Abstract

The Dr. Wahidin intersection – Jalan Pramuka – Jl Bakso is one of several intersections in the city of Palu. The traffic on this road is quite busy and sometimes there are queues of vehicles due to vehicle encounters, which results in congestion, reducing the comfort level. This study aims to determine the performance of the Jl. Dr. Wahidin – Jl. Scouts – Jl. Meatballs in serving traffic flow in the present and in the future and knowing solutions in solving problems at unsignalized intersections Jl.Dr, Wahidin - Jl. Scouts – Jl. Meatball. Data collection was obtained based on primary and secondary data, primary data namely traffic volume, geometric intersections, and side barriers, secondary data in the form of maps of the city of Palu, population, and number of vehicle growth. From the results of research and discussion at the Dr Wahidin intersection - Jalan Pramuka - Jl Bakso, the total volume of traffic flow (Qtot) is 2337 pcu/hour, Capacity (C) is 4655.1 pcu/hour, Degree of Saturation (DS) is 0, 51, and queue odds (QP) 11-25%. Based on the results of the study, the performance of the Dr. Wahidin - Jalan Pramuka - Jl Bakso intersection has a stable flow level of service (C), but controlled vehicle speed and motion.

Abstract

Signalized intersections are critical components of urban traffic systems. However, inefficiencies caused by start-up lost time (SULT) and increased accident risks remain major challenges. Green Phase Warning Systems (GPWS) have emerged as an Intelligent Transportation System (ITS) innovation to reduce SULT and improve traffic safety. This paper presents a literature review of GPWS research published from 2010 to 2025. Findings show that GPWS reduces driver reaction time by 15–25%, increases intersection throughput up to 20%, and decreases rear-end collision risks. However, its effectiveness in heterogeneous traffic contexts, particularly in Indonesia where motorcycles dominate, remains limited. Future studies should focus on adaptive GPWS designs tailored for mixed traffic and explore policy frameworks supporting large-scale adoption.
