Abstract

Accident prediction models is related to the quantification of the relationship betweenaccidents that occured at certain location with factors that influence it at a particular time. Themodels could provide ideas how each variable contributes to the accident that occured at aparticular location. The purpose of the strudy was to develop toll road accident prediction models byconsidering hourly traffic flow. Microscopic analysis result shows that the relationship betweenaccident frequency and hourly traffic can be represented by exponensial step-functions. Up to 700vehicle/hour accident frequency increases exponentially, then it decreases exponentially as trafficflow increases furthermore. This trend was common for total, single-vehicle, and multi-vehicleaccidents. Model prediksi kecelakaan merupakan kuantifikasi hubungan antara kecelakaan yangterjadi pada suatu lokasi dengan faktor-faktor yang berpengaruh pada waktu itu. Model prediksidapat memberi gagasan bagaimana masing-masing variabel tersebut berkontribusi menyebabkankecelakaan yang terjadi di lokasi tersebut. Penelitian ini bertujuan untuk mengembangkan modelprediksi kecelakaan yang terjadi pada ruas jalan tol dengan berdasarkan volume lalu lintas per jam(hourly traffic flow). Analisis secara mikroskopik dengan menggunakan volume lalulintas per jamsebagai variabel bebas menunjukkan bahwa hubungan antara besarnya frekuensi kecelakaandengan volume lalulintas per jam berbentuk eksponensial bertingkat. Sampai dengan nilai volumelalulintas 700 kendaraan/jam hubungan frekuensi kecelakaan dengan volume lalulintas per jamdapat dinyatakan dengan fungsi eksponensial positif, sedangkan di atas nilai volume lalulintas 700kendaraan/jam hubungannya dapat dinyatakan dalam bentuk fungsi eksponensial negatif. Hal iniberlaku baik untuk kecelakaan total, tunggal, maupun jamak

Abstract

Pemantauan gunung api merupakan salah satu bidang penerapan Wireless Sensor Network (WSN). WSN digunakan pertama kali untuk pemantauan gunung api di gunung Tungurahua, Ekuador Tengah pada tahun 2004. Selanjutnya diterapkan pada riset di gunung Reventador, Ekuador Utara dengan 16 sensor digunakan untuk menangkap sinyal seismik dan akustik. Pada kedua riset ini, desain jaringan dan algoritma dibangun untuk menangkap raw-data sinyal seismik dan akustik, dan mengirimnya ke base station. Seperti dua riset sebelumnya, proyek OASIS membangun WSN yang robust untuk memperoleh raw-data sebanyak-banyaknya dengan real time, kontinu dan kualitas sinyal yang high-fidelity. Berbeda dengan riset WSN untuk pemantauan gunung api sebelumnya, riset Rui Tan, dkk. dan Guojin Liu, dkk. mengembangkan WSN untuk pemantauan gunung api secara real time, in-situ dan long-lived tanpa transmisi raw-data ke base station. WSN dan algoritma didesain dengan membangun algoritma pemrosesan in-network untuk mendeteksi gempa vulkanik, menentukan onset time dari gelombang yang biasa muncul pada saat terjadi gempa.

Abstract

ABSTRACT To determine the fare of city transport, the local government as a regulator has to consider two different interests those are interest of  the operator and interest of  the user. The operator wishes the fare would give high profit, while the user affected wishes the cheapest fare. The factors to the fare rate are vehicle operation cost, and ability to pay of the users. This study is focussed as the discussion of the ability to pay of the users.Two approaches were used to find and the ability to pay of users those are the ability based on user perception (willingness to pay) and ability based on budget allocation for transport (ability to pay).The factors used to determine the Ability To Pay and Willingness To Pay are house size, family income, transportation needs, total transportation cost and trip distance. Data was collected by questioner and interviewing the respondent at four kecamatan i.e. Gayamsari, South Semarang, East Semarang and Central Semarang. It was found the public transport which was dominated by man, of  20 – 50 year old, and elementary education level. Keywords : Willingness to pay, ability to pay

Abstract

ABSTRACT Semarang and Surakarta have different characteristic on structure and urban growth. This difference affects on urban public transport service in those cities. Aim of this research is to know the difference characteristic of urban public transport service between Semarang and Surakarta. The analysis method is comparing urban public transport service generally with transportation service and especially with public transport service, those are effectiveness and efficiency. Result of this research can be used for local government as one of the review on making of urban public transport system insight. The result of this research shows that the difference on urban structure of Semarang and Surakarta affect on urban public transport service. The urban structure of Semarang with concentric design and add with its ring radial road network cause almost all of public transport track through the down town area as the centre of all activities, mean while the urban structure of Surakarta with its grid road network tendency to spread the movement into all over the town that cause people activity spread relatively. These circumstances cause urban public transport track also spread all over the town following road network up to its hinterland. Some proposed to ascend urban public transport system service in Semarang needs an evaluation of urban public transport service more efficient with reduce or change public transport moda with that whose have bigger capacity so that can reduce traffic problem in down town area, mean while Surakarta needs to cooperate with its hinterland because almost all of urban public transport that are operating in Surakarta having the beginning and ending terminals outside of its jurisdiction.

