IJCM_246A: Estimating the prevalence of seat belt usage in motor cars: A descriptive cross-sectional study in Mangalore

Background: Every year 1.25 million people die of road traffic accidents. Several safety measures can be taken to prevent RTAs. The SDG 2030 set the target to halve the number of global death and injuries from road traffic accidents by the year 2020. The aim of this study is to estimate the prevalence of seat belt use and factors influencing it including driver characteristics, type of car and time of day and distractions while driving. Methodology: This Descriptive cross-sectional study was set on the major roads and intersections of Mangalore, recruiting the drivers and front-seat passengers in the motor cars at the time and site of observation. Results: A total of 6165 motor cars were observed. 15 (0.2%) of these cars had completely tinted car windows, therefore out of the total, 6150 motor cars could be properly observed. 70.91% (4361) of drivers were wearing seat belts. Seat belt usage among drivers was found to be higher on highways (76.6%) as compared to on residential and city roads (69.3%). In vicinity of traffic police, 76.5% of drivers were observed to be wearing seat belts in contrary only 67.8% of them were wearing seatbelts in the absence of traffic police. Prevalence of mobile phone use and other distractions amongst drivers was 2.1%. Out of 2646 adult front seat passengers observed, only 10.9% were wearing seat belts. Conclusion: Among drivers, type of motor car, traffic zone and type of road and presence of traffic police in vicinity are significantly associated factors with seatbelt usage. Among adult front seat passengers, type of motor car, traffic zone, type of road and presence of traffic police in vicinity are significantly associated. Among front seat child passengers, type of road and traffic zone are significantly associated with seat belt usage.

Mobile phone use by young children and parent's views on children's mobile phone usage.

This study aims to explore the prevalence of mobile phone use among young children aged 6 months to 4 years. We studied the usage patterns, optimal age for use, and the attitudes of parents toward their child's mobile phone use. We conducted a cross-sectional study in a pediatric OPD of a tertiary teaching hospital for a period of 2-months. Ethics committee approval and informed consent was taken before conducting the research. A predesigned and validated questionnaire was used to collect data. We calculated a sample size of 90 children at a 95% confidence level. Chi-square test and Fischer's exact test were used as a test of significance at 5% level of significance. We observed that 73.34% of children were using mobile phones and mobile phone usage increased with age. Children used mobile phones for educational purposes (43.9%), and for less than an hour a day (57.6%). In the 3-4 year age group, 19% used mobile phones for 3 hours or more. While 93.3% of parents felt they shouldn't give their child a phone, 71.4% children of these parents still used one. Our study highlights a high prevalence of mobile phone use among young children aged 6 months to 4 years. Although parents aimed to limit their child's phone usage, the reality was different. We recommend that guidelines on mobile phone use be followed in India.

A Study on Mobile Phone Addiction Among B.Ed Teacher Trainees of University of Mysore

Mobile phone has become an integral part of our daily living the problem of mobile phone addiction is growing across the world especially among adults. Such devices may negatively affect their mental health and well-being. Rapid development in mobile phone technologies provides a rich selection of features and improved portability that increases the prevalence of mobile phone use, especially young adults. The present study was conducted on sample of 104 B.Ed. teacher trainees and mobile phone addiction standardized scale by Dr. Velayudhan and Dr. S Srividya was used for data collection. The analysis of data revealed that there is no significant difference between rural and urban B.Ed. teacher trainees with respect to their mobile phone addiction as well as streams of study i.e., arts and science, whereas significant difference was found between male and female B.Ed. teacher trainees with respect to their mobile phone addiction.

