PMID: 37869200 DOI: 10.3389/fpubh.2023.1160317

INTRODUCTION: Driving fatigue has been shown to increase the risk of accidents and potentially fatal crashes. Fatigue is a serious risk that some drivers do not take seriously. Previous studies investigated the effects of driving fatigue in the Malaysian oil and gas transportation industry by employing survey questionnaires. However, they did not explain the behavior of fatigue. Besides, these results required validation by a more reliable method that can describe how fatigue occurs.
METHODS: Thus, in this study, we used the Psychomotor Vigilance Test (PVT-192) and a short survey to address driving fatigue behavior and identify the influences of driving fatigue on driving performance in real life (on the road) with actual oil and gas tanker drivers. The total participants in the experimental study were 58 drivers.
RESULTS: For the analysis, a Wilcoxon Signed Ranks Test, Z value and Spearman's rho were used to measure the significant difference between the pre and post-tests of PVT and the correlation between the fatigue variables and driving performance.
DISCUSSION: During the experiment's first and second days, this study's results indicated that driving fatigue gradually escalated. Likewise, there was a negative correlation based on the test of the relationship between the PVT data and the driving performance survey data. Additionally, the drivers suffer from accumulative fatigue, which requires more effort from the transportation company management to promote the drivers awareness of fatigue consequences.

Fulltext Analysis of motorcyclist riding behaviour on speed table

Yuen CW, Karim MR, Saifizul A

ScientificWorldJournal, 2014;2014:236396.
PMID: 24991638 DOI: 10.1155/2014/236396

This paper focuses on the study of the change of various types of riding behaviour, such as speed, brake force, and throttle force applied, when they ride across the speed table. An instrumented motorcycle equipped with various types of sensor, on-board camera, and data logger was used in acquiring the traffic data in the research. Riders were instructed to ride across two speed tables and the riding data were then analyzed to study the behaviour change from different riders. The results from statistical analysis showed that the riding characteristics such as speed, brake force, and throttle force applied are influenced by distance from hump, riding experience, and travel mileage of riders. Riders tend to apply higher brake intensity at distance point 50 m before the speed table and release the braking at point -10 m after the hump. In short, speed table has different rates of influence towards riding behaviour on different factors, such as distance from hump and different riders' attributes.

PMID: 12862417

Injuries are a major public health problem in Malaysia. A cross-sectional study on the profile of injuries was conducted in four villages in the Jasin District of Malacca using a prepared questionnaire among the residents. A sample of 199 households was selected from the total of 385 by using the simple random method and personal interviews were carried out. Injuries were common (56%) among the family members within the period of one year prior to the survey. Home and residential injuries were the most common type (60.2%) followed by road traffic injuries and injuries at work place. Among the home injuries (68 cases), falls were the most common type of injuries encountered with most occurring in the evenings within the house compounds. For all types of injuries (113 cases), the majority (46.9%) preferred to seek treatment at government clinics and hospitals. Among the road injuries (29 cases), most occurred in the evenings and at nights. They were more severe in nature and some required admission to the hospital. The extremities were the most severe injuries among the home and road ones. Preventive strategies should be targeted towards the home and road injuries by environmental and behavioural changes together with community participation on injury prevention and control at district level.

Seat belt use in a developing country: covert noncompliance with a primary enforcement law in Malaysia

Hauswald M

Accid Anal Prev, 1997 Sep;29(5):695-7.
PMID: 9316717

Malaysia has strict laws requiring seat belt use by all vehicle occupants. However, neither passive devices nor inertial reel belts are mandated. Seat belt usage was investigated among 60 taxicab drivers in Kuala Lumpur, Malaysia, in 1993. Although all drivers appeared to be restrained during an initial curb-side inspection, 60% did not fasten the latch. There was no statistical difference between ethnic groups. Curb-side estimates of restraint use may overestimate actual usage, resulting in falsely low estimates of effectiveness. Requiring inertial reel belts, which would retract if not latched, could greatly increase actual restraint use. This may be cost effective for developing nations.

