Abstract

Road curves often become vulnerable to traffic accidents, which remain a significant worldwide issue. This study provides an essential analysis of the effects of road geometry on curves on user safety. The main objective of this research is to identify the relationship between the features of curve infrastructure, such as radius, superelevation, and lane width, and the traffic accident rate. Accident data from various road segments in Indonesia was thoroughly analyzed. Special emphasis is placed on the types of accidents, their severity levels, and the contributing factors to these accidents. Studies show that curves with suboptimal designs, such as small radii or lack of superelevation, significantly increase the risk of accidents. Additionally, the consistency of geometric design and the visual perception of curves significantly affect the safety of drivers and other road users. This study highlights the importance of using a comprehensive approach in the planning and designing road curves to enhance overall transportation safety. The proposed recommendations include stricter design guidelines, improved maintenance, and better instructions for road users to reduce the risk of curve accidents.

Abstract

Middle Citys play a crucial role in the socio-economic landscape of developing cities, yet their integration with efficient public transportation systems remains a persistent urban challenge. This study presents a systematic literature review of research published between 2020 and 2025, aiming to evaluate the service levels of public transportation in Middle City environments. Using Publish or Perish and VOSviewer, 120 relevant studies were identified and analyzed across five key service dimensions: frequency, affordability, accessibility, safety, and user satisfaction. The findings reveal that while public transportation around Middle Citys is generally available, significant gaps remain in terms of affordability, safety, and inclusive access for vulnerable groups such as elderly users and informal workers. Geographic analysis shows that most research originates from rapidly urbanizing countries in Asia and Africa, highlighting regional concerns with informal commercial zones. This review underscores the urgent need for context-sensitive, participatory, and equity-focused planning approaches to improve public transport service quality in Middle Citys and similar urban environments..