Key factors associated with parents’ illegal engagement with their smartphones while driving their children

This study aimed to examine the key factors associated with parents’ and caregivers’ illegal engagement with their smartphones while driving with their children aged 10 years and younger. Five hundred and ten participants completed an online survey (M = 40.4 years, SD = 6.9, Range = 20.0–69.0 years; Female: 79.2%). Most participants reported that they ‘never’ accessed social media, talked or composed a text on their smartphone (while handheld) while driving with their children (88.0%, 85.3%, and 80.0%, respectively). However, it was interesting to note that more than one-quarter of the sample reported that they had read a text message or used an app on their handheld smartphone while driving their children (36.3%, and 28.6%, respectively). The results of a logistic regression model showed that participants': age, severity of nomophobia (the fear of being without a mobile phone), and self-reported engagement in other risky driving behaviours (i.e., errors, violations) were significantly associated with illegal engagement with their smartphone while driving their child aged 10 years and younger. With the growing prevalence of mobile phone use and the impact of distraction due to child occupants, it is important to consider the compounded effect of these factors on driver performance, as well as the influence of driver risk-taking behaviour while engaging with smartphones and the consequences of this on children who observe this behaviour.

The prediction of Nomophobia Based on Perceived Parenting Styles with Mediating Role of Loneliness

Background and Aim: Considering the prevalence of mobile phone use and more dependence on it, it is necessary to know the factors affecting it, The purpose of this study was to study prediction of nomophobia based on perceived parenting styles with mediating role of loneliness. Research method: This research was a descriptive study of structural equation modeling. This study was conducted in the presence of 500 student by available sampling method among students Kashan city in year academic 1400-1401. To measure the variables, nomophobia questionnaire of Yildirim and Correia (2015), parnetal styles questionnaire of Naghashian (2006) and short form of the social and emotional loneliness scale for adults of DiTommaso and et al (2004) were used. Data were analyzed using Pearson correlation and structural equation modelling with using SPSS-24 and AMOS software was investigated. Results: The results showed that there is a positive and significant relationship between perceived parenting and loneliness with nomophobia (P <0.01). The results also showed that most of the direct paths of this study were significant and the indirect paths of perceived parenting styles were significant through the mediating role of loneliness on nomophobia. Conclusion: proposed model had an acceptable fitness to the data (RMSEA=0/062, P-value<0/05) and evaluated model has a good fit and is an important step in identifying the factors that are effective in nomophobia in students.

Hence, this paper emphasizes the necessity of proper use of technology and provides direction to the technology-savvy youth in particular on how to reap the technology's advantage for their positive growth. This paper presents an integrative conceptual framework, and a detailed summary for each topic. This study identifies three psychological characteristics namely self-esteem, social extraversion and anxiety that derived towards the mobile phone use and will be impact to the long term on mobile phone addiction. An integrative conceptual framework and a detailed summary table are presented in this paper. This paper demonstrates a model on relationship between psychological characteristic, use of mobile phones and mobile phone addiction among youths.

Mobile phone use and trends in the incidence of cancers of the parotid and other salivary glands

BackgroundThere has been a significant increase in the use of mobile phones over the last three decades and a possible association with head cancers has been suggested, including cancers of the parotic and other salivary glands. We examined the incidence time trends of parotid and other salivary gland cancers in Australia to ascertain the influence of increased mobile phone use. MethodsAnalyses of incidence time trends were carried out using Poisson regression to estimate the annual percentage change (APC) in the incidence of salivary gland cancers of all available national registration data from 1982 to 2016, as well as specific time periods (1982−1993, 1994−2005, 2006−2016) representing changes in the prevalence of mobile phone use. ResultsThe incidence of parotid gland cancer was stable for the periods 1982−1993 and 1994−2005. During 2006−2016 there was a large decrease in parotid gland cancer for males (APC: -3.71, 95 %CI: -6.66 to -0.67) and a large increase in females (4.80, 1.77–7.91) for adults aged 20−59 years. The incidence for other salivary gland cancers was stable during all the periods. ConclusionsThe results do not indicate that mobile phone use increased the incidence of parotid or other salivary gland cancers. An increase in parotid gland cancer in females since 2006 may be attributed to other possible risk factors specific to this gender.