Fulltext Investigation on motorcyclist riding behaviour at curve entry using instrumented motorcycle

Yuen CW, Karim MR, Saifizul A

ScientificWorldJournal, 2014;2014:968946.
PMID: 24523660 DOI: 10.1155/2014/968946

This paper details the study on the changes in riding behaviour, such as changes in speed as well as the brake force and throttle force applied, when motorcyclists ride over a curve section road using an instrumented motorcycle. In this study, an instrumented motorcycle equipped with various types of sensors, on-board cameras, and data loggers, was developed in order to collect the riding data on the study site. Results from the statistical analysis showed that riding characteristics, such as changes in speed, brake force, and throttle force applied, are influenced by the distance from the curve entry, riding experience, and travel mileage of the riders. A structural equation modeling was used to study the impact of these variables on the change of riding behaviour in curve entry section. Four regression equations are formed to study the relationship between four dependent variables, which are speed, throttle force, front brake force, and rear brake force applied with the independent variables.

THE LOSS OF MALAYSIA AIRLINES FLIGHT MH17: A FORENSIC AND HUMANITARIAN TASK

Ranson D

J Law Med, 2015 Jun;22(4):745-50.
PMID: 26349375

While forensic medical tasks are usually associated with supporting the criminal justice system, there are a range of forensic medical skills that can be brought to bear on addressing humanitarian activities. Disaster victim identification is a procedure that has achieved international standardisation through the work of a multinational Interpol Standing Committee. While part of a police organisation, it includes forensic pathologists, anthropologists, odontologists and molecular biologists who provide most of the specialist scientific input regarding identification that is integrated with police processes such as document examination and fingerprinting. The loss of Malaysian Airlines Flight MH17 represented a major activation of these procedures in an environment that had both humanitarian and forensic criminal investigation components. The information that is derived from the processes involved in disaster victim identification has a value that goes far beyond the determination of identity. It has an important humanitarian role in supporting the family and friends of the victims in their bereavement journey.

Fulltext [The risk of road traffic accidents among primary school children in Kuala Terengganu]

Fatimah M, Osman A

Med J Malaysia, 1997 Dec;52(4):402-8.
PMID: 10968118

A case control study was conducted in 1996 among primary school student in Terengganu. The objective of the study is to determine the relationship between road traffic accidents and factors such as socio-economic status, distance from school, number of siblings, behavioural problems, knowledge and attitudes of pupil and their parents towards road safety and parents' educational status. A total of 140 cases was obtained from 3 urban schools and 3 from rural schools. Cases were matched with control according to age sex and locality of residence. There were significant associations between road traffic accidents and pupils' knowledge regarding road crossing (OR = 0.40, 95% CI = 0.19-0.85), parental supervision (OR = 0.43, 95% CI = 0.19, 0.64) and parents having driving licences (OR = 0.99, 95% CI = 0.856-0.999). Road safety education for pupils and parental supervision are key measures in preventing road traffic accidents among primary school children.

Liam CK, How LG, Tan CT

Med J Malaysia, 1996 Mar;51(1):143-5.
PMID: 10967996

Three patients involved in road traffic accidents were suspected to have obstructive sleep apnoea (OSA). Two of them fell asleep while riding motorcycles and one patient fell asleep behind the wheel of a truck causing it to overturn. The diagnosis of OSA in each case was suspected based on a history of loud snoring, restless sleep, and excessive daytime somnolence and was confirmed by sleep studies.

Predictive model for motorcycle accidents at three-legged priority junctions

Harnen S, Umar RS, Wong SV, Wan Hashim WI

Traffic Inj Prev, 2003 Dec;4(4):363-9.
PMID: 14630586

In conjunction with a nationwide motorcycle safety program, the provision of exclusive motorcycle lanes has been implemented to overcome link-motorcycle accidents along trunk roads in Malaysia. However, not much work has been done to address accidents at junctions involving motorcycles. This article presents the development of predictive model for motorcycle accidents at three-legged major-minor priority junctions of urban roads in Malaysia. The generalized linear modeling technique was used to develop the model. The final model reveals that motorcycle accidents are proportional to the power of traffic flow. An increase in nonmotorcycle and motorcycle flows entering the junctions is associated with an increase in motorcycle accidents. Nonmotorcycle flow on major roads had the highest effect on the probability of motorcycle accidents. Approach speed, lane width, number of lanes, shoulder width, and land use were found to be significant in explaining motorcycle accidents at the three-legged major-minor priority junctions. These findings should enable traffic engineers to specifically design appropriate junction treatment criteria for nonexclusive motorcycle lane facilities.

