Abstract

There are two road condition survey methods commonly used, the roughness-based equipment such as NAASRA and the distress and severity type road evaluation method as presented by ASTM D-6433. The objective of the study is to evaluate the relationship between road condition obtained from roughness type equipment and road distress. To achieve the objective, a condition survey using the two methods were performed on two road segments in the East Java Provincial road system. Data obtained from the field was evaluated to obtain International Roughness Index (from NAASRA) and Present Condition Index value (from field condition survey). The results show that the two methods provide a comparable result when the distress type is of un-even surface such as rutting and bumping. A slight different result is observed when the major distress occurred in the road is of crack-type such as fatigue and block cracking.

Abstract

Transportation problem is complex because the growth of road infrastructure is not proportional to the increase in the number of travels. This is indicated by the increasing levels of private vehicle ownership, numer of trips, insufficient of public transport services, and limited road infrastructure. In this study, the pattern of mass transit, as stated in Law No. 22 of 2009, was examined. Analyses were performed using Confirmatory Factor Analysis and Structural Equation Modeling. The results showed that the variables of Travel Origin and Destination, Travel Patterns, Willingness, and Ability to Pay explained approximately77.0% of the variation in the Guided Busway Needs variable. In addition, Travel Origin and Destination, Travel Patterns, and Willingness and Ability to Pay have positive and significant impact on the Guided Busway Needs.Keywords: mass transit, guided busway, origin destination travel, travel patterns, willingness and ability topay.

Abstract

In this study, traffic accidents occurred on roads in Batu, East Java, were observed. Based on these traffic accident data, a model was built to relate the number of motorcycle accidents with the availability of road shoulders, traffic flow, and traffic speed. The results indicate that the availability of road shoulders potentially reduce the number of motorcycle accidents. Conversely, increasing the speed and traffic flow potentially increase the number of motorcycle traffic accidents on the roads in Batu.Keywords: motorcycle accidents, road shoulders, traffic flow, traffic speed

Abstract

Abstract During road reconstruction period, a negative impact was imposed on road users and the surrounding environment. These impacts are the result of the work zone which is used as working space and road reconstruction. This work zone is potential to influence the drivers stress and to decrease road traffic performance such as travel delays, congestions and road accidents. Guidelines for green (environmentally friendly) infrastructure defined in New Road Construction Concept (NR2C) in European infrastructure vision 2040 concept, can be used to mitigate this negative impact. Twenty projects of Balai V National Roads Improvement in East Java, and Balai VIII in Bali for fiscal year 2013 is used as a case study. Descriptive method used for the discussion of case studies. Management traffic safety in work zones assessed the suitability of the setting up of signs, markings and guardrail. Shift arrangements work during the day (peak hours) or night (off peak hour), is used as an indicator of the negative impact of road users and the environment. The analysis showed that the work zone management in the implementation of national road reconstruction projects toward green (environmentally friendly) construction concept. It is shown from the implementation of safety attributes average 68%, and the implementation of the reconstruction in the off peak hours by 55% of the projects. Keywords: road reconstruction, work zone, negative impact, green construction  Abstrak Pada saat pelaksanaan rekonstruksi jalan, dampak negatif akan  terjadi pada pengguna jalan dan lingkungan sekitarnya.

Abstract

One of the advances in the development of a model of traffic accidents is indicated by the availability of generalized linear models (GLMs) and generalized additive models (GAMs) in the regression analysis. This paper will discuss the motorcycle accident prediction models using GLMs and GAMs on the north-south road corridor in Surabaya. The first part will discuss the model prediction of traffic accidents, as well as providing a brief review related to the use GLMs and GAMs in building models of accidents. Furthermore, application examples of GLMs and GAMs will be presented. To determine the effect of non-linear in each explanatory variable, smoothing the GAMs will be conducted in each variable gradually. Model diagnostic and intrepretations will be done in the final part. The results of the application of GLMs and GAMs indicates that the development of predictive models of motorcycle accidents with statistical methods can be used to diagnose problems in road safety. GAMs produces better models than the GLMs in which its condition without using the Poisson distribution, as shown in the difference in the value of the model parameter R-sq.(Adj), deviance explained, and the GCV score. By using the Poisson distribution with a log link-function, it appears that GLMs and GAMs produce the same model parameter values.

