Abstract
Technological developments in transportation planning provide consultants with great opportunities to improve the accuracy and efficiency of traffic analysis. One important tool is VISSIM software, which allows realistic simulation of traffic dynamics. However, its utilization has not been optimal among consultants, including PT HAGEN AMERSA VETA, due to limited knowledge. This community service aims to raise the competence of PT HAGEN AMERSA VETA staff through VISSIM training. The method uses blended learning, combining theory, case studies, and hands-on practice. The evaluation was conducted through pretest and post-test. The pretest results showed an average score of 56.18, reflecting limited basic understanding. After the training, the post-test score increased significantly to 84.79, demonstrating an understanding of the concept to practical application of VISSIM. The training proved to significantly improve consultant competency, benefiting participants while improving the quality of the company's services in transportation projects.

Salah satu alat penting adalah software VISSIM, yang memungkinkan simulasi dinamika lalu lintas secara realistis. Namun, pemanfaatannya belum optimal di kalangan konsultan, termasuk PT HAGEN AMERSA VETA, karena keterbatasan pengetahuan. Pengabdian masyarakat ini bertujuan meningkatkan kompetensi staf PT HAGEN AMERSA VETA melalui pelatihan VISSIM. Metodenya menggunakan blended learning, menggabungkan teori, studi kasus, dan praktik langsung. Evaluasi dilakukan melalui pretest dan post-test. Hasil pretest menunjukkan rata-rata skor 56,18, mencerminkan pemahaman dasar yang terbatas. Setelah pelatihan, skor post-test meningkat signifikan menjadi 84,79, menunjukkan pemahaman konsep hingga aplikasi praktis VISSIM. Pelatihan ini terbukti meningkatkan kompetensi konsultan secara signifikan, memberikan manfaat bagi peserta sekaligus meningkatkan kualitas layanan perusahaan dalam proyek transportasi.
