    This paper presents the approach taken by the Malaysian Government to contain motorcycle casualties in Malaysia. It involves the exposure control, crash prevention, behaviour modification and injury control related to humans, vehicles and the environment based on pre-crash, crash and post-crash scenarios of motorcycle accidents. These initiatives emanated mainly from the research and development carried out by the Road Safety Research Centre at Universiti Putra Malaysia. Recent outcomes from these initiatives are presented and their impact is highlighted.

    Motorcyclists form the highest group of fatalities on Malaysian roads. This is a prospective study conducted at 3 major hospitals for a period of 12 months to determine the type of motorcyclist injuries that usually required hospitalization. Four hundred and twelve consecutively injured motorcyclists were available for study. One hundred and eighty six (45.15%) were fatally injured and 226 (54.85%) were seriously injured and surviving. The main cause of fatalities was head injury, while lower limb injuries accounted for majority of hospitalizations. This study highlights the vulnerability of the motorcyclist to lower limb injuries.

    In developing countries, motorcycle use has grown in popularity in the past decades. Commensurate with this growth is the increase in death and casualties among motorcyclists in these countries. One of the strategic programs to minimize this problem is to reduce motorcyclists exposure by shifting them into safer modes of transport. This study aims to explore the differences in the characteristics of bus and motorcycle users. It identifies the factors contributing to their choice of transport mode and estimates the probability that motorcyclists might change their travel mode to a safer alternative; namely, bus travel.

    Motorcyclists constitute a large proportion of total road casualties in Asian countries Unfortunately, studies conducted for the purpose of evaluating the cost of traffic crashes, and cost-benefit analyses of safety interventions, are almost nonexistent in these countries. The loss-of-output approach to valuing life has been used for many years, yet this method has also long been criticised as it results in significant resource misallocation. This study attempts to overcome this problem by estimating the value of a statistical life among motorcyclists using the willingness-to-pay method that is commonly used in developed countries. The study recommends adopting a value of MYR1.1 million (almost five times the previous estimate) per statistical life for public policy analysis involving motorcycle safety.

    Cervical spine injuries such as subluxation and fracture dislocation have long been known to result in severe consequences, as well as the trauma management itself. The injury to the region has been identified as one of the major causes of death in Malaysian motorcyclists involved in road crashes, besides head and chest injuries (Pang, 1999). Despite this, cervical spine injury in motorcyclists is not a well-studied injury, unlike the whiplash injury in motorcar accidents. The present study is a retrospective study on the mechanisms of injury in cervical spine sustained by Malaysian motorcyclists, who were involved in road crash using an established mechanistic classification system. This will serve as an initial step to look at the cervical injuries pattern. The information obtained gives engineer ideas to facilitate design and safety features to reduce injuries. All cervical spine injured motorcyclists admitted to Hospital Kuala Lumpur between January 1, 2000 and December 31, 2001 were included in the present study. Based on the medical notes and radiological investigations (X-rays, CT and MRI scans), the mechanisms of injuries were formulated using the injury mechanics classification. The result shows that flexion of the cervical vertebrae is the most common vertebral kinematics in causing injury to motorcyclists. This indicates that the cervical vertebrae sustained a high-energy loading at flexion movement in road crash, and exceeded its tolerance level. The high frequency of injury at the C5 vertebra, C6 vertebra and C5-C6 intervertebral space are recorded. Classification based on the Abbreviated Injury Scale (AIS) is made to give a view on injury severity, 9.1% of the study samples have been classified as AIS code 1, 51.5% with AIS 2 and 21.2% with AIS 3.

    Lower limb injuries are the main cause of temporary and permanent disability among motorcyclists in Malaysia. They cause non-fatal but serious injuries requiring hospitalisation. Detailed studies on factors influencing lower limb injuries are justified in an attempt to reduce the occurrence of these injuries. This study presents a computer simulation of the crash behaviour of the basket of a small-engined motorcycle with the lower limb using finite element (FE) methods. The results suggest that the extensive deformation of the motorcycle basket may reduce the risk of injury to the lower limb. The behaviour of the basket during collision is analogous to the crumple zone of automobiles.

    This study examines the accident characteristics of injured motorcyclists in Malaysia. The aim of this study is to identify the characteristics of motorcyclists who are at higher fatality risk and subsequently be the targeted group for the fatality-reduction countermeasures. A total of 412 motorcycle crash victims with serious or fatal injuries were analysed. The results showed that the injured motorcyclists were predominant young, novice riders of less than 3 years licensure and male. A fatal outcome was more likely to be associated with a larger engine capacity motorcycle, collision with a heavy vehicle, head on collision, and collision at a non-junction road. In contrast, a non-fatal outcome was more likely to be associated with a small engine capacity motorcycle, collision with another motorcycle or passenger car, junction accidents, and side or rear collisions.
