Prediksi Lalu Lintas Terhadap Lalu Lintas Terhadap Rencana Pembangunan Dumai Eco Park

Dumai City has growing tourism potential, especially with the constructing of 30-hectare Dumai Ecopark. This development is expected to increase the traffic volume around the area, especially in Dumai-Pelintung and Mattaim Street. Therefore, a Traffic Impact Analysis (TIA) was required to anticipate changes in traffic patterns and maintain smooth transportation. A primary survey was conducted to obtain average daily traffic (ADT) data and vehicle speed using the manual enumeration method. The analysis results show that in the existing condition, the traffic flow is still in a stable category based on the degree of saturation (Dj) value. However, in the next 5 to 10 years projection, especially after the development of Dumai Ecopark, the Dj value on the Dumai-Pelintung street section and the entrance intersection increases significantly, approaching the Degree of Saturation (Dj ≥ 0.85). Therefore, traffic management recommendations are needed, such as the implementation of a one-way system on Penghulu Hamzah Street and the addition of left-turn lanes at the entrance junction, in order to maintain smooth traffic flow and support the economic growth of Dumai City.