Abstract

One of the public transportation in Bekasi which serves commuters Jabodetabek is provided by the railroad-based public transport. However, as a satellite city of Jakarta which has more than two million people of population has a massive movement toward Jakarta, Bekasi city transport system is still far from a concept of a seamless services that accomodate the needs of commuters traveling. This research used techniques of qualitative and quantitative method, then though descriptive statistical analysis technique, analytical technique Service Quality (Servual, and Important-erformance Analysis (IPA) which the respondents are passengers of a Jabodetabek Commuters Line. The results suggest that modal choice behavior towards and from the station (Access Mode) as well as from the station to the destination (Egress Mode) is influenced by the ‘Time Value’ and ‘Cost of Transport’. When the modes offered a great time to the station, the more unattractive to the people, as the greater respondent's income make them free to choose the modes, a faster transport time services but requires a greater transport costs.

Abstract

Kalibanteng Intersection is one of primary node in west part of Semarang City. It is a signalized intersection which shaped roundabout. It lies on the truck track from west to east of Java Island, which is crossed over by Flyover Yos Sudarso – Siliwangi and Flyover Sudirman – Siliwangi. Formerly, the flyover is designed for Siliwangi – Yos Sudarso vice versa. The flyover could decrease truck volume from east to west, on the contrary heavy vehicle movement is still overburden Kalibanteng Intersection capacity. On 2018, it is planned that Ahmad Yani Airport access road will be diverted. Thus, it is important to increase Kalibanteng Intersection performance, and accommodate the airport access divertion plan at a time. This research is aimed to identify the existing movement pattern at Kalibanteng Intersection, to evaluate the existing signalized intersection performance, to develop a simulation of two way management on Kalibanteng Flyover, to analyze the movement pattern due to the implementation of two way management on the flyover, and to analyze the signalized intersection due to this management. The results show that the highest movements in Kalibanteng Intersection are the movement from Siliwangi to Yos Sudarso (which is dominated by heavy vehicle) and from Siliwangi to Sudirman (which isi dominated by light vehicle and motorcycle), and will keep on increasing in the future. These movement greatly contribute on intersection performance. This shows that the utilization of the flyover for two-way movement can be considered with mode type limitation. Using two-way flyover, the performance of Kalibanteng signalized intersection will increase.

Abstract

Bridge is a part of road infrastructure system which must be well managed. One of the maintenance strategy is a whole year maintenance to keep the bridge in good condition during its design life. With tight budget, a comprehensive decision is needed to prioritize which bridge needed the most. The purpose of this research is to identify and determining the criteria and sub criteria, the scale of priority handling, and value sensitivity in maintenance activities bridge in of national roads island bangka. Analytical Hierarchy Process (AHP) was used to provide qualitative space for experts to share opinions and complemented with quantitative analysis. This method was also as an applicative tool to support BMS (Bridge Management System) program by using more measurable approach. This research used six criteria and 18 sub-criteria. The criteria with the highest and lowest weight were general condition of the bridge and social and regional development aspect, respectively, while the sub-criteria with the highest and lowest weight were watershed condition and the number of public facilities served, respectively. The resulst on 74 researched bridges showed that Segambir bridge became the bridge with the most priority to be maintained, followed by Birah and Nangka bridges.

Abstract

Nowadays, the government plan to develop toll road intercity network, which connect Jakarta and Surabaya city, Either Roadway or toll road that connecting one town to another represent supporting tools towards economic activity. Lacking in road connetion services, can cause high expense economics which finally encumber society as a whole.  In the last decade, government find difficulties to increase road connection service, either from capacities or also from its qualiaty side. Recent years, the maintenance cost allocation seems to short to fulfill the requirement standard of maintenance. Therefore the toll road constructed by private sector should be mobilize as one of the society participation form in the infrastructure development, besides reduce the monetary burden to government. It is need to learn furthermore, whether the toll road construction oppose against the principle of environment conservation. Principles of sustainable development also consider to the economics aspect. Both aspects, economic and environment have to be considered and in line together. In evaluating a big project, there are some method which could direct or indirectly calculate its cost benefit. Its should be recognized whether the toll road construction comply with the financial, economics and social aspects. In the view of economics, toll road construction investment could mobilized a big amount of money and offering many vacancies. While in economics critism which produce a high unemployment, it should stimulate the growth of economics in a broad way. Meanwhile government should not be encumbered to make such road improvement, which is very difficult to fulfill nowadays.Keywords: toll road investment, community participation, sustainable developmentPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3939[How to cite: Riyanto, B., 2006, Pengembangan Jaringan Jalan Tol antar Kota dalam Perspektif Sistem Transportasi Berkelanjutan, Jurnal Media Komunikasi Teknik Sipil, Volume 14, Nomor 1, pp. 95-105]

Abstract

National and provincial road networks have a major role to provide high accessibility and mobility to all community. Their services both functional and structural, therefore, need to improve continuously. Current figures show that from 2002 to 2003 the length of the road networks increased 8.07%. During these years, it was found that the road investment increased 28.61% and AADT increased 8.80%.  However, it was not followed by the road networks performance, such as the IRI increased 39.5%, the road networks with SDI>50 increased 84.01%, and the road network in bad condition increased 64.92%.  The purpose of this paper is to highlight and review technical aspects of the road networks performance particularly their quality standard achievement. Finally this paper discusses reasons of decreased quality performance of the road networks whilst increased investment and maintenance cost occurred.