Prevalence of use of mobile phones while driving in Italy: results of a multicentric observational study

to provide an overview of the use of mobile phone in Italy while driving in the years 2015-2017. road side observational study. a sample of 145.107 drivers in 28 cities across the national territory with a resident population of more than 10 million inhabitants (17% of the Italian population). For each city, the survey was carried out in Urban (U), Sub-Urban (SU), and Extra-Urban (EXT) areas. Data were aggregated by three geographic areas: North, Centre and South. monitoring of the use of mobile phone when driving. the prevalence of mobile phone use when driving is 5.6% in the North, 4.1% in the Centre, and 6.3% in the South. The stratification by urban area also shows similar values (U: 5.3%; SU: 5.1%; EXT: 7.4%). a considerable prevalence of use of mobile phone when driving is observable throughout Italy, with substantially homogeneous values in different territories and in areas with different levels of urbanization. This behaviour increases the risk of road traffic accidents, according to scientific literature. Despite normative sanction of this behaviour, the prevalence is still high, even though comparable to what observed in other industrialized countries. Multilevel actions could be implemented, effective according to scientific literature, not limited only to the regulatory-sanctioning ones. The reduction of the use of the mobile phone while driving can have a significant impact for public health and traffic safety, because on the prevalence data of this study it is possible to assess that potentially up to 24,000 accidents/year could be avoided in Italy.

Mobile Phone Use and Acceptability for the Delivery of Mental Health Information Among Perinatal Adolescents in Nigeria: Survey Study.

BackgroundThere are several barriers that may hamper adolescent mothers’ utilization of available health interventions for perinatal depression. Innovative treatment approaches are needed to increase adolescent mothers’ access to mental health care for improved maternal and child health outcomes. Mobile phones have the potential to serve as important conduits to mental health care in Africa. However, mobile phone use patterns and needs among young mothers in Nigeria are not well documented.ObjectiveThis study sought to determine the prevalence of mobile phone use among perinatal adolescents and report patterns of use, as well as to assess the openness of young mothers to mobile health (mHealth) mental health interventions.MethodsWe surveyed 260 adolescent mothers (ages 16-19 years) in their perinatal or postnatal periods of pregnancies in 33 primary health care clinics in Ibadan, Oyo State, Nigeria in 2020. Respondents were included if they were pregnant with a gestation age of greater than or equal to 4 weeks, or had babies (which they had birthed) that were younger than 12 months.ResultsThe total study sample consisted of 260 adolescent mothers with a mean age of 18.4 (SD 0.88) years. The majority of the respondents (233/260, 89.6%) owned mobile phones (eg, keypad, keypad and internet, smartphones); 22 (8.5%) of the 260 mothers had access to phones that belonged to relatives who lived in the same household, while 5 (1.9%) had access only to public paid phones. Only 23% (54/233) of phone owners (which is 20.5% of the total study population) had smartphones. On average, respondents reported first using mobile phones at 15.5 (SD 2.06) years old. The majority of respondents (222/260, 85.4%) reported using their phones for an average of 45 minutes daily for calls to family members. Facebook was the social media platform that was most often used among respondents who had phones with internet access (122/146 minutes per day, 83.4%). The majority of the sample responded as being “interested” and “very interested” in the use of mobile phones for preventive interventions (250/260, 96.2%) and treatment (243/260, 93.5%) information on mental illness such as depression and “hearing voices.” Half of the respondents (126/233, 50.4%) preferred to receive such information in the form of text messages.ConclusionsFindings from this study suggest that the vast majority of perinatal adolescents in Nigeria own and use mobile phones and that they are interested in leveraging these devices for prevention, treatment, and informational campaigns focused on mental health. The use of smartphones in this population is relatively low, and health intervention through text messages were favored by the women.

