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

ROAD RECONSTRUCTION WORK ZONE MANAGEMENT TOWARD A GREEN CONSTRUCTION CONCEPT

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.

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
