Modelling of Motorcycle Accidents at Non-Exclusive Motorcycle Lane Junctions in Malaysia

In Malaysia, motorcycles constitute more than half of the total registered vehicles and contribute to more than 60% of casualties (death, hospitalised and slight injury) to total traffic accidents. In the 1990-2000 period, almost 3,000 motorcyclists were killed every year in traffic accidents. To overcome such problems, the exclusive motorcycle lanes have been constructed along the major trunk roads in Malaysia. However, not much work has been done to address junction accidents involving motorcycles. As such, a detailed study on this area has been carried out to allow traffic engineers to establish appropriate junction treatment criteria specifically designed for non-exclusive motorcycle lane facilities.A total of 104 junctions in Hulu Langat, Klang, Kuala Langat and Petaling districts with 1,095 injury related motorcycle accidents in the period 1997-2000 were included in the study. The generalised linear modelling with Poisson distribution was used to develop the model. The variables of the model were examined using univariate and multivariate analyses. The final models revealed that traffic flow entering the junction, approach speed, lane width, number of lanes on major road, shoulder width, junction control and land use were significant in explaining motorcycle accidents. Meanwhile, pedestrian flow, number of lanes on minor road and number of intersecting legs were not significant in explaining motorcycle accidents. Non-motorcycle flow on major road had the highest effect on the probability of motorcycle accidents at junctions. The final models allow traffic engineers to decide the appropriate intervention levels for junction treatment with respect to motorcycle accidents. Using the final models, design parameters for junctions may be changed to achieve the appropriate safety levels for them. The decision on whether to allow motorcycles to pass through a junction without treatment to it or the need for special end treatment to minimise motorcycle conflicts at junctions can be objectively carried out based on the model, and this can easily be done using the software developed in this study. Apart from the software, a series of design curves relating major road and minor road flows at junctions with typical shoulder widths of 0.0 m, 1.0 m, 1.5 m, 2.0 m and 2.5m have been established. The design curves were developed based on the number of Personal Injury Accidents (PIA) of 1-PIA per year. These design curves also enable traffic engineers to decide the need for special end treatment of the junctions

Model Kecelakaan Sepeda Motor Pada Suatu Ruas Jalan

Recently, motorcycle population in Indonesia is increasing rapidly. Meanwhile, the number of accidents involving motorcycles is higher than that of other motor vehicles. Based on the problem, it is important to find out a solution so that the road transportation safety can be created. The objective of this study is to model motorcycle accidents on the road. The dependent variable, as a response variable, is the number of motorcycle accidents and the independent variables are traffic volume, speed, lane width, lane number, and shoulder. The road accident data were collected from 18 roads in four areas, including Surabaya City, Malang City, Malang Regency, and Batu City. Modeling analysis employed a Generalized Linear Modeling (GLM) method. The results indicated that the model can be used to describe the actual condition of the road accidents. Moreover, it is also showed that the motorcycle accidents are significantly influenced by volume, speed, lane width, lane number, and shoulder variables. High volume and speed will increase accident risks, but the increase in lane width, lane number, and shoulder will decrease accident risks

Kajian Dampak Relokasi Terminal Gadang Kota Malang Terhadap Biaya Operasional Kendaraan Dan Pengguna Angkutan Kota

