Environmentally friendly, but behaviorally complex? A systematic review of e-scooter riders' psychosocial risk features

Sensation seeking and crashes among young cyclists

While young cyclists remain overrepresented in cycling crash figures, effective actions to mitigate their risks remain understudied and underapplied, especially in regions with low cycling tradition and weak or fragmented governance, as is the case in most Hispanic countries. One key emerging issue is the potential influence of personality traits such as sensation seeking (SS) on young cyclists' behavior and safety outcomes. This study aimed to assess the relationships among SS, cycling behavior, and safety-related outcomes among a sample of young cyclists. Data were collected from 945 cyclists aged 18-25 from five Hispanic countries, who responded to an electronic survey on personality traits and cycling-related topics. Significant associations were found between sensation seeking and risk-related cycling behaviors, as well as gender differences in SS, risky cycling behavior, and self-reported cycling crash rates, with males exhibiting higher values in all categories. Path analyses suggest that SS predicts self-reported crashes through the full mediation of both deliberate (traffic violations) and unintentional (errors) risky road behaviors, with the former having a greater explanatory effect on young cyclists' self-reported crash figures. The findings of this study highlight the need to address under-researched issues such as sensation seeking (SS) and risk-taking behavior through evidence-based interventions aimed at improving the safety of young cyclists. This is particularly relevant in countries with similar demographic characteristics and further nascent cycling cultures.

An analysis of e-scooter-related trauma in Ireland: an update

AIMS

Electronic (E)-scooters have become increasingly common in Ireland. Our group was the first to publish an analysis of injuries related to these devices in Ireland in 2021. Since then, the use of e-scooters has increased significantly. The primary aim of this study was to re-analyse the trend in scooter-related trauma 4 years later.

METHODS

We conducted a retrospective analysis over the same time period as our previous study (13 months). Seventy-six patients with e-scooter-related trauma in our emergency department (ED) were identified between June 2023 and July 2024. Medical records and patient imaging were reviewed. Injury severity score (ISS) was calculated, and results were compared to our previous study.

RESULTS

There was an increase from 22 to 76 patients presenting to our ED with an e-scooter-related injury over a 13-month period. The number of patients presenting with fractures has risen from 15 to 34 (45%). Twenty-four per cent of ED attendees required hospital admission, and 13 patients underwent surgical intervention. The average ISS was 4.3, and helmet use has decreased significantly from 40% to 8%.

CONCLUSIONS

E-scooters remain to be a key contributor to emergency department presentations and complex orthopaedic injuries. The majority of patients require radiological investigation and specialist follow-up, with many needing surgical fixation. The effects of such injuries can have severe long-term consequences for patients and place financial constraints on our health system. With the rollout of e-scooter rental schemes and infrequent helmet use, one can expect the resulting trauma will continue to rise.

Does Academic Burnout Alleviate or Exacerbate Internet Dependence in University Students with Depression and Anxiety?

Purpose

This study aims to investigate whether academic burnout alleviates or exacerbates internet dependence among college students with depression and anxiety. Moreover, it intends to construct a moderated mediation model to examine how academic burnout moderates the relationship between depressive and anxious emotions and internet addiction and how social support mediates this relationship to determine the psychological motivations underlying addiction.

Methods

A questionnaire survey was conducted using the simple random sampling method, which yielded 757 valid responses (response rate: a 93.11% response rate). The sample included 274 males and 466 females, with an average age of 20.90 years (±1.48). Hierarchical regression analysis was employed for data analysis.

Results

Anxiety and depressive symptoms directly affect the internet dependence of university students and indirectly affect it through the mediating role of social support. Academic burnout moderates the relationship between negative emotions and internet addiction, with high levels of academic burnout potentially decreasing the internet dependence of students experiencing negative emotions. We proposed a psychological self-regulation mechanism theory, which posits that learned helplessness may intensify the emotional symptoms of anxiety and depression, which is reflected in reduced internet use behavior.

Conclusion

High levels of academic burnout can exacerbate symptoms of depression and anxiety, significantly reducing students' interest in activities. For these students, a decrease in internet addiction may not be a positive sign; instead, it could indicate worsened depression and anxiety. This finding underscores the need for close monitoring of and intervention implementation for college students experiencing high levels of burnout and symptoms of depression or anxiety.