Engaging policy makers in road safety research in Malaysia: a theoretical and contextual analysis

Tran NT, Hyder AA, Kulanthayan S, Singh S, Umar RS

Health Policy, 2009 Apr;90(1):58-65.
PMID: 18937995 DOI: 10.1016/j.healthpol.2008.08.009

Road traffic injuries (RTIs) are a growing public health problem that must be addressed through evidence-based interventions including policy-level changes such as the enactment of legislation to mandate specific behaviors and practices. Policy makers need to be engaged in road safety research to ensure that road safety policies are grounded in scientific evidence. This paper examines the strategies used to engage policy makers and other stakeholder groups and discusses the challenges that result from a multi-disciplinary, inter-sectoral collaboration. A framework for engaging policy makers in research was developed and applied to describe an example of collective road safety research in Malaysia. Key components of this framework include readiness, assessment, planning, implementation/evaluation, and policy development/sustainability. The case study of a collaborative intervention trial for the prevention of motorcycle crashes and deaths in Malaysia serves as a model for policy engagement by road safety and injury researchers. The analytic description of this research process in Malaysia demonstrates that the framework, through its five stages, can be used as a tool to guide the integration of needed research evidence into policy for road safety and injury prevention.

Ingested pins - A potential hazard for hijabis: A case report

Siti Soraya AR

Med J Malaysia, 2020 01;75(1):78-79.
PMID: 32008026

Accidental swallowing of objects commonly occurs among children and most of the objects pass through the gastrointestinal tract and out with the stool without any complications. However, recent reports have shown that there is an increasing occurrence of accidental ingestion of hijab pins among young hijab-wearing Muslim women or "hijabi". We highlight one such case, in which a young lady accidentally swallowed a pin that she was holding between her lips while she was styling her hijab. The pin was not successfully retrieved via endoscopy but was fortunately excreted spontaneously without any serious complications.

Fulltext A New Pedestrian Crossing Level of Service (PCLOS) Method for Promoting Safe Pedestrian Crossing in Urban Areas

Ahmed T, Moeinaddini M, Almoshaogeh M, Jamal A, Nawaz I, Alharbi F

Int J Environ Res Public Health, 2021 08 20;18(16).
PMID: 34444563 DOI: 10.3390/ijerph18168813

Crosswalks are critical locations in the urban transport network that need to be designed carefully as pedestrians are directly exposed to vehicular traffic. Although various methods are available to evaluate the level of service (LOS) at pedestrian crossings, pedestrian crossing facilities are frequently ignored in assessing crosswalk conditions. This study attempts to provide a comprehensive framework for evaluating crosswalks based on several essential indicators adopted from different guidelines. A new pedestrian crossing level of service (PCLOS) method is introduced in this research, with an aimto promote safe and sustainable operations at such locations. The new PCLOS employs an analytical point system to compare existing street crossing conditions to the guidelines' standards, taking into account the scores and coefficients of the indicators. The quantitative scores and coefficients of indicators are assigned based on field observations and respondent opinions. The method was tested to evaluate four pedestrian crosswalks in the city of Putrajaya, Malaysia. A total of 17 indicators were selected for the study after a comprehensive literature review. Survey results show that the provision of a zebra crossing was the most critical indicator at the pedestrian crossings, while drainage near crosswalks was regarded as the least important. Four indicators had a coefficient value above 4, indicating that these are very critical pedestrian crossing facilities and significantly impact the calculation of LOS for pedestrian crossings. Four crosswalks were evaluated using the proposed method in Putrajaya, Malaysia. The crosswalk at the Ministry of Domestic Trade Putrajaya got the "PCLOS A". In contrast, the midblock crossing in front of the Putrajaya Corporation was graded "PCLOS C". While the remaining two crosswalks were graded as "PCLOS B" crosswalks. Based on the assigned PCLOS grade, the proposed method could also assist in identifying current design and operation issues in existing pedestrian crossings and providing sound policy recommendations for improvements to ensure pedestrian safety.