The Role of Social Networks in Mobile Phone Use among Pedestrians: A Pilot Study in China

Pedestrian safety is alarming worldwide, and it is well validated that distracted walking/crossing involving mobile phone use would significantly compromise pedestrian safety. Some existing studies demonstrated that distracted pedestrians would spend more time to cross street, miss more safe opportunities to cross and pay less attention to the road environment, etc. As a result, they are more likely to be hit by an oncoming vehicle. Specifically, with respect to the distraction results from mobile phone use for communication in road user groups, previous research has examined the relationship between social networks and mobile phone use among drivers and motorcyclists. However, very little similar research was found in the field of pedestrian study. This study performed an online survey to investigate with whom pedestrians were most likely to communicate with while crossing street in a Chinese sample. The association between social networks and self-reported injury/ near miss event was also examined. To provide an insight into the difference in communication pattern between scenarios, the results were compared with the patterns while driving, motorcycling and the general patterns. Results indicate that pedestrians are most likely to communicate with friends (31.2%), followed by spouses (24.5%). Additionally, participants who frequently talk to parents/children have a greater likelihood of being involved in injury/ near miss events than those talk to the others. Compared with the prevalence of mobile phone use among drivers and motorcyclists reported in previous studies, mobile phone use is more prevalent among pedestrians, especially as they are more likely to communicate with colleagues. In sum, the results demonstrate that social networks play an important role in mobile phone use during street crossing, and pedestrians are more likely to communicate with people who are socially closest to them. The effect of social networks on mobile phone use (especially for communication) among pedestrians should be considered in the development of traffic safety countermeasures.

Mobile phone use while driving: Prevalence, task management strategies, risk perception and attitude among Qassim University students.

Background:Globally, motor vehicle accidents (MVAs) cause around 1.35 million deaths annually. Distracted driving, a risk factor for MVA, includes diversion of attention from driving because of use of mobile phone.Objectives:The aim of this study was to determine prevalence of mobile phone use and to explore task management strategies, risk perception and attitude towards mobile phone use while driving among Qassim University students.Methods:An online cross-sectional survey among 212 randomly selected medical (n = 83) and engineering students (n = 129) of Qassim University, Saudi Arabia, through semi-structured, self-administered questionnaire, designed using Google forms. The survey was conducted from February to March 2020.Results:The overall prevalence of mobile phone use while driving was 93.4% (medical students: 96.4%; engineering students: 91.5%). Around 49.5% participants 'often' or 'always' used mobile phone while driving. Among task management strategies, 169 (79.7%) participants were 'likely' or 'very likely' to lower their driving speed while 90 (42.5%) were 'likely' or 'very likely' to increase control over the steering while using mobile phone during driving. Regarding risk perception, 173 (81.6%) participants thought that they were 'unlikely' or 'very unlikely' to have MVA on looking at phone continuously for more than 2 s, and 185 (87.3%) participants thought that they were 'unlikely' or 'very unlikely' to have MVA by texting or browsing while driving. Thirty-six (17%) participants reported MVA because of distraction by mobile phone use while driving.Conclusion:High prevalence of mobile phone use during driving and low perceived risk of experiencing MVA because of mobile phone use was found among Qassim University students. Creating awareness on risks of mobile phone use while driving is recommended.

The Prevalence of Mobile Phone Use in The School Going Children in North Al Batinah Region of Oman: A Cross Sectional Study

The use of mobile phones has become increasingly common among general population, but how much has it increased among the young school going population remains to be seen.Our objective was to investigate the prevalence of mobile phone use, during and after school hours, and its ownership in the primary and secondary section students in Oman.We surveyed 414 students in Cycle 1 and 1438 students in Cycle 2 in the city of Sohar, North Al Batinah region of Oman. Students completed a paper-based questionnaire about mobile phone use, the apps they use and whether their parents keep a check on their cell phone use. 86% of primary section students reported using a mobile phone whereas 91% of students in secondary section reported use of mobile phone. Most popular mobile use among the primary section students were playing games on mobile phones whereas, secondary section students mostly used their phones to access internet. 86.7% of primary section students said that their parents were aware of how they used their mobile phones compared to 83.4% students in secondary section. Smart phone ownership and its use in school going students in Oman have increased from the past and is now almost the same in the students of primary and secondary sections. Students now start using mobile at a much younger age;however, the parents are well aware of the contents on their children’s mobile devices and sometimes even take away their mobile phone as punishment.