Enhancing mutual understanding of e-scooter user's perspective in overtaking maneuver through replaying own driving trajectory

The global adoption of e-scooters as a convenient mode of micro-mobility transportation is on the rise, offering a flexible solution for covering first- and last-mile journeys. However, this surge in usage brings challenges, particularly concerning road safety, as e-scooter riders often share road space with other vehicles, heightening the risk of serious accidents. While numerous studies have explored safe overtaking behaviors and safety perceptions from drivers' viewpoints, limited attention has been given to understanding the varying safety perceptions of both drivers and e-scooter riders, particularly after riding an e-scooter and being overtaken by their own vehicles. This research aims to bridge this gap by examining variations in safety perceptions and assessing behavioral changes before and after experiencing overtaking scenarios. Specifically, the study focuses on scenarios where an e-scooter rider experiences being overtaken by a vehicle they had previously driven. A Unity-based sequential simulation process is employed to replay scenarios obtained from a vehicle simulator during an e-scooter experiment involving the same participant without their awareness. This innovative approach allows e-scooter rider participants to relive their own prior vehicle overtaking maneuvers while riding an e-scooter. The findings reveal that most participants (64%) felt less safe as e-scooter riders, influenced by factors like relative speed and acceleration of overtaking vehicles. After experiencing being overtaken by their own pre-driven vehicles, a noteworthy positive correlation emerged between safety perception and lateral distance, indicating that greater distance is derived from a better understanding of e-scooter safety. The study demonstrates the effectiveness of the sequential simulation strategy in fostering safe driving behavior and raising road safety awareness. Experiencing overtaking behaviors firsthand as an e-scooter rider, previously behind the wheel of the overtaking vehicle, encourages a heightened awareness of road safety. These findings have significant implications for road safety authorities, suggesting the potential application of this approach in driver education programs. By incorporating such interventions tailored to improve the safety of vulnerable road users, authorities can take proactive steps towards mitigating risks associated with micro-mobility transportation.

'I mean, I wouldn't say I was sober': Exploring the psychosocial impact of e-scooter injuries and aligning a collaborative public health response

ISSUE ADDRESSED

E-scooters are sought after for their cost-effectiveness, sustainability, and efficiency in urban transportation. However, this popularity has been accompanied by a surge in injuries, prompting a deeper investigation into the factors influencing risk perceptions among e-scooter users.

METHODS

Using a qualitative approach, we conducted 19 interviews with those who attended an emergency department as a result of e-scooter injury. We aimed to understand the psychosocial effects of these incidents and employed thematic analysis to discern recurrent patterns in participants' experiences, focusing on alterations in daily life, community response, perception shifts, and avenues to enhance safety awareness.

RESULTS

The findings underscored significant disruptions to daily life due to injuries, demonstrating enduring impacts on lifestyle and wellbeing. Participants exhibited a perceptual shift, transitioning from perceiving e-scooters as enjoyable to viewing them as dangerous. Recommendations for enhancing safety awareness included accessible and clear safety education, pre-ride briefings, real-time safety guidance, temporal rental restrictions, and mandatory breathalysers before e-scooter use.

CONCLUSIONS

The study underscores the importance of considering not only the individual experiences and perceptions of e-scooter injuries but also the broader social context, including the night-time economy. Leveraging peer narratives and community engagement is vital to reshape risk perceptions and promote harm reduction messages. SO WHAT?: A comprehensive approach through proactive interventions and robust educational strategies is essential to foster responsible e-scooter usage and prioritise public safety.

Different but also alike? Ingroup-outgroup phenomena among cyclists and e-scooter riders

PROBLEM

In many countries, a new road user group, e-scooter riders, share the existing cycling infrastructure. The study aimed to investigate if an individual's status as a cyclist or e-scooter rider affects their social identity and whether it results in ingroup favoritism or outgroup discrimination.

METHOD

An online experiment involving 179 cyclists and 64 e-scooter riders was conducted, where they rated the behavior of ingroup or outgroup members in six traffic scenarios.

RESULTS

Participants rated dispositional attributions as more causally relevant than situational ones across all traffic scenarios. Cyclists and e-scooter riders were inclined to judge ingroup members' rule violations more harshly than those of outgroup members in terms of dispositional attribution ratings and punishment severity. For situational attributions, few indications of ingroup favoritism were observed for the e-scooter rider group.