Terminal angkutan umum ini juga menjadi prasarana transportasi penting di Kota Malang, namun seiring dengan rencana tata ruang wilayah (RTRW) kota malang setelah bulan 14 agustus 2009 Terminal Gadang dihentikan fungsinya dan digantikan oleh Terminal Hamid Rusdi, adanya permasalahan baru yaitu terganggunya kinerja operasional angkutan umum. Pada penelitian ini untuk analisanya menggunakan perhitungan jumlah armada angkutan kota ideal, jumlah penumpang, biaya operasional kendaraan, dan tarif. Sedangkan untuk menghitung jumlah armada ideal yaitu perhitungan faktor muat, waktu siklus, waktu antara. Untuk perhitungan jumlah penumpang peneliti membandingkan jumlah penumpang sebelum dipindahkan dengan jumlah penumpang setelah dipindahkan sehingga nanti dapat mengetahui perbedaan jumlah penumpang. Untuk perhitungan biaya operasional kendaraan digunakan perhitungan biaya tetap, biaya tidak tetap, dan overhead. Untuk perhitungan tarif menggunakan pembagian antara biaya operasional kendaraan total dengan jumlah penumpang total. Hasil proses perhitungan ini yaitu didapat jumlah penumpang untuk taryek LDG sebesar 167 penumpang dan untuk taryek ABG sebesar 165 penumpang. Sedangkan perhitungan jumlah armada ideal didapat sebanyak 102 armada untuk taryek LDG dan trayek ABG sebanyak 120 armada. Perhitungan biaya operasional kendaraan sebelum direlokasi untuk trayek ABG sebesar Rp 251.495,00 untuk trayek LDG sebesar Rp 232.955,00, setelah direlokasi untuk trayek ABG sebesar Rp 316.416,00 dan untuk trayek LDG sebesar Rp 289.636,00. Setelah didapat perhitungan biaya operasional dan jumlah penumpang didapat perhitung tarif, tarif yang didapat sebelum direlokasi untuk trayek ABG sebesar Rp 700,00 dan trayek LDG sebesar Rp 300,00, setelah direlokasi didapat besarnya tarif untuk trayek ABG sebesar Rp 1.400,00 dan trayek LDG sebesar Rp 1.200,00

Sedangkan menurut pengguna jasa truk, faktor yang paling berpengaruh adalah frekuensi keberangkatan dan selisih biaya pengiriman dengan persamaan utilitas (UKA-UTB) = -0,525 - 0,152 (∆X4(frekuensi)) dan (UKA-UTB) = -0,057 - 0,0000496 (∆X2(selisih biaya)), hal ini juga sesuai dengan karakteristik pengiriman lewat truk yaitu memiliki frekuensi pengiriman barang yang tinggi dan dengan alasan murah

The Policy and the Strategy of the Provision of Bicycle Lane in East Java, Indonesia

Understanding the characteristics of the cyclists and stakeholders’ preferences towards the provision of bicycle lanes is the first step for sustainable transportation. The Government support for providing bicycle lanes can increase the number of cyclists, thus reducing the noise and air pollution, and providing safety, discipline and smooth traffic. Therefore, is required a study of a policy strategy about the provision of bicycle lanes. The aim of this study is to obtain a policy for handling the provision of bicycle lanes based on internal and external factors by considering the preferences of cyclists, road users and stakeholders. Data was collected by interviewing all stakeholders, i.e. the staffs from the City Government of the city of Malang, Jember, and Surabaya and the Department of Public Work Bina Marga of East Java. The analytical method used is SWOT Internal Factor Evaluation-External Factor Evaluation (SWOT IFE-EFE).Analysis of matrix of external and internal factors for the provision of bicycle lanes explains that positions of the current condition and the future condition are in the cell V (2.451; 2.493) and in the cell I (3.338; 3.135) respectively. The position of the cell V and the cell I indicates that the provision of bicycle lanes under development is a position of grow and develop.The development strategy can be applied through vertical integration thus all the strategic elements of government and stakeholders are able to jointly reformulate the strategy, starting from the preparation of legal protection for the provision of bicycle lanes in the neighborhood (“RT/RW”) of sub-district. The city authority is expected to reinforce the operational implementation. Meanwhile, the preference weight towards the provision of bicycle lanes of road users and stakeholders is 83.7%. Herewith the provision of dedicated bicycle lanes is required

MODEL KECELAKAAN SEPEDA MOTOR PADA RUAS JALAN DENGAN MENGGUNAKAN PENDEKATAN GLM

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 spee
