Abstract

Geometric planning of Toll Roads for Section IIIA Bogor Ring Road. Bogor City and Bogor District are part of the Jakarta, Depok, Tangerang and Bekasi regions which have become a buffer for the Indonesian capital city, Jakarta. This resulted in very rapid regional growth. Bogor City and Bogor District are functioned as development areas that will be able to accommodate various types of activities such as housing, industry, agriculture, tourism and others. The problem of traffic in the city of Bogor, especially at this time is the traffic congestion at several nodes prone to traffic jams caused by delays in traffic flow. One alternative that is expected to provide a solution is to build the Bogor Ring Road Toll Road. The construction of the Bogor Ring Road Toll Road is divided into 3 sections; section I of segment Sentul Selatan-Kedung Halang, section II is divided into IIA; section IIA of segment Kedung Halang-Kedung Badak, section IIB of segment Kedung Badak-Simpang Yasmin segment are already in operation and section IIIA of the segment Yasmin Simpang-Salabenda intersection segment are in the planning stage. In the geometric planning of toll roads, horizontal alignment is calculated so that the horizontal alignment curve type is obtained and the horizontal alignment arch length is in accordance with the road geomertic standard. From the calculation results obtained 4 types of horizontal alignment arches and the length of horizontal alignment arches; the first horizontal alignment arc-circle-spiral length 707,831m, the second full-circle horizontal alignment arc length 264,913m, third the horizontal full-circle alignment arc length 311.01m, the fourth horizontal-arc-circle-spiral alignment arc length 464,985m.
