Abstract

The rapid growth of motorcycle vehicles coupled with inadequate traffic discipline contributes to an escalating rate of traffic accidents and casualties. This study investigates the efficacy of auxiliary road markings in enhancing traffic safety and intersection performance along Lieutenant Sutopo Street, Promoter Street, and Boulevard BSD East in South Tangerang, Indonesia. Employing the Traffic Conflict Technique (TCT), the research evaluates safety enhancements and service level alterations subsequent to the installation of road markings. Preliminary observations highlight significant safety concerns and traffic conflicts at the intersection. Consequently, auxiliary road markings are strategically installed to regulate driver behavior, enhance lane discipline, and improve visibility. Post-installation observations revealed a significant decrease in total vehicle conflicts, though the percentage of severe conflicts slightly increased. Initially rated as Level of Service (LOS) F with high delays, the LOS remained the same post-marking installation but with reduced delays. Further cycle time adjustments improved the LOS to E, indicating a substantial overall reduction in delays. The findings suggest that although auxiliary road markings effectively reduce traffic conflicts and improve intersection performance, additional measures are necessary to address the severity of these conflicts. The study offers valuable insights into the effectiveness of road safety interventions, supporting broader strategies for improving traffic management and safety in urban areas.

Bahasa Abstract

Pertumbuhan pesat kendaraan sepeda motor yang disertai dengan disiplin lalu lintas yang tidak memadai berkontribusi pada meningkatnya tingkat kecelakaan dan korban lalu lintas. Studi ini menyelidiki efektivitas marka jalan tambahan dalam meningkatkan keselamatan lalu lintas dan kinerja persimpangan di sepanjang Jalan Letnan Sutopo, Jalan Promoter, dan Boulevard BSD Timur di Tangerang Selatan, Indonesia. Menggunakan Teknik Konflik Lalu Lintas (TCT), penelitian ini mengevaluasi peningkatan keselamatan dan perubahan tingkat pelayanan setelah pemasangan marka jalan. Pengamatan awal menyoroti kekhawatiran besar terkait keselamatan dan konflik lalu lintas di persimpangan. Oleh karena itu, marka jalan tambahan dipasang secara strategis untuk mengatur perilaku pengemudi, meningkatkan disiplin jalur, dan meningkatkan visibilitas. Pengamatan setelah pemasangan mengungkapkan penurunan signifikan dalam total konflik kendaraan, meskipun persentase konflik berat sedikit meningkat. Awalnya dinilai sebagai Tingkat Pelayanan (LOS) F dengan penundaan tinggi, LOS tetap sama setelah pemasangan marka tetapi dengan penurunan penundaan. Penyesuaian waktu siklus lebih lanjut meningkatkan LOS menjadi E, menunjukkan pengurangan penundaan secara keseluruhan yang substansial. Temuan ini menunjukkan bahwa meskipun marka jalan tambahan efektif mengurangi konflik lalu lintas dan meningkatkan kinerja persimpangan, tindakan tambahan diperlukan untuk mengatasi tingkat keparahan konflik tersebut. Studi ini menawarkan wawasan berharga tentang efektivitas intervensi keselamatan jalan, mendukung strategi yang lebih luas untuk meningkatkan manajemen lalu lintas dan keselamatan di daerah perkotaan.