Mobile phone use among Indonesian motorcyclists: prevalence and influencing factors

Objective Indonesia is one of many developing countries that relies on motorcycles as a major mode of transportation. Unfortunately, the widespread use of motorcycles in Indonesia coincides with a high number of motorcycle accidents which can often be attributed to unsafe behaviors of the motorcyclist. One unsafe behavior that is common and hypothetically associated with accidents is the use of a mobile phone while motorcycling. The aim of the present study was to observe the prevalence and behavior of mobile phone use among Indonesian motorcyclists and the factors that might have influenced their behavior. Methods Five hundred Indonesian motorcyclists voluntarily participated in this study by filling out a questionnaire that gathered demographic data, motorcycling behaviors, and a statement related to what factors might influence their likelihood to use a mobile phone while motorcycling. A descriptive statistic and Structural Equation Modeling were applied in analyzing the data. Results Results showed that the prevalence of mobile phone use among Indonesian motorcyclists was 75%. The demographic data that significantly influenced mobile phone use during motorcycling were age, education level, marital status, and number of children. Occupation, gender, and prior experiences that included accidents and tickets with fines did not influence the use of mobile phones during motorcycling. The behavioral model showed that the factors that influenced motorcyclist's intentions to avoid mobile phone use during motorcycling were attitude, perceived behavioral control, and cues to action. Conclusions This study supports previous findings regarding the high prevalence of mobile phone use among motorcyclists in developing countries. The models implied that further investigation on intervention strategy to minimize mobile phone use during motorcycling is a necessity.

Prevalence of mobile phone use among drivers: direct observation in Udine (Northern Italy)

to measure the prevalence of hand-held mobile phone use among drivers in Udine, Italy. Such behaviour is prohibited by law. direct roadside observation of car drivers. groups of nursing students on the roadside observed car drivers either waiting at red traffic lights or driving in selected major urban streets of the city of Udine and of two smaller neighboring towns, in one-hour time slots in different days in November and December 2018, for a total of 24 hours of observation. prevalence of use of handheld mobile phone either for calling or for activities implying visuo-manual interaction (texting or social media browsing), both among drivers waiting at red traffic lights and among those driving along the streets. overall, 8,240 observations of vehicles were carried out. The prevalence of mobile phone use was 9.9% among drivers waiting at red traffic lights and 6.5% among those moving along the streets in Udine; the prevalence was higher in the smaller neighboring towns. Among 6,116 drivers, the type of use has also been recorded: prevalence of texting was 7.2% at traffic lights and 5.0% in moving vehicles; prevalence of phone calls was 3.3% and 3.6%, respectively. Texting represented 68.4% of mobile phone use among drivers waiting at traffic lights and 57.8% among moving drivers. Behaviors of female and male drivers were similar. the use of mobile phones among drivers is very common in Udine, particularly for activities involving both the hands and the eyes. Since the increased risk of road accidents caused by this type of distraction from driving activities is well known, interventions discouraging the use of mobile phones among drivers are needed.

