“…Measures such as effectively targeted inspections and effective compliance with the legislation, 5,12,24 improving roads, proper road signs and street lighting 12 and investment in safety devices for motorcycle users, 20 in addition to helmets are some initiatives which may minimize these findings. The need for integrated actions must be emphasized, and that road safety should become a national priority, as indicated in a recent document.…”

OBjeCTIve: To compare the characteristics of motorcycle accidents and victims attended by pre-hospital care services. MeTHOdS:A cross-sectional study was carried out using data on pre-hospital care of motorcyclists who had been injured in traffic accidents in Londrina, PR, Southeastern Brazil, in 2010, whose results were compared with those of a similar study conducted in 1998. Paramedic assistance registration forms were used as source of data. The fleets of motorcycles and the population of both years were used for estimating risks of accidents occurring. The Chi-square test was used to compare the profiles of accidents and victims.ReSuLTS: In 1998 and in 2010, respectively, 1,576 and 3,968 motorcyclists were seen (increase of 151.8%). The rate of injured motorcyclists per 1,000 inhabitants rose from 396.4 to 783.1, and that of the victims per 1,000 motorcycles from 53.1 to 61.1. Changes (p < 0.05) in the profile of accidents were observed, with higher proportions of falls from motorcycles, accidents between motorcyclists and occurrence during mornings, and a reduction of those at weekends. Regarding the victims, higher proportions of women, drivers, and those aged 35 years or over were observed. There was a decrease in the relative frequency of positive breathalyser results and an increase in the prevalence of helmet use. A lower proportion of victims were classified with moderate/severe coma and trauma scores and sent to hospitals. The immediate fatality rate dropped from 1.2% to 0.6%. COnCLuSIOnS:Changes in the profiles of accidents and victims were observed in the period. Despite an absolute and relative increase in the number of victims of motorcycle accidents, a proportionally lower severity of these accidents was observed.

“…were less likely to be at-fault during crashes that occurred at night time or at 54 locations where surveillance cameras were present (Haque et al 2009). Younger 55 motorcyclists are more likely to be at-fault in the event of a collision, as are riders 56 who are under the influence of alcohol (Seiniger et al 2012). 57…”

6Powered two wheeler (PTW) riders are a group of vulnerable road users that are 7 overrepresented compared to other road user groups with regards to crash injury 8 outcomes. The understanding of the dynamics that occur before a crash benefits in 9 providing suitable countermeasures for said crashes. A clearer interpretation of 10 which factors interact to cause collisions allows an understanding of the mechanisms 11 that produce higher risk in specific situations in the roadway. 12Real world in-depth crash data provides detailed data which includes human, 13 vehicular and environmental factors collected on site for crash analysis purposes. 14 This study used macroscopic on-scene crash data collected in the UK between the 15 years 2000 -2010 as part of the "Road Accident In-depth Study" to analyse the 16 factors that were prevalent in 428 powered two-wheeler crashes. 17A descriptive analysis and latent class cluster analysis was performed to identify the 18 interaction between different crash factors and develop PTW scenarios based on this 19 analysis. multiple vehicle crashes. Results identified seven specific scenarios, the main types 21 of which identified two particular 'looked but failed to see' crashes and two types of 22 single vehicle PTW crashes. In cases where the PTW lost control diagnosis failures 23 were more common, for road users other than the PTW rider detection issues were 24 of particular relevance. 25 Keywords 26Powered two-wheelers, Human behavior, Human functional failure, Crash causation 27

“…At higher speed, gyroscopic effects allow the motorcycle to follow a path and play an important role in balancing the vehicle [23]. From a theoretical point of view, stability of a motorcycle is defined by the fact that the available friction is higher than the lateral acceleration [11,21]. In fact motorcycle tyres are the main component that generate friction between the road surface and the tyres and transfer the forces to the road surface.…”

“…Many previous studies have focused on stability under cornering condition by using simulation or modeling approach [14][15][16]. Recently attention was paid to the development of active control systems such as Advanced Rider Assistance Systems (ARAS) [17][18][19][20] Anti-Lock Braking System (ABS) and Traction Control Systems (TCS) using experimental approach [21]. The vehicles used in these studies were normally high performance motorcycles with engine capacity greater than 250 cc.…”

Abstract. The objective of this study is to investigate the stability of lightweight motorcycle in straight path running test. The stability of three different tyre dimensions was measured using acceleration, angular velocity and vehicle speed signals from smartphone sensors. The signals were analysed to determine whether standard configuration of tyres used in lightweight motorcycles in various developing countries are safe in terms of vehicle stability. In order to identify effects of tyre width on driving stability, forward speed, angular acceleration and rotational velocity were measured. These measurements are valuable empirical data in the understanding of motorcycle balance mechanism. Results of analysis show that for the range of tyre width 70 mm to 110 mm for the front and 80 mm to 120 mm for the rear wheel used in the test, motorcycle stability is not affected by the tyre width for the straight path run with maximum speed of 60 km/h.
