"Accident prone locations refer to locations having or susceptible to having, a greater than average number of accidents which are represented by outstanding figures of repetitive accident occurrences along the roads. Any appropriate application of remedial safety treatments will require ­an in-depth study to find the accident causations and the possible contributing factors. The present study adopts the combined approach of Systems Theory which proposes that accidents are the result of maladjustments in the interaction between the components of complex systems, and the Causal Accident Theory which tries to find the real causes of accidents by probing the events leading to each accident in detail. The case study was conducted at Gringsing Roundabout in Central Java and the intersecting roads, the data of which reveal a high frequency of accidents. The data were analyzed using cross tabulations to produce first-hierarchy and second-hierarchy accident causations. Results indicate that geometric features, as the predominant factors, lack compliance with the standards. The remedial safety treatment therefore focuses on geometric redesigning of the roundabout in compliance with geometric standards and traffic demand. A major change, in conjunction with other hazard reduction schemes along the roads, is also proposed to the existing roundabout. The proposed changes are expected to mitigate or remove the possible accident causes, thus reducing accident occurrences."

ABSTRACTCipularang Toll which connects two major cities of Jakarta and Bandung, has become increasingly crowded due to its much shorter travel time. The distance is now travelled 2 to 3 hours in regular traffic. Despite the beautifully landscaped highway, records indicate high number of accidents. The study aims to determine the location of the accident prone section and the relation of the driver 39 s field of view to road geometry, along KM 90 100. The research includes the collection of accident data during 2013 2015 as well as the road geometry data from the Hawkeye system. A 3 D simulated image using Vissim is produced and analysis was carried out on the road geometry based on the driver rsquo s view. The results indicate that there are six accident prone locations along the observed link and accidents involving passenger cars are prominent. The study also reveals sections which are not geometrically designed as one phase and curves with limited sight distances in which they are considered as accident prone."

"Deceleration rate, time to collision and impact speed have been commonly employed as accident risk indicators. However, it is hard to assess the level of accident risk since these indicators have not been developed with measurable score criteria. This study focuses on the determination of measurable risk indicators which could be used to assess accident risk level and to determine more appropriate accident risk management strategies by using the descriptive qualitative approach. The data were collected from a braking maneuver test conducted on a dry and level closed circuit course. Risk was a function of accident probability and its possible consequences, while accident probability was determined based on the safety factor, i.e. the ratio of available stopping sight distance (ASSD) to minimum SSD (MSSD), which was used to determine the margin of safety. Subsequently, accident consequence was determined using the impact speed at a predicted point of collision along the braking distance path. The results show that accident risk could be easily determined using the proposed indicators, whilst an objective and appropriate accident risk management strategy could be determined based on the minimum margin of safety value which could be obtained from each risk exposure."

"Keselamatan berlalu lintas adalah permasalahan utama dalam negara berkembang seiring dengan sistem transportasi dan infrastruktur yang juga berkembang dengan pesat. Sementara tingkat kesadaran dalam mencegah kecelakaan sangat rendah dan mengkhawatirkan. Dampak yang terjadi tidak hanya berkisar pada kerugian fisik, tetapi juga dapat menghilangkan sumber daya. Depok, sebagai sumber administratif yang sedang berkembang juga mempunyai masalah dalam bidang transportasi dan infrastruktur.Tujuan dari peningkatan kesalamatan berlalu lintas adalah untuk menciptakan lalu lintas yang aman dan nyaman bagi para pengguna jalan. Penerapan TCT merupakan salah satu cara dalam mewujudkan pengingkatan keselamatan lalu lintas. Metode yang telah dikembangkan oleh jurusan transportasi dan perencanaan, Universitas Lund ini telah diterapkan di negara Swedia. Adapun penerapan metode ini dengan menganalisa jumlah kecelakaan yang diperkirakan akan terjadi (preventive) bukan berdasarkan kecelakaan yang sudah terjadi (curative). Langkah pertama yang harus dilakukan adalah menentukan lokasi yang rawan atau beresiko terhadap kecelakaan. Kemudian dilanjutkan dengan menganalisa tindakan yang dapat menyebabkan kecelakaan dan langkah apa yang dapat diambil untuk mencegah terjadinya kecelakaa. Hasil akhir analisis TCT ini dapat berupa larangan atau peringatan yang berupa rambu, bangunan, maupun fasilitas lainnya.Inti dari TCT adalah mengidentifikasi dan mencatat konflik-konflik berdasarkan pengamatan. Kejadian yang terjadi dapat digolongkan berdasarkan karakteristik kedekatan antara sebab akibat kecelakaan. Dengan menerapkan TCT diperkirakan menurunnya jumlah kecelakaan dan meningkatnya rasa aman dan nyaman bagi seluruh pengguna jalan.

Traffic safety is the main problem in developing country as well as the increasing of transportation and infrastructure. Mean while, the realization of accident preventative is apathetic. The effects of this situation are not only in physical but influence the sources. Depok, as developing administrative city has the same problem in transportation and infrastructure.The aim of traffic safety improving is to create comfortable and safe situation for people. The implementation of TCT is the certain way to make improving traffic safety. The method has improved by Transportation and Developing Department in University of Lund and they have implemented in Sweden. The analysis includes the amount of accident that will happen (preventive) not the accident that had happened (curative). For the first running is to state the area which mostly has the risk accident. Then, to analyze the causes of accident and what should be done to prevent the accident risks. The results of analysis are the traffic regulations as like as traffic sign, police post, or other buildings and facilities.The point of TCT is identification and conflict records base on analysis. The incident categorizes base on the nearby characteristic between reason and effect of accident. Through TCT implementation may be decreasing the rank of accident and increasing comfortable and safe situation for traffic users."

Dam is an infrastructure that has many benefits for human survival such as a water reservoir which is the solution to the current crisis of clean water in Indonesia. The clean water crisis was anticipated by the government by constructing dam in critical areas with a target of 29 dams to be completed by 2019. But it is not uncommon for work accidents to occur in dam construction that have an impact starting from injuries or minor injuries to fatal ones such as death. So that, it is necessary to identify and analyze potential hazards early to prevent such accidents. This research aims to develop a safety plan for preparatory work of dam construction and cofferdam constcution by identifying potential hazards that may occur in each work package by reviewing work methods, work activities, and WBS-based dam construction that has been standardized using the qualitative approach method. From the research, there are 20 risk sources of OHS that have the highest potential hazard in preparation work and cofferdam which were dominated by human resources and tools. Furthermore, safety plan had been developed based on the OHS risk sources obtained from the WBS for preparatory work and cofferdam."
