Improved Settlement Modeling of Leca Column–Raft Systems in Soft Clay: Influence of Friction Angle and Material Properties

Azhani Zukri, Dayang Zulaika Abang Hasbollah, Reza Pahlevi Munirwan

Stone columns are widely recognized as an effective ground improvement technique to enhance the bearing capacity of soft clay, reduce compressibility, and accelerate consolidation by providing drainage for excess pore water. Conventional columns are typically filled with coarse aggregates, but increasing attention …

STATISTICAL ANALYSIS OF RED-LIGHT VIOLATIONS ACROSS DIFFERENT TRAFFIC SIGNAL SYSTEMS AND OPERATING CONDITIONS

Othman Che Puan, Khairil Azman Masri, Intan Suhana Mohd Razelan, Azlina Hj. Ismail et autres

Red-light violations (RLVs) at signalised intersections continue to pose major safety challenges, especially where traffic flow characteristics vary across urban and suburban environments. This study examines how different traffic signal systems, traffic conditions, area types, and yellow-light durations influence RLV patterns at …
