The Punge intersection in Banda Aceh City is a four-armed intersection without traffic control devices such as traffic lights and roundabouts. The intersection performance from visual observation is currently very low, especially during peak hours. Therefore, it is presently considered necessary to evaluate road performance and carry out alternative handling planning. One alternative handling is to plan a roundabout at the intersection. Thus, this study aims to obtain road performance by comparing the use of a roundabout and without a roundabout. Analysis and planning using the MKJI and PTV Vissim 10.00-02 methods. It requires data on traffic volume, road geometry, and environmental conditions around the location. The analysis of roundabout planning with the widening of each arm with the MKJI and Vissim methods produces the level of services to deliver the best decisions for improving the intersection performance
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