SUMMARY

Findings suggest initial indications of considerate coexistence, from the perspective of social identity theory, between the two modes of transport, supporting current regulations on the use of cycling infrastructure by e-scooter riders. Indications of ingroup discrimination, however, suggest that safety campaigning may target to promote courtesy within the cyclist and e-scooter rider groups.

Understanding nonuse of mandatory e-scooter helmets

OBJECTIVES

Head injuries resulting from e-scooter use have led to calls for helmet use to be promoted or mandatory. Helmet use is mandatory for e-scooters in Australia but observational studies have reported significant levels of nonuse, particularly by riders of shared e-scooters. The aim of this study is to understand whether nonuse in the mandatory context is a consistent behavior for an individual or is situationally-influenced, and what are the factors associated with nonuse.

METHODS

An online survey was completed between 2022 and 2023 by 360 adult e-scooter riders in Canberra, Australia. Riders were asked whether they had worn a helmet on their last ride and how often they had not worn a helmet when riding in the last 30 days. The survey also asked about rider characteristics (demographics, frequency of e-scooter and bicycle use, perceived risk of e-scooter use, e-scooter ownership, and risky behaviors while riding), trip duration and perceptions of the helmet requirement (knowledge of and support for the law).

RESULTS

Respondents were mostly male, young, highly educated, and full-time workers. Of the 29.1% of riders who reported riding without a helmet in the last 30 days, 24.4% had worn a helmet at least once during that period and 4.8% had consistently not worn a helmet. Younger age, shared e-scooter use and more frequent riding frequency (shared e-scooters only) were associated with helmet nonuse in the bivariate analyses but not in the logistic regression. Logistic regression showed that the independent predictors of helmet nonuse were the number of risky riding behaviors, lack of knowledge, and lack of support for the law.

CONCLUSIONS

Most nonuse of helmets in a mandatory context seems to be situational, rather than consistent. Many of the factors associated with nonuse of helmets for e-scooters are similar to those reported for bicycles. Nonuse of helmets appears to be one of a number of risky behaviors performed by riders, rather than being primarily an outcome that is specific to factors associated with helmets (e.g., concerns about hygiene, discomfort or availability).

Riding practices of e-bike riders after the implementation of electric bike management regulations: An observational study in Hangzhou, China

Objective

This study aimed to understand the riding behaviors of electric bike (e-bike) users in Hangzhou after the "Regulations of Zhejiang Province on the Administration of Electric Bicycles".

Methods

The study consisted of two parts, including a questionnaire survey of local e-bike users in Shangcheng District and Jiande County in Hangzhou City, and a cross-sectional observational study of 16 intersections.

Results

A total of 789 e-bike riders participated in the questionnaire survey, and the riding behavior of 99,407 e-bike users was observed. The main purpose of using e-bike was work and daily life, 46.0% of them used e-bikes more than 5 days a week, and 58.5% used e-bikes for less than 30 min each time. A vast majority (81.7%) of e-bike riders believe that the implementation of Zhejiang Regulations has significantly improved the safety level of e-bike riding in the region. The field survey found that the correct rates of helmet wearing by e-bike riders and passengers were 78.83% and 42.27%. The main violations were invalid/non-helmet wearing (21.17%), followed by carrying passengers and running red lights (7.94% and 4.26%). The rates of invalid/non-helmet wearing and running red lights were significantly higher during non-morning rush hour, weekends, and roads without separate non-motorized vehicle lanes than in other conditions (all P < 0.05). Additionally, sunny days and crossroads were risk factors for passenger-carrying and invalid/non-helmet wearing compared to rainy/cloudy days and T-intersections.

Conclusions

The phenomenon that e-bike users' correct practice lags far behind the awareness of various violations has shown some improvement. To further enhance safety measures for e-bike riders, it is necessary to promote education, improve infrastructure, and strengthen law enforcement, in support of the "Zhejiang Regulations" and behavioral interventions.

