Abstract

TRAFFIC IMPACT ANALYSIS OF BADUNG REGENCY GOVERNMENT CENTRE “MANGUPRAJA MANDALA” ON THE PERFORMANCE OF SURROUNDING ROADSABSTRACTTraffic congestion around Hanoman intersection especially during the rush hours when the employees of the Badung Regency Government Office Centre are coming to or going home from their offices has created long lines of traffic jammed cars along Sempidi Road and the Dalung-Sempidi Road. Therefore, an analysis on the performance of the road and intersections around the Badung Regency Government Office Centre is needed to be done. The aim of this study is to identify the values of Trip Generation by Badung Regency Government Office Centre, the performance of Jalan Raya Sempidi, Jalan Raya Sempidi-Dalung, and the Hanoman Intersection. The method used was based on the Indonesian Road Capacity Manual (MKJI), 1997. The result of the analysis showed that the impact of Trip Generation by Badung Regency Government Office Centre during peak hours is 1,414 pcu/hour. Degree of Saturation on Sempidi Road increased from 0.93 to 0.97, and the Level of Service in E. Degree of Saturation on Sempidi-Dalung Road increased from 0.67 to 0.93 and the Level of service decreased from C to E. Degree of Saturation on Hanoman Intersection increased from 1.59 to 1.83 and the Intersection Delay increased from 160-109 to 229-150, and Level of Service in F. The traffic congestion in Raya Sempidi and Raya Sempidi-Dalung road are caused by the delay in Hanoman Intersection, therefore the problem in Hanoman Intersection must be solved. With the availability of land in the Northern and Southern gate of Badung Regency Government Office Centre, the solution can be in the form of establishment a U-Turn.

Abstract

Abstract: Cargo Terminal which has 70 units space is holding control of freight passing through the city center and as a place of loading and unloading of goods vehicles which do not have a warehouse. However, the activity of loading and unloading of goods is still widely practiced in the right of way which causes traffic jams. This triggers the Denpasar government to develop Terminal Kargo Denpasar  so as to supply the demand for parking and loading and unloading activities. The purpose of this study was to analyze the characteristics of the parking and future parking needs in developing Terminal Kargo Denpasar  . The method used to obtain data through direct surveys such as  inventory survey and survey cordon parking and secondary data obtained from the relevant agencies. The analysis shows the volume of parking of vehicles is 44,5 vehicles / hour, parking capacity is 36 vehicles / hour, parking supply as much as 372 vehicles and 4 for Parking Index that indicates there has been a problem of parking in the Terminal Cargo Denpasar. It is show Terminal Kargo Denpasar  has been unable to supply activity goods vehicles. The amount of the parking requirements for development of Terminal Kargo based on parking characteristic analysis are 101 spaces.

Abstract

In 2019 there are indication of decresed performance of Padangbai Port which can be seen from the long vehicles queues. Decline in performance is due to the high volume of vehicles unsuitable availability of facilities and infrastructure. This condition is exacerbated by the use of Padangbai Port to also serve the crossing to Nusa Penida. Damage to the pier or bad weather can also be the cause of reduced port performance. As an evaluation of the problems in 2019 and the impact of the Covid-19 pandemic in 2020, an analysis of operational performance evaluation is needed. To get ideal operational performance in the future, an analysis of the needs of ships, docks and ideal facility space is needed. The analysis is based on the prediction of the volume of passengers and vehicles by taking calculation from effect of the opening of the Banyuwangi - Lembar crossing route, which operates from 2021. In this study, the analysis of operational performance ata Port Padangbai in serving route Padangbai – Lembar was based on the Regulation of DJPL No. HK/103/2/2DJPL-17. The prediction of passenger and vehicle volume is carried out using 4 methods whics is growth factors based on GRDP, based on population growth, based on vehicle growth and regression analysis. From the 4 prediction methods, a representative prediction result will be selected. The calculation of ideal number of ship is based on the load factor and the calculation of the ideal dock is based on the ideal BOR value. The method of calculating the ideal facility space based on KepMen Perhubungan No. KM 52 Tahun 2004. The result show that the performance level of Port padangbai in 2020 is waiting time 13 minutes, approach time 19 minutes, ET/BT 63,42%, BOR in 2020 49% and BOR in 2019 85,74%. Prediction result of passanger and vehicle volume did not show a significant increase in the future. Result of the calculation ideal number of vessels are in 2019 26 units, 2020 19 units, 2025, 22 units, 2030 26 units, and 2040 30 units vessel. The ideal number of dock based on the calculation result show in 2019 ideally there are 3 docks, from 2020 to 2030, ideally there are 2 docks and in 2040 ideally there are 3 docks. The ideal facilty space calculation obtained the land side existing facility space is still adequate for 2019, but the availability of parking areas for crossing vehicles is prone to shortages. Meanwhile, the availability of land side facilities is currently still adequate for 2020 to 2040. The availability of water side facilities is not sufficient enough from 2019 to 2040.

