Analisis Level of Service (LOS) Dalam Mengantisipasi Kemacetan Lalu Lintas Di Ruas Jalan Raya Soreang-Kopo Kabupaten Bandung

The Soreang-Kopo Highway section in the Bandung Regency area is an arterial road that connects Bandung City with Ciwidey via Soreang. Apart from that, the Soreang-Pasirkoja toll road is also connected to this road network, making it easier to access various areas in West Java. This road section is a road section that is very congested with traffic and is crossed by various types of vehicles, including heavy vehicles, with quite high intensity. The aim of this research is to provide an overview of capacity (C) and traffic flow (Q) as an illustration of the road's performance which provides the level of service and to analyze the traffic characteristics on the Jalan Raya Soreang-Kopo section. The research was conducted using primary data and secondary data. Primary data is obtained from observations, traffic counters, and documentation of data.
