast, the relationship between SDI and car speed is weak and not statistically significant (R² = 0.064), suggesting that car speeds are influenced more by traffic dynamics and vehicle stability than by pavement surface deterioration. Combined regression simulations further demonstrate that motorcycles are markedly more sensitive to incremental surface distress. These findings affirm the relevance of SDI as a key indicator for evaluating pavement performance and predicting speed behavior, emphasizing the need for timely maintenance interventions to support safer and more efficient urban road operations.