Abstract

Abstract. This study examines journey to work by train in Sydney and the relationship with urban form, socio-economic and demographic variables by using multiple regression model. Train modal share between area located close to and away from a rail station is compared by using analysis of variance. Results of analyses indicate that the proportion using train between area close to and away from rail station is significantly different. Several urban form variables are related to the proportion using train for work trips. However, when socio-economic factors are included in the analysis, car ownership is the main determinant for the proportion using train whilst urban form variable such as density does not have a significant influence. Although urban form variables are not the most important predictor for rail modal share, urban form does influence the proportion using train in different parts of the metropolitan region. The findings support the use of urban form policies to reduce the dependence on car. A variety of non-urban form factors that affect mode choice are also identified. Abstrak. Studi ini menganalisis perjalanan kerja dengan kereta api di Kota Sydney dan keterkaitannya dengan variabel bentuk kota, sosial ekonomi dan demographi dengan model regresi berganda. Penggunaan kereta api antara lokasi yang dekat dan yang jauh dari stasiun kereta api dibandingkan dengan menggunakan analisis varian. Hasil analisis memperlihatkan bahwa proporsi penggunaan kereta api antara lokasi yang dekat dan yang jauh dari stasiun berbeda secara signifikan. Beberapa variabel bentuk kota terkait dengan proporsi pemakaian kereta api untuk tujuan kerja. Akan tetapi, ketika faktor sosial-ekonomi juga disertakan, kepemilikan kendaraan pribadi menjadi faktor yang dominan, sedangkan variabel bentuk kota seperti halnya kepadatan, tidak memiliki pengaruh yang signifikan. Walaupun variabel bentuk kota bukanlah variabel terpenting terkait penggunaan kereta api, tetapi variabel bentuk kota juga mempengaruhi pemakaian kereta api pada bagian-bagian yang berbeda di wilayah kota metropolitan. Temuan dari studi ini mendukung penerapan kebijakan untuk mengurangi ketergantungan pada kendaraan pribadi. Berbagai variabel selain bentuk kota yang mempengaruhi  pemilihan moda juga diidentifikasi.

Abstract. Decreasing public transport use and increasing car dependence have been experienced in many cities in the world. The environmental impact caused by this trend is alarming. In order to achieve sustainable city, one of the targets is to increase the use of public transport and reduce VKT (Vehicle Kilometer Traveled). It is therefore important to study the commuting behavior of residents. Using Journey-to-Work (JTW) Census data for Sydney region (Australia), this paper focused on analysis of commuting preferences by bus. Two techniques were applied to study commuting behavior by bus, i.e. preference functions and Moran's I spatial statistic. Preference function was used to measure resident's commuting behavior by bus whilst Moran's I spatial statistic was applied to study the spatial association or interaction amongst zones and to test their statistical significance. The results showed that the commuting behavior of the workers was not stable spatially. This indicates that the use of one global parameter to estimate future travel is not appropriate. The change in the commuting preferences by bus toward distance maximization has led to the increase of travel distance and VKT. Spatial statistic showed that the interaction was positive for journey-to-work by bus.Abstrak. Penurunan penggunaan angkutan umum dan peningkatan ketergantungan pada pemakaian kendaraan pribadi telah dialami oleh banyak kota di dunia. Akibat negatifnya terhadap lingkungan sangat mengkhawatirkan. Untuk mencapai kota yang berkelanjutan, salah satu targetnya adalah dengan meningkatkan penggunaan angkutan umum dan mengurangi kendaraan-kilometer. Untuk itu sangat penting untuk mengkaji perilaku komuter. Dengan menggunakan Sensus Perjalanan ke Tempat Kerja di Kota Sydney (Australia), paper ini difokuskan untuk menganalisis preferensi komuter dalam melakukan perjalanan dengan bis. Dua metode diaplikasikan yaitu fungsi keinginan dan statistik spasial Moran I. Fungsi keinginan dipergunakan untuk mengukur perilaku komuter yang menggunakan bis, sedangkan statistik spasial Moran I dipergunakan untuk mengkaji keterkaitan spasial atau interaksi antar zona serta untuk menguji signifikansinya secara statistik. Hasil penelitian memperlihatkan bahwa perilaku komuter dari para pekerja tidak stabil secara spasial. Hal ini menunjukkan bahwa penggunaan satu parameter global untuk memperkirakan perjalanan di masa mendatang tidaklah tepat. Perubahan preferensi komuter dengan bis kearah memaksimalkan jarak telah mengakibatkan peningkatan jarak perjalanan dan kendaraan-kilometer. Statistik spasial memperlihatkan bahwa terjadi interaksi positif untuk perjalanan kerja dengan menggunakan bus.