E-scooters: Still the new kid on the transport block. Assessing e-scooter legislation knowledge and illegal riding behaviour

The use of e-scooters is rapidly increasing in cities, leading to their integration into the transportation system. However, numerous collisions involving e-scooters, including some resulting in fatalities, have been reported since their introduction. These incidents indicate that the potential dangers posed by e-scooters may be underestimated. Research suggests that a significant factor contributing to these collisions is the prevalence of illegal riding behaviour exhibited by many riders. This paper presents three studies that aimed to assess the understanding of e-scooter riders and non-riders of the current legislation across various riding scenarios and link it to their profile, riding habits, and their proneness to engage in illegal riding behaviours. Study 1 utilised questionnaires to survey participants and gather information about their profiles and self-reported illegal riding behaviour. Study 2 focused on assessing participants' knowledge of the current e-scooter legislation through different everyday riding scenarios. Study 3 featured short video clips from the rider's perspective to determine the proneness of participants to engage in illegal riding behaviour and explore the potential relationship between these behaviours and their understanding of e-scooter rules. The findings revealed that e-scooter riders were generally younger and exhibited a higher propensity for engaging in illegal riding behaviour than non-users. Both groups demonstrated limited knowledge regarding various aspects of the current e-scooter legislation, particularly related to parking, speeding, and designated infrastructure. While e-scooter riders demonstrated relatively greater knowledge of the e-scooter rules, this was not consistently observed across all areas, particularly in relation to riding on pavements (pedestrian footpaths). Furthermore, Study 3 revealed that participants with better knowledge of the current legislation were less likely to engage in illegal riding behaviour. These findings suggest a need for targeted interventions and educational campaigns to improve riders' understanding of regulations and promote safer riding practices. Implementing training programs for e-scooter safety could significantly enhance riders' awareness of the associated dangers, fostering responsible e-scooter use.

The Impact of the City of Miami's Decision to Revoke Electric Scooter Company Permits on Orthopedic Trauma at a Level I Trauma Center

BACKGROUND

Since the introduction of electric-scooter (e-scooter) mobile applications, there has been a marked increase in e-scooter-related injury. On January 19, 2022, the City of Miami revoked permits to five major mobile applications for violation of safety protocols.

OBJECTIVES

The purpose of our study was to assess the effects of this notice on the orthopedic patients seen at our corresponding Level I trauma center.

METHODS

Institutional Review Board approval was obtained for this study. A retrospective chart review was performed including all patients with orthopedic injuries at our Level I trauma center between July 19, 2021 and July 19, 2022. These dates include 6 months prior to and after the major e-scooter operators ceased use in Miami. SPSS statistical software version 28.0.0 (SPSS, IBM, Armonk, NY) was utilized for all statistical analysis.

RESULTS

There were 2558 patients in the prenotice cohort, and 2492 patients in the postnotice cohort. After the notice, there was a significant decrease in the number of patients that presented to our institution due to injuries caused by e-scooters (2.8% vs. 1.8% patients; p = 0.021). Patients with injuries caused by e-scooters had a significantly lower age (38 vs. 42, respectively; p = 0.034) and were more likely to be male (79.3% vs. 67.4% male, respectively; p = 0.007) than patients with other orthopedic injuries.

CONCLUSION

This study demonstrates that the 2022 notice revoking the major mobile application operators from the City of Miami resulted in a significant decrease in the number of orthopedic cases due to e-scooter-related injury at the corresponding Level I trauma center.

E-scooter attitudes and risk-taking behaviours: an international systematic literature review and survey responses in the West Midlands, United Kingdom

Introduction

Micromobility initiatives, including electric scooters (e-scooters), are part of the United Kingdom government's sustainability drive. Since summer 2020, multiple trials have been conducted across the United Kingdom. Safety concerns have been raised around e-scooters joining other vehicles on United Kingdom roads, alongside the numerous private e-scooters illegally ridden on public land. Although literature has been published abroad on perceptions, risk-taking behaviours and attitudes surrounding e-scooters, independent United Kingdom research has concentrated on analysing trauma. Our aim was to identify common themes and recommendations to form conclusions on factors affecting e-scooter trauma hospital admissions.

Methods

A systematic literature search in June 2023 extracted studies focused on the primary outcomes of risk factors, perceptions, and attitudes surrounding e-scooters globally from the EMBASE, PubMed, and Web of Sciences databases. Two independent reviewers conducted a critical appraisal to extract potential biases and study characteristics. A critical appraisal skills programme (CASP) analysis was also completed. Two online surveys distributed in Birmingham and Wolverhampton focused on: public perception towards e-scooters, and road user attitudes around e-scooters. The target population was residents of the West Midlands who were both riders and non-riders of e-scooters. The surveys were opened in late-March 2023 and closed in late-July 2023.