Unmatchability of mobile phone and handlebar: Predictors among professional motorcyclists at Cotonou (Benin)

In Benin, professional motorcyclists represent a consistent part of transport services, particularly in the city of Cotonou. However, this activity remains poorly regulated, which contributes to the development of risky behaviors. Among these latter, there is not enough evidence about the use of mobile phones while driving. The study aims to estimate the prevalence of mobile phone use while driving and to identify the associated factors among professional motorcyclists in Cotonou. It was a cross-sectional study involving 430 registered professional motorcyclists at parking lots in Cotonou in 2019. Univariate and multivariate analysis by the logistic regression model was used to identify factors associated with mobile use while driving. The prevalence of mobile phone use while driving was 12.47%. Multivariate revealed that factors associated with mobile phone use during driving among professional motorcyclists were alcohol consumption (AOR=2.10; 95% CI: [1.15-3.83]) and service length less than 10 years (AOR=2.20; 95%CI: [1.15-4.71]). Given the place of professional motorcyclists in public transport system and the hazard for consumers, use of mobile while riding should necessarily be addressed through road safety interventions and law enforcement. Faced with conjunction of risk behavior among this population, the findings highlighted also the needs of integrative approach in interventions towards professional motorcyclists. Key words: Mobile phone, risk factors, road traffic accident, Benin

Mobile phone related crashes among motorcycle taxi drivers

In many countries, motorcycle taxis remain an important mode of travel due to their fast, flexible, and inexpensive service. The recent advent of ride-hailing services has led to dramatic growth in the fleet of motorcycle taxis and additional types of motorcycle taxi drivers. Furthermore, mobile phone use while riding a motorcycle is an emerging safety issue, particularly among ride-hailing motorcycle taxi drivers. This paper investigates mobile phone use while riding, crashes and mobile phone related crashes among ride-hailing, traditional, and hybrid motorcycle taxi drivers, using data from a survey in Hanoi, Vietnam. Results show that ride-hailing motorcycle taxi drivers had the highest prevalence of mobile phone use while riding a motorcycle taxi (95.3%), followed by hybrid (88.6%) and traditional taxi drivers (64%). Approximately 32.6%, 19.3%, and 9.7% of motorcycle taxi drivers reported being involved in a crash, injury crash, and mobile phone related crash respectively. Mobile phone related crashes represent 20.5% of all reported crashes. Logistic and negative binomial regression were used to explore factors influencing mobile phone use while riding and crash frequencies. Regression results indicate that ride-hailing taxi drivers were more likely to be involved in a mobile phone related crash. Delivery trips were found to be associated with increases in crashes whereas passenger trips were found to be associated with decreases in crashes. Policy implications are also discussed.

Measurement Invariance of the Short Version of the Problematic Mobile Phone Use Questionnaire (PMPUQ-SV) across Eight Languages.

The prevalence of mobile phone use across the world has increased greatly over the past two decades. Problematic Mobile Phone Use (PMPU) has been studied in relation to public health and comprises various behaviours, including dangerous, prohibited, and dependent use. These types of problematic mobile phone behaviours are typically assessed with the short version of the Problematic Mobile Phone Use Questionnaire (PMPUQ–SV). However, to date, no study has ever examined the degree to which the PMPU scale assesses the same construct across different languages. The aims of the present study were to (i) determine an optimal factor structure for the PMPUQ–SV among university populations using eight versions of the scale (i.e., French, German, Hungarian, English, Finnish, Italian, Polish, and Spanish); and (ii) simultaneously examine the measurement invariance (MI) of the PMPUQ–SV across all languages. The whole study sample comprised 3038 participants. Descriptive statistics, correlations, and Cronbach’s alpha coefficients were extracted from the demographic and PMPUQ-SV items. Individual and multigroup confirmatory factor analyses alongside MI analyses were conducted. Results showed a similar pattern of PMPU across the translated scales. A three-factor model of the PMPUQ-SV fitted the data well and presented with good psychometric properties. Six languages were validated independently, and five were compared via measurement invariance for future cross-cultural comparisons. The present paper contributes to the assessment of problematic mobile phone use because it is the first study to provide a cross-cultural psychometric analysis of the PMPUQ-SV.

