Road Performance and Traffic Density Assessment on Urban Road Segments in Maros

Abstract

This study analyzes traffic performance and congestion on urban road sections in Maros Regency. The assessment applies the 2023 Indonesian Road Capacity Guidelines (PKJI) and covers road capacity, free-flow speed (Vb), and road user perceptions of congestion. Traffic performance indicators, namely Degree of Saturation (DS) and Speed Performance Index (SPI), were derived from field observations and a user survey. Results indicate a free-flow speed of 47.3 km/h and an effective capacity of 2,674 pcu/h on the observed segment. Congestion patterns are directional and time-dependent. The Maros to Makassar direction is busiest in the morning, while the Makassar to Maros direction reaches its peak in the late afternoon, with DS values at or above 0.85. The highest DS reaches 0.91, while the lowest SPI is 16, indicating severe congestion conditions. Survey responses corroborate these peak periods, aligning perceived congestion with empirical indicators. The findings provide evidence for operational controls and targeted geometric improvements to enhance traffic flow and reliability on this corridor.
