“…In particular, a bivariate probit (BP) model was utilized in order to control the common unobserved factors that affect both the e-bike involved crash and license plate use. The BP model is an extension of the univariate binary probit and is designed to model binary dependent variables that may be simultaneously determined [22,[29][30][31]. If two separate univariate probit models were developed for each dependent variable, the correlation between the disturbances would be ignored, leading to inefficiency in model estimation [31].…”

The primary objective of this study is to evaluate factors affecting e-bike involved crash and license plate use in China. E-bike crashes data were collected from police database and completed through a telephone interview. Noncrash samples were collected by a questionnaire survey. A bivariate probit (BP) model was developed to simultaneously examine the significant factors associated with e-bike involved crash and e-bike license plate and to account for the correlations between them. Marginal effects for contributory factors were calculated to quantify their impacts on the outcomes. The results show that several contributory factors, including gender, age, education level, driver license, car in household, experiences in using e-bike, law compliance, and aggressive driving behaviors, are found to have significant impacts on both e-bike involved crash and license plate use. Moreover, type of e-bike, frequency of using e-bike, impulse behavior, degree of riding experience, and risk perception scale are found to be associated with e-bike involved crash. It is also found that e-bike involved crash and e-bike license plate use are strongly correlated and are negative in direction. The result enhanced our comprehension of the factors related to e-bike involved crash and e-bike license plate use.

Unfavorable temperature perception and/or thermal discomfort are frequently given arguments for not wearing a motorcycle helmet (Patel and Mohan, 1993;Skalkidou et al, 1999;Li et al, 2008b), which is supported by field observations (Gkritza, 2009). Generally, a substantial fraction of riders do not wear helmets, ranging, e.g., from 7.7% (ACEM, 2004) between 1999 and 2000 for European countries, 40 -8% for the USA from 1994 to 2006 (Glassbrenner and Ye, 2006), and 25% in Taiwan between 1999 and 2001 (Keng, 2005).…”

“…It is well established that the use of a motorcycle helmet increases the likelihood of surviving a motorcycle or moped traffic accident (Deutermann, 2004;Keng, 2005;Ouellet and Kasantikul, 2006;Houston and Richardson, 2008), motivating continual efforts to study their function (Tan and Fok, 2006;Comelli et al, 2008;Lai and Huang, 2008;Mills et al, 2009;Młyński et al, 2009) and use (Oginni et al, 2007;Houston and Richardson, 2008;Li et al, 2008a;Mayrose, 2008;Gkritza, 2009). Motorcycle helmets are required to cover more of the head than most protective helmets, and those offering the most protection, full-face helmets, greatly reduce the interaction of the wearer with his/her environment.…”

“…Inconsistency in these results may be due to influence of road type on whether motorcyclists considered helmet use necessary, as well as variation of enforcement across different road types. Observational roadside studies have shown that motorcyclists are more likely to use helmets in winter, weekdays and early morning hours (ZamaniAlavijeh et al, 2011;Li et al, 2008;Skalkidou et al, 1999;Conrad et al, 1996;Gkritza, 2009), but have not revealed why these factors affect helmet use, or whether these factors are causal.…”

Sixty percent of motorcyclist fatalities in traffic accidents of Iran are due to head injuries, but helmet use is low, despite it being a legal requirement. This study used face-to-face interviews to investigate the factors associated with helmet use among motorcycle riders in Mashhad city, the second largest city in Iran. Principal component analysis (PCA) and confirmatory factor analysis (CFA) were used for data reduction and identification of consistent features of the data. Ordered and multinomial logit analyses were used to quantify the influences on helmet use and non-use. The data show that 47% of the sample used a helmet, but a substantial proportion of these did not wear their helmet properly. In addition, 5% of motorcyclists believed that helmets reduced their safety. Norms, attitudes toward helmet use, risky traffic behavior and awareness of traffic rules were found to be the key determinants of helmet use, but perceptions of enforcement lacked influence. Duration of daily motorcycle trips, riding experience and type of job also affected helmet use. Results indicate that motorcyclist training, safety courses for offending motorcyclists and social programs to improve social norms and attitudes regarding helmet use are warranted, as are more effective law enforcement techniques, in order to increase proper use of helmets in Iranian motorcyclists. In addition, special safety courses should be considered for motorcyclists who have committed traffic violations.
