Analysis of unsignalized intersection upgrading at constrained area in the city of Banda Aceh

Abstract

The city of Banda Aceh is the capital city of Aceh province. The city's population is 259,913, and the city's annual population growth rate is 1.97% (BPS, 2018). Punge intersection is one of the intersections in Banda Aceh; this intersection is passed by the numerous and dense traffic. Based on the observation in certain hours at Punge intersection, it reveals several problems, namely: the intersection capacity and the performance level of the intersection. As a result, this study is aimed to evaluate the performance of Punge intersection. The intersection calculation was based on the Indonesia Highway Capacity Manual (MKJI, 1997). The benefit that can be obtained from this research is to eliminate traffic conflict. According to the survey, it was discovered that the dominant traffic (3,053 pcu/hours) was at the Sultan Iskandar Muda Street, D, from the central city to Ulee Lheu; on the contrary, only a few traffic (559 pcu/hours) passed on Cempaka Punge Jurong Street, A. By way of conclusion, the intersection capacity is inadequate because the degree of saturation has exceeded 0.85, viz 1.851. Therefore, Simpang Punge needs some improvements, such as repairing traffic lights and its geometric.
