Level of Service (L.O.S) Analysis: A Case Study in Jalan Drs. Esau Sesa, Manokwari District, West Papua Province

Abstract


 Jalan Drs. Esau Sesa is a non-shared two-way connecting road owned by the Manokwari Regency Government, Papua Barat Province. This road is the main road that connects between districts with a road width of + 6 meters. The rapid development of land use along with Drs. Esau Sesa has the potential to reduce road service levels. Field observations showed that commercial activities are high in this area. Thus the traffic activities, as well as parked vehicles are also high, exceeding the facilities capacities. This condition is one of the causes of traffic jams on the road. Based on the data analysis results, Jalan Drs. Esau Sesa has a Road Capacity (C) of 2,061 vehicles/hour with a Free Flow Velocity (FV) of 45,315 Km/hour and a Degree of Saturation (DS) of 0.808. These results are equivalent to the Level of Service (L.O.S) at level D which means traffic flow on Jalan Dr. Esau Sesa began to become unstable, with low traffic jams with creeping currents and vehicle volumes approaching maximum capacity.

Road widening in west Papua: A design and economic feasibility analysis of urban green infrastructure

“…Esau Sesa -Maruni. According to research in 2021 [1], the road capacity (C) is 2,061 vehicles/hour, the average volume of traffic (Q) is 1,666 vehicles/hour, the degree of road saturation (DS=Q/C) is 0.81, and it is classified as service level D. That is, Jalan Dr. Esau Sesa -Maruni began to become unstable, there was a minor traffic bottleneck with slightly unsafe behavior, and the number of cars was approaching maximum capacity. However, the most recent data show that the current Q value has reached 2,528 vehicles/hour, with a DS value of 1.23 [2], placing it in the F category, which includes limited traffic flow, low speed, volume below capacity, and frequent stops.…”