Abstract

The low standard of National road is continuously reconstructed to establish Trans National connectivities. During the reconstruction period, the loss of road user costs and the negative impacts for surrounding environment were inccurred. Predicted losses of road users have not been conducted, so that it is important to be investigated. Initially, road performances were analyzed during road reconstruction. The road performances were analyzed using a descriptive method. Road performance variable includes running costs referred to the Bina Marga guidelines of Pd - T-15 -2005- B. National road reconstruction project in fiscal year 2013 is used as a case study. The results of the analysis are obtained as follows: 1) speed (Vm) can be predicted from the exponential relationship model in which degree of saturation in pre-reconstruction (DSp) is used as a generator variable. This generator variable is predicted declining at 6 km/h (DSp = 0.1);  2) The traffic flow (Qm) is predicted by multiplying the current pre-reconstruction flows with a factor of Fq. Traffic flows is predicted declining by 28% (Fq = 0.72); and 3) The degree of saturation (DSm) is predicted by a factor of Fds and estimated to increase by 30% (Fds = 1.3).

Abstract

Abstract The train is a mode of transportation that has the ability to transport passengers and goods in bulk, saving energy, saving the use of space, has a high safety factor, low pollution levels, as well as more efficient to transport over long distances. However, railway performance has a major problem, as reflected in the delay, with the main indicators of speed and travel time. The purpose of this study is to optimize travel time and determine the factors that cause train delays. In this study, train speed was simulated using the software developed based on Newton’s equation of the dynamic equations and applied in the area of Regional Operations 8 Surabaya, for Bojonegoro-Kandangan corridor. The results indicate that the train travel time can be accelerated and the accretion of coach 1 to 5 coaches for all train classes does not add the travel time significantly. Keywords: speed, travel time, train performance, train delays  Abstrak Kereta api merupakan moda transportasi yang memiliki kemampuan mengangkut penumpang dan barang secara massal, hemat energi, hemat penggunaan ruang, memiliki faktor keamanan yang tinggi, memiliki tingkat pencemaran yang rendah, serta efisien untuk angkutan jarak jauh.

Abstract A thriving city should have a reliable public transport system. A continued decline in the performance of services can not be separated by a detachment of people using public transport, as uncomfortable and unreliable existing services, until unresolved overlapping route yearly by the regulator. Restructuring the route network and preposition institutional arrangement of public transport management are needed to improve public transport services in the community. Restructuring the route network into two, namely: first, the subsidiaryp route network that serves the main line of Jember city use the concept of road based public transport (BRT) with medium buses; second, develop twigs routes of feeder line to serve distrct road network in urban areas. Formulation of public policy was conducted through four stages: formulation of the problem, preparation of policy agenda, selection of policy alternatives to solve the problem, and determination of the policy to minimize the two groups resistance (pro and contra).                                                                                  Keywords: policy formulation, policy agenda, problem solving, policy setting  Abstrak Sebuah kota yang berkembang harusnya memiliki sistem angkutan umum yang dapat diandalkan. Terus menurunnya kinerja pelayanan tidak lepas dari menjauhnya masyarakat menggunakan angkutan umum karena tidak nyaman dan tidak handalnya pelayanan yang ada, hingga overlapping lintasan trayek yang sudah bertahun-tahun tidak terselesaikan oleh regulator. Penataan kembali jaringan trayek dan kelembagaan pengelolaan angkutan umum diperlukan untuk meningkatkan pelayanan angkutan umum di tengah masyarakat. Penataan jaringan trayek dilakukan terbagi dua, yaitu: pertama, jaringan trayek cabang yang melayani jalur utama perkotaan Jember menggunakan konsep angkutan umum berbasis jalan dengan armada bus sedang; kedua, jaringan trayek ranting yang melayani jaringan jalan kabupaten di kawasan perkotaan yang semakin berkembang. Formulasi dalam kebijakan publik dilakukan melalui empat tahapan, yaitu: perumusan masalah, agenda kebijakan, pemilihan alternatif kebijakan untuk memecahkan masalah, dan penetapan kebijakan dilakukan untuk mengurangi resistensi dua model kelompok (pro dan kontra). Kata kunci: perumusan kebijakan, agenda kebijakan, pemecahan masalah, penetapan kebijakan
