Abstract |
KotaKinabalu is one of the major cities in Sabah which has traffic congestion due to abundance of private vehicle and slow improvement of traffic facilities. Traffic congestion is an urban mobility problem that worsens traffic flow and cause economic hindrance. Traffic volume and capacity are closely related to traffic congestion because once thevolumes exceed the capacity, the traffic congestion will occur. The scope of the study is a network from Indah Permai (IP) to Kota Kinabalu International Airport (KKIA).The objectives of this study are to find maximum flow, bottleneck and shortest path. Hence, capacity and distance of the routes within the scope were obtained from Dewan Bandaraya Kota Kinabalu (DBKK) and Google Map. Capacitated and weighted network graph were formed with all the obtained data. Next, Ford-Fulkerson algorithm, Max flow-Min cut theorem and Dijkstra’s algorithm were applied to solve the network graph. The maximum flow and the shortest path problem were formulated intoa linear programming(LP) model, and solved by using the excel solver in Microsoft Excel. From theresults, the traffic congestion problem was minimized and traffic flow became smooth.