Abstract

Isu strategis yang dihadapi dalam penyelenggaraan jalan dalam kota khususnya di Kota Denpasar adalah masalah kemacetan. Salah satu dukungan pemerintah adalah peningkatan kapasitas berupa pelebaran jalan dengan melakukan penutupan permukaan Tukad Teba sepanjang 3.2 Km mulai dari simpang Teuku Umar hingga di simpang Sunset Road. Keunggulan yang dimiliki oleh Vissim dapat merefleksikan kondisi lalu lintas di Indonesia. Tujuan dari penelitian ini untuk menganalisis kinerja ruas jalan sebelum pelebaran jalan, menganalisis kinerja ruas jalan setelah pelebaran jalan, dan menganalisis persentase perbedaan kapasitas, volume, kecepatan, kepadatan dari sebelum pelebaran dan setelah pelebaran (pre dan post test) dengan melakukan pemodelan menggunakan piranti lunak Vissim. Setelah uji validitas menggunakan uji Indenpendent Sample T-test dengan nilai signifikansi sebesar 95%, peningkatan kapasitas tertinggi dimiliki oleh ruas dari Sp. Soputan – Sp. Nakula sebesar 136.14 % dari kapasitas sebelumnya, peningkatan volume tertinggi terjadi pada ruas pada Sp. Teuku Umar – Sp. Soputan sebesar 139,67%, namun dengan kondisi simpang Sp. Teuku Umar – Sp. Soputan saja yang tidak mengalami pelebaran maka terjadi peningkatan kepadatan tertinggi sebesar 112,45 % sehingga terjadi penurunan tingkat pelayanan dari sebelumnya B di tahun 2016 menjadi D pada tahun 2019. Ruas setelah simpang Soputan sampai dengan simpang Sunset road yang mengalami peningkatan kapasitas akibat pelebaran menghasilkan penurunan kepadatan sampai -12,32% dan peningkatan kecepatan rata-rata sampai 75,01%.

Abstract

Development efforts in the vertical direction should have been better than in the horizontal direction which only requires land to the side. The emergence of new ideas certainly raises the pros and cons, most local geniuses are vertical purity, the compilation passes under the terraced infrastructure there is a feeling of flare/fatigue because it is bypassed by people. The aim of the study is to reveal the vertical relationship with the design of underpasses, and how community acceptance of underpass construction. The methodology used is complicated through interviews with Hindu scholars, Bali, which are then used as a basis for further observation for shareholders so that questionnaires can be prepared. The results of the questionnaire are data of the relationship between vertical and attitude of community acceptance towards underpass development. The data obtained were analyzed by Logistic Regression. The results of the study of vertical simplicity are local wisdoms that need to be discussed and agreed in this modern era. Furthermore, the results of the analysis show that there is a relationship between vertical purity and uneven plot intersection height, as evidenced by the acceptance of the hypothesis at the significance level ? = 0.05. The results of the analysis show "significance <?" or (0.033 <0.05), this means vertical purity, which means significant effect on underpass height design. Alternative designs also need to reduce underpass differences. Invitations are made very necessary as a legal umbrella for the design and manufacture of underpasses. Keywords: Vertical purity, underpass, cemer/leteh, alternative design.

Abstract

Car dependence is a fundamental problem in the sustainability of cities with low-density suburban sprawl. Increasing the use of public transport is one of the policy objectives commonly adopted to overcome this problem. It is essential to study journey to work travel behavior by car and bus. This paper applied preference function to analyze travel behavior and Moran’s I spatial statistic to evaluate the spatial association. The results indicated that the commuting preferences of residents have moved towards distance maximization. In general, bus was preferred for shorter distance trips whilst car was preferred for longer distance trips. Unlike car, by increasing distances from the Central Business District, residents tended to use bus for shorter distance trip. A significant positive spatial association was identified for both the slope preferences by car and bus where zones with a preference towards longer or shorter trips tended to travel to zones with similar preferences.
