Abstract

Volunteer Traffic Controllers (Supeltas) in Pekanbaru City, particularly at the Soekarno Hatta U-turn in front of Jasmine Residence Shophouse, serve as a solution to the shortage of traffic officers. Their presence aids in regulating vehicle flow; however, community opinions are mixed. Some individuals appreciate the assistance provided by Supeltas, as they help reduce confusion for motorists, while others believe they contribute to slower traffic, especially during peak vehicle volume, thereby exacerbating congestion. This study aims to assess the impact of Supeltas on congestion around the Soekarno Hatta U-turn. The methodology employed is descriptive-qualitative analysis, alongside road performance analysis that encompasses variables such as road geometry, vehicle volume, vehicle speed, and delay time. The analysis results indicate that the presence of Supeltas increases the volume of vehicles at the U-turn but also decreases vehicle speed from 42 km/h to 37 km/h when Supeltas are present. Additionally, it causes an increase in the degree of saturation from 0.36 (without Supeltas) to 0.49 (with Supeltas). Nevertheless, the additional delay time incurred is relatively minor, amounting to only 1.27 seconds. Overall, the presence of Supeltas at the U-turn on Jl. Soekarno Hatta has a negative impact on traffic flow, both from an analytical perspective and from the viewpoint of the community, as their presence actually contributes to increased congestion. Implementing a one-way system at the U-turn could enhance its performance, or the addition of dedicated lanes at the U-turn in accordance with the Pedoman Perencanaan Putaran Balik (PPPB) 2005 could help reduce congestion.
