Analisis Kinerja Jaringan Jalan Kota Dumai Menggunakan Pendekatan PKJI 2023 dan Pemodelan PTV Visum 25

Urban development and the increasing number of vehicles in Dumai City have led to a growing demand for an effective and sustainable transportation system. This condition may reduce road network performance due to increasing traffic volume that is not balanced with adequate road capacity improvements. This study aims to evaluate road performance in Dumai City, analyze traffic movement distribution patterns, and determine appropriate improvement strategies for road segments experiencing performance degradation. The research method was conducted through road capacity and level of service analysis based on the Indonesian Highway Capacity Manual (PKJI) 2023 and transportation modeling using PTV Visum 25 on 14 selected road segments. The data used include traffic volume, road geometric characteristics, side friction conditions, and supporting network data. The results show that most road segments still maintain good performance under existing conditions; however, degradation occurs under the 10-year projection. Prof. M. Yamin Road is identified as the most critical segment with a degree of saturation of 0.89 (LoS E). The proposed widening from 8 to 9 meters increases capacity from 2823 to 3096 pcu/hour. The novelty of this study lies in the integrated application of PKJI 2023 and PTV Visum 25 to simultaneously evaluate road performance and traffic distribution under multi-period projections, providing a more comprehensive and forward-looking approach to urban transport planning
