Abstract
This study aims to optimize vehicle speed predictions on toll roads using
the Cell Transmission Model (CTM). Given the challenges posed by dynamic
traffic conditions, particularly during peak hours, the research focuses on
calibrating the CTM's parameters to enhance prediction accuracy. Simulations
conducted on the Tangerang-Jakarta toll road demonstrated a significant reduction
in the Mean Absolute Percentage Error (MAPE), from 43.7% to 37.0%. The
findings highlight the critical role of parameter optimization in improving the
model’s reliability. Furthermore, the study investigates the impact of modifying
road topology, such as expanding lanes and adding additional off-ramps, on traffic
behavior. While these changes had a modest effect on prediction accuracy, they
provided valuable insights into the practical application of traffic modeling.
Ultimately, the research contributes to the theoretical advancement of traffic
modeling and offers practical recommendations for effective toll road
management and congestion mitigation. Future research is encouraged to
incorporate additional traffic variables and compare the CTM with other traffic
models to further enhance predictive capabilities./Penelitian ini bertujuan untuk mengoptimalkan prediksi kecepatan
kendaraan pada jalan tol menggunakan model Cell Transmission Model (CTM).
Mengingat tantangan yang ditimbulkan oleh kondisi lalu lintas dinamis, terutama
selama jam sibuk, penelitian ini fokus pada kalibrasi parameter-parameter CTM
untuk meningkatkan akurasi prediksi. Simulasi yang dilakukan pada jalan tol
Tangerang-Jakarta menunjukkan pengurangan signifikan pada Mean Absolute
Percentage Error (MAPE), dari 43,7% menjadi 37,0%. Temuan ini menyoroti
peran krusial dari optimisasi parameter dalam meningkatkan keandalan model.
Selain itu, penelitian ini juga menyelidiki dampak perubahan topologi jalan,
seperti penambahan jalur dan ramp tambahan, terhadap perilaku lalu lintas.
Meskipun perubahan tersebut hanya memberikan dampak yang moderat terhadap
akurasi prediksi, mereka memberikan wawasan berharga terkait aplikasi praktis
pemodelan lalu lintas. Secara keseluruhan, penelitian ini berkontribusi pada
pengembangan teori pemodelan lalu lintas dan memberikan rekomendasi praktis
untuk manajemen jalan tol yang efektif serta mitigasi kemacetan. Penelitian di
masa depan disarankan untuk menggabungkan variabel lalu lintas tambahan dan
membandingkan CTM dengan model lalu lintas lainnya guna lebih meningkatkan
kemampuan prediksi .
