On-Street and Off-Street Parking Analysis of Passenger Car in Malioboro, Yogyakarta

2023-12-06T14:43:12+00:00

The increasing number of commercial activities in the Malioboro area, Yogyakarta will have an impact on the increasing traffic
volume and parking space requirements. Therefore, this study aims to analyze the supply and demand of either on-street and off-street parking for passenger cars. To do so this study utilized quantitative method to evaluate the parking supply and demand. The analysis of parking supply considered the capacity for off-street parking at Malioboro Mall and on-street parking on Perwakilan Street, Yogyakarta. While parking demands are analyzed by considering Malioboro Mall floor area, number of visitors, and number of passenger cars parking at Malioboro Mall and Perwakilan street. The primary data was collected by conducting survey on-street and off-street parking of passenger cars, whereas secondary data was obtained from Transportation Office and Statistics Agency of Yogyakarta. The survey was conducted on the peak day (Saturday), at 10.00 AM to 20.00 PM by counting the passenger cars entering and exiting the parking areas. The result of analysis showed the maximum on-street parking accumulation (Ap) was 55 cars and off-street parking as many as 123 cars with parking volume (Vp) for on-street were 183 cars and off-street 421 cars. In addition, parking index (Ip) for on-street was 1.00 and off-street 1.171. Furthermore, the parking capacity (supply) consisted of on-street parking at Perwakilan Street was 55 cars and off-street parking at Malioboro Mall was 105 cars. The maximum on-street parking demand was 55 passenger cars, whereas off-street parking demand in Malioboro Mall
were estimated by three conditions, where the first parking demand (Dmax1), the second (Dmax2) and the third one (Dmax3) were 160, 146, and 176 passenger cars respectively. Generally, it can be concluded that the parking demand exceeds the parking capacity (supply), so additional parking space for the passenger car is required.

Performance Study of Three Parallel Runways at Soekarno-Hatta Airport

2023-12-06T15:13:02+00:00

To improve service quality, Soekarno-Hatta international airport is adding a runway, so that the runway becomes a three-parallel
runway. The runway is targeted to be able to accommodate the number of aircraft movements until 2020. This final assignment tries to find out whether the capacity of the planned runway can meet the targets that have been set. In this final project, we will review the distribution pattern of aircraft categories and the distribution of aircraft departure/arrival movements that affect the runway, then a simulation of aircraft movements will be carried out to obtain capacity on the runway. From the final assignment, the percentage distribution results of the aircraft categories used were C: 45% and D: 55%. The distribution of aircraft movements for runway 1 is departure: 59% and arrival: 41%, for runway 2 it is departure: 32.5% and arrival: 67.5% while for runway 3 it is departure: 40% and arrival: 60%. The results of the simulation of movements at peak hour were 124 movements. It is known from the data that peak hour aircraft movements in 2020 were 148 movements. With the results obtained, it was concluded that the aircraft movement target could not be met by adding the runway to a three-parallel runway.

Air Side Facilities Planning for Terminal 3 Juanda Airport, Surabaya

2023-12-06T15:15:50+00:00

Juanda Airport experiences a very rapid increase in the number of passengers from year to year, this has an impact on the
increase in aircraft movements which causes delays. To overcome this problem PT. Angkasa Pura I will develop Juanda airport by building Terminal 3 which is targeted to serve up to 75 million passengers. However, the construction of Terminal 3 needs to be equipped with detailed planning of airside facilities which include runway, exit taxiway, taxiway, and apron. This detailed planning will consider aircraft movements when the airport is fully operational to avoid delays. In planning the airside facilities at Terminal 3, air traffic movement data was collected from 2009 to 2016 to predict the planned target number of passengers. From the results of the analysis carried out, the number of passengers reaching this target occurred in 2031 with the number of aircraft movements per year being 414,727. The aircraft planned for this plan is the Boeing 737 Max 8 aircraft which is a new generation of Boeing 737-800 type aircraft, which is the aircraft with the maximum movement results in 2031. And aircraft movements during peak hours in 2031 will reach 61 movements/hour. This number of movements is obtained from a simulation of aircraft movements in the planning year. After calculating the runway capacity, it was found that 2 runways were needed to serve aircraft movements at Terminal 3 Juanda. The maximum runway capacity that can be generated with the composition of aircraft classes operating in Juanda is class B: 10%, C: 20%, and D: 70%. In planning this airside facility, it is also calculated that it can serve large
aircraft such as the A380. So, the runway length is 3900 m with a runway width of 86 m including the runway shoulder. The dimensions of the taxiway are 30 m including a shoulder width of 15 m on each side. The location of the exit taxiway along 2770 is measured from both ends of the runway at an angle of 300, and the area of the apron with pier (finger) type is 1,000,000 m2.

Analysis of the Effect of Vehicle Composition at Signalized Intersections on the Initial Loss Time of the Green Phase

2023-12-06T15:19:15+00:00

Cycle time consists of green time, yellow time, and red time. The green time of a phase is a function of the effective green time
as well as the initial loss time and final gain time. There needs to be an approach to determine the value of the initial loss time at signalized intersections. There are several aspects that influence this, one of these aspects is the composition of vehicles at the intersection, this is because each vehicle has different acceleration variations in reaching normal speed conditions after stopping at the intersection. Analysis was carried out by observing video of traffic conditions at the Jl. Demak – Jl. Dupak, Surabaya on every approach. Observations were made on group vehicle behind line stop 12 m back until the group of vehicles exits the approach during the green phase, so that data on the composition of the vehicle group and the initial loss time that occurs for each green phase are obtained. The results of the analysis of the influence of vehicle composition on initial loss time using the vehicle group acceleration approach show that the initial loss time range that can occur is between 8.5 seconds to 14 seconds which is influenced by acceleration vehicle group.

Margorejo Underpass Route Choice Study: Reviewed from Traffic Analysis

2023-12-06T15:22:01+00:00

The signalized intersection at Ahmad Yani street and Margorejo street becomes an intersection with quite long delays at peak
hours. street Ahmad Yani is an arterial road that connects Surabaya to Sidoarjo. The presence of high frequency train tracks and a u-turn on the frontage road in front of Giant Maspion Square has resulted in reduced green time on the east side traffic light heading north. One effort to reduce this congestion is to build an underpass. Before an underpass is built, it is necessary to select an underpass route referring to the 1997 Indonesian Road Capacity Manual (MKJI). The results obtained in this final assignment are the determination of the Margorejo-Ahmad Yani route which is recommended for an underpass to be built because the large delay that occurs is 687 sec/smp on Jalan Ahmad Yani Sidoarjo-Surabaya; 1938 det/smp on Jalan Ahmad Yani Surabaya- Sidoarjo; 149 sec/smp on Jalan Margorejo; and 120 on the frontage road. The DS that occurred was 1.33 on Jalan Ahmad Yani Sidoarjo-Surabaya; 1.66 on Jalan Ahmad Yani Surabaya-Sidoarjo; 0.9 on Jalan Margorejo; and 0.22 on road frontage. The queue length was 648 secondary schools on Jalan Ahmad Yani Sidoarjo-Surabaya; 2422 junior high schools on Jalan Ahmad Yani Surabaya-Sidoarjo; 68 junior high school on Jalan Margorejo; and 18 junior high schools on the frontage road. With the construction of the Margorejo underpass, the DS on all sections will be 1,074 on Jalan Ahmad Yani Sidoarjo-Surabaya; 1,385 on Jalan Ahmad Yani Surabaya-Sidoarjo; 0.5 on Jalan Margorejo; and 0.07 on road frontage. Delays and long queues no longer exist because there are no longer traffic lights.