Results

443 studies were retrieved with 13 studies being eligible according to our inclusion and exclusion criteria. CASP assessment concluded that the studies were of good quality, however heterogeneity meant sample sizes could not be meaningfully aggregated. Many studies focused on safety concerns whilst others observed risk-taking behaviour, non-rider perceptions, and infrastructure. Our surveys received 299 responses and respondents reported risk-taking behaviours such as pavement riding, alcohol consumption, and minimal helmet use. However, positive opinions were expressed on e-scooter convenience but concerns were raised regarding rider and non-rider safety.

Discussion

Whilst global literature had investigated e-scooter attitudes, risk-taking behaviours and perceptions, there was no comparable independent United Kingdom literature. Our literature review and analysis of survey responses concluded that e-scooters were perceived as a sustainable form of transport; however, safety concerns were raised. Our study points to risk-taking behaviours by riders being associated with admissions into hospital emergency departments. We conclude that well maintained infrastructure could improve the safety of both e-scooter riders and vulnerable pedestrians, whilst education and enforcement of clear rules may reduce risk-taking behaviour. The recommendations found in the PACTS reports, and documents from the RNIB confirm our findings. We recommend that hospital data and future studies should differentiate between private and rental e-scooters for robust conclusions to be made.

Investigation on changes in the usage patterns of Seoul Bike usage patterns owing to COVID-19 according to pass type

Human mobility has been significantly impacted by varying degrees of social distancing and stay-at-home directives that have been implemented in many countries to prevent the spread of COVID-19; this effect was observed regardless of the mode of transportation. Several studies have indicated that bike-sharing is a relatively safe option in terms of COVID-19 infection, and more resilient than public transportation. However, previous studies on the effects of COVID-19 on bike-sharing, rarely considered the type of pass in their investigation of the pandemic-induced changes in usage patterns of shared bikes. To overcome this limitation, this study used trip records obtained from Seoul Bike to investigate the changes in usage patterns of shared bikes during the COVID-19 pandemic. The spatiotemporal usage patterns were characterized in this study based on the type of pass. Additionally, using t-tests and k-means clustering, we discovered significant factors that influenced changes in one-day pass usage rates and temporal usage patterns at the station level. Finally, we constructed spatial regression models to estimate changes in bike rentals caused by COVID-19 based on pass type. The findings provided a comprehensive understanding of how bike-sharing usage varies depending on pass type, which is closely related to shared bikes trip purposes.

E-scooter riders and pedestrians: Attitudes and interactions in five countries

Electric scooters (e-scooters) have become a popular phenomenon internationally; however, their use has raised concerns about pedestrian safety. This study describes the possible effects of the emergence of e-scooters on pedestrians. We focus on the interaction, conflicts, crashes, and attitudes between pedestrians and e-scooter riders and pedestrians' perceived safety in the presence of e-scooters. Data were collected from e-scooter riders and non-riders (n = 3385) through an online survey in Australia, Belgium, the Czech Republic, Norway, and Sweden. Around 20-30% of e-scooter riders rode on sidewalks, whether it is allowed or not. Non-riders of e-scooters tended to report that riding an e-scooter is rather dangerous. Pedestrians, except Australian ones, perceived e-scooter riders (and e-scooter operation) as annoying. Half of the e-scooter riders had experienced a near miss at some point in the past and more than 50% of these near misses included another road user. Up to 10% of the e-scooter riders from all five countries reported having experienced a crash. On the basis of these findings, we believe that the most relevant suggestions for the implications in sustainable (urban) mobility involve separating e-scooter riders and pedestrians.

Differences in perception of safety in driving environment according to shared PMD user experience through multi-criteria analysis

A shared personal mobility device (PMD) is a transportation model that rents personal transportation devices, such as bicycles and kickboards, through a sharing platform. The use of shared PMD has increased, but related complaints and traffic accidents are doubling with it every year. This study applied an analytic network process (ANP) methodology for the multi-criteria analysis. A survey including normal citizens was conducted to evaluate the importance of safety regarding shared PMD experience. The evaluation factors differ according to the experience of using the shared PMD device, although 'driving continuity' and 'separation of sidewalks and roadways' were the most important. PMD users gave greater priority to 'removal of the road gap', 'traffic safety signs', 'dedicated parking area' and 'management of obstacles' compared to non-users. On the other hand, for non-PMD users, 'bicycle lane width', 'strengthening enforcement', and 'user safety education' were more important. The results showed that importance differed depending on the participant's experience of using a shared PMD or the lack of it. In the case of users, factors that have a direct effect on driving were prioritised, and in the case of non-users, auxiliary operations and management, such as crackdowns and education, were prioritised.