Geospatial and clinical analyses on pediatric related road traffic injury in Malaysia

Rahman NH, Rainis R, Noor SH, Syed Mohamad SM

World J Emerg Med, 2016;7(3):213-20.
PMID: 27547282 DOI: 10.5847/wjem.j.1920-8642.2016.03.009

BACKGROUND: The main aim of this study is to utilize the geographical information system (GIS) software and perform the spatial analysis in relation to clinical data for road traffic injury (RTI) pediatric cases attending the emergency department.
METHODS: The study sample included pediatric patients (age less than 18 years) with road-related injuries within a district in Malaysia who attended emergency departments of two tertiary hospitals within the district. In addition to injury, pre-hospital care and outcome data, the coordinate of the locations were obtained by the ambulance paramedics by using portable handheld GPS unit brand Garmin(®) model GPS 72 H. The data was transferred into the excel format which in turn underwent GIS analysis by using ARCGIS(®) (by ESRI) software version 10.1 licensed to the study institution.
RESULTS: A total of 102 (24.8%) of all motor vehicle crash (MVC) victims involved the pediatric age group (age 18 years and below). The mean (SD) age of the pediatric victims was 14.30 years (SD 3.830). Male comprised of 68 (66.7%) of the cases. Motorcyclists [88 (88.0%)] were the most common type of victims involved. Interestingly, the majority of the severely injured victims [75 (73%)] sustained the RTI on roads with maximum speed limit of 60 km/hour. The mean (SD) length of hospital stay was 7.83 days (5.59).
CONCLUSION: The pediatric related road traffic injury in Malaysia causes significant health and social burden in the country. This study showed both important clinical and geographical factors that need to be taken into consideration for future preventive action.

Fulltext Enhanced weight-based clustering algorithm to provide reliable delivery for VANET safety applications

Bello Tambawal A, Md Noor R, Salleh R, Chembe C, Oche M

PLoS One, 2019;14(4):e0214664.
PMID: 30946766 DOI: 10.1371/journal.pone.0214664

A vehicular ad hoc network (VANET) is an emerging and promising wireless technology aimed to improve traffic safety and provide comfort to road users. However, the high mobility of vehicles and frequent topology changes pose a considerable challenge to the reliable delivery of safety applications. Clustering is one of the control techniques used in VANET to make the frequent topology changes less dynamic. Nevertheless, research has shown that most of the existing clustering algorithms focus on cluster head (CH) election with very few addressing other critical issues such as cluster formation and maintenance. This has led to unstable clusters which could affect the timely delivery of safety applications. In this study, enhanced weight-based clustering algorithm (EWCA) was developed to address these challenges. We considered any vehicle moving on the same road segment with the same road ID and within the transmission range of its neighbour to be suitable for the cluster formation process. This was attributed to the fact that all safety messages are expected to be shared among the vehicles within the vicinity irrespective of their relative speedto avoid any hazardous situation. To elect a CH, we identified some metrics on the basis of the vehicle mobility information. Each vehicle was associated with a predefined weight value based on its relevance. A vehicle with the highest weight value was elected as the primary cluster head (PCH). We also introduced a secondary cluster head (SeCH) as a backup to the PCH to improve the cluster stability. SeCH took over the leadership whenever the PCH was not suitable for continuing with the leadership. The simulation results of the proposed approach showed a better performance with an increase of approximately40%- 45% in the cluster stability when compared with the existing approaches. Similarly, cluster formation messages were significantly minimized, hence reducing the communication overhead to the system and improving the reliable delivery of the safety applications.
