Analisis Sistem Jaringan Transportasi di Kampus UGM

ABSTRAK Gadjah Mada University is situated in the urban agglomeration of Yogyakarta, and the campus is divided by a main busy road, i.e. Kaliurang Street. The university has, therefore, a great problem in traffic management. The aim of this research is to identify the traffic problems, including the road performance, traffic characteristics, public transport, parking, and also the internal policies to manage the traffic flow by the gate system UGM area. Surveys were carried out within the campus, such as geometric, traffic, and parking surveys. Interview surveys were also carried out to know the aspiration of road users. The results indicate that there are some junctions and roundabout in UGM that should be improved, such as geometric improvement. The result of the transport modelling analysis slums that the gate system has a big impact in main road traffic, i.e. Kaliurang Street. The result of simulating and analysing of the scenario shows that opening the gate in Puma Budaya Intersection could divert the traffic into Pancasila Street (UGM Boulevard) and also decrease the degree of saturation at Mirota Intersection. This scenario has also positive impact to minimise traffic conflict at intersection. This conclusion is also supported by interview survey, which shows that 66% of road users are agree to close the gate but only during the off peak periods (in the evening and at night), 22,5% of them are disagree to close, and 11,5% of them are agree to close permanently. The interview of public bus users and non-users shows that the students of UGM, who use buses are about 42%. The main reason of using buses is cheap (62%). The users claim that bus service is less and very less (71%). The non-users claim that buses have disturbed them (91%). The parking interview survey shows that the largest mode is motorcycles. According to the users, the main parking problem is the insufficient space for parking. The standard of parking area could be estimated by following equation: Y = 179,152 + 7,698 x 10 X i , ,R2 = 0,976 , where Y = parking space unit, and XI = the number of lecturers, employees and students.