Calling, texting, and searching for information while riding a motorcycle: A study of university students in Vietnam

ABSTRACTObjective: The objective of this study was to investigate the prevalence of calling, texting, and searching for information while riding a motorcycle among university students and the influences of sociodemographic characteristics, social norms, and risk perceptions on these behaviors.Methods: Students at 2 university campuses in Hanoi and Ho Chi Minh City, the 2 largest cities in Vietnam, were invited to participate in an anonymous online survey. Data collection was conducted during March and May 2016.Results: There were 741 respondents, of whom nearly 90% of students (665) were motorcycle riders. Overall prevalence of mobile phone use while riding is 80.9% (95% confidence interval [CI], 77.9–83.9%) with calling having a higher level of prevalence than texting or searching for information while riding: 74% (95% CI, 70.7–77.3%) vs. 51.7% (95% CI, 47.9–55.5%) and 49.9% (95% CI, 46.1–53.7%), respectively. Random parameter ordered probit modeling results indicate that mobile phone use while riding is associated with gender, motorcycle license duration, perceived crash risk, perceived risk of mobile phone snatching, and perceptions of friends' mobile phone use while riding.Conclusions: Mobile phone use while riding a motorcycle is highly prevalent among university students. Educational programs should focus on the crash and economic risk of all types of mobile phone use while riding, including calling, texting, and searching for information. In addition, they should consider targeting the influence of social norms and peers on mobile phone use while riding.

Psychological predictors of mobile phone use while crossing the street among college students: An application of the theory of planned behavior

ABSTRACTObjective: As the prevalence of mobile phone use has increased globally, experts have verified the effects of mobile phone distraction on traffic safety. However, the psychological factors underlying pedestrians' decisions to use their mobile phones while crossing the street have received little attention.Methods: The present study employed the theory of planned behavior (TPB) to investigate the psychological factors that influence pedestrians' intentions to use a mobile phone while crossing the street. The additional predictors of descriptive norms, moral norms, risk perception, mobile phone involvement, and perceived ability to compensate are included.Results: Approximately 40% of participants reported having used a mobile phone while crossing during the previous week and 5.4% had been involved in crossing accidents due to mobile phone distractions. Hierarchical multiple regression analyses revealed overall support for the predictive utility of the TPB. The standard TPB variables accounted for 13.3% of variance in intentions after demographic variables were controlled, and the extended predictors contributed an additional 7.6% beyond the standard constructs.Conclusion: The current study revealed that attitude, perceived behavior control, descriptive norms, mobile phone involvement, and perceived ability to compensate all emerged as significant predictors of intentions. The findings could support the design of more effective safety campaigns and interventions to reduce pedestrians' distracted crossing behaviors.

More screen operation than calling: The results of observing cyclists' behaviour while using mobile phones

Operating a mobile telephone while riding a bicycle is fairly common practice in the Netherlands, yet it is unknown if this use is stable or increasing. As such, whether the prevalence of mobile phone use while cycling has changed over the past five years was studied via on-road observation. In addition the impact of mobile phone use on lateral position, i.e. distance from the front wheel to the curb, was also examined to see if it compared to the results seen in previous experimental studies.Bicyclists were observed at six different locations and their behaviour was scored. It was found that compared to five years ago the use of mobile phones while cycling has changed, not in frequency, but in how cyclists were operating their phones. As found in 2008, three percent of the bicyclists were observed to be operating a phone, but a shift from calling (0.7% of cyclists observed) to operating (typing, texting, 2.3% of cyclists) was found. In 2008 nearly the complete opposite usage was observed: 2.2% of the cyclists were calling and 0.6% was texting. Another finding was that effects on lateral position were similar to those seen in experimental studies in that cyclists using a phone maintained a cycling position which was further away from the curb. It was also found that when at an intersection, cyclist's operating their phone made less head movements to the right than cyclists who were just cycling. This shift from calling to screen operation, when combined with the finding related to reduced head movements at intersections, is worrying and potentially dangerous.