A quantitative traffic performance comparison study of bicycles and E-bikes at the non-signalized intersections: Evidence from survey data

As common transportation modes at non-signalized intersections, bicycles and e-bikes have been involved in most traffic crashes. Although a large number of studies have been dedicated to studying the safety problems caused by bicycles and e-bikes, there is still limited attention paid to the differences between them, especially at non-signalized intersections. This paper compares the differences between bicycles and e-bikes based on a self-administered questionnaire. This questionnaire was distributed to bicycle users (N = 453) and e-bike users (N = 439). The personal characteristics, decision-making capacity, the feeling of infrastructure, perceived level of service, and perceived level of risk were adopted as the performance indicators to depict the difference in the study area. Using statistical methodologies and the Structural Equation Model (SEM), key findings indicate that perceived level of service was found to be significantly different between bicycles and e-bikes at most non-signalized intersections. 43.4 % of e-bike riders often or always choose to avoid riding under extreme weather, while 58.7 % of bicycle riders avoid riding under extreme weather. Moreover, compared with bicycles, e-bikes' decision-making capacity is affected more by infrastructure quality. The difference between bicycles and e-bikes highlights the need for differentiated development of cycling safety education and law enforcement.

A Geographical and Temporal Risk Evaluation Method for Red-Light Violations by Pedestrians at Signalized Intersections: Analysis and Results of Suzhou, China

Red-light violations of pedestrians crossing at signal intersections is one of the key factors in pedestrian traffic accidents. Even though there are various studies on pedestrian behavior and pedestrian traffic conflicts, few focus on the risk of different crosswalks for the violating pedestrian group. Due to the spatio-temporal nature of violation risk, this study proposes a geographical and temporal risk evaluation method for pedestrian red-light violations, which combines actual survey and video acquisition. First, in the geographical-based risk evaluation, the pedestrian violation rate at signal intersections is investigated by Pearson correlation analysis to extract the significant influencing factors from traffic conditions, built environment, and crosswalk facilities. Second, in the temporal-based risk evaluation, the survival analysis method is developed to quantify the risk of pedestrian violation in different scenarios as time passes by. Finally, this study selects 16 typical signalized intersections in Suzhou, China, with 881 pedestrian crosswalk violations from a total size of 4586 pedestrians as survey cases. Results indicate that crossing distance, traffic volume on the crosswalk, red-light time, and crosswalk-type variables all contribute to the effect of pedestrian violation from a geographical perspective, and the installation of waiting refuge islands has the most significant impact. From the temporal perspective, the increases in red-light time, number of lanes, and traffic volume have a mitigating effect on the violations with pedestrian waiting time increases. This study aims to provide a development-oriented path by proposing an analytical framework that reconsiders geographical and temporal risk factors of violation. The findings could help transport planners understand the effect of pedestrian violation-related traffic risk and develop operational measures and crosswalk design schemes for controlling pedestrian violations occurring in local communities.

Characteristics and Risk Factors for Electric Scooter-Related Crashes and Injury Crashes among Scooter Riders: A Two-Phase Survey Study

Electric scooters (or e-scooters) are among the most popular micromobility options that have experienced an enormous expansion in urban transportation systems across the world in recent years. Along with the increased usage of e-scooters, the increasing number of e-scooter-related injuries has also become an emerging global public health concern. However, little is known regarding the risk factors for e-scooter-related crashes and injury crashes. This study consisted of a two-phase survey questionnaire administered to a cohort of e-scooter riders (n = 210), which obtained exposure information on riders' demographics, riding behaviors (including infrastructure selection), helmet use, and other crash-related factors. The risk ratios of riders' self-reported involvement in an e-scooter-related crash (i.e., any crash versus no crash) and injury crash (i.e., injury crash versus non-injury crash) were estimated across exposure subcategories using the Negative Binomial regression approach. Males and frequent users of e-scooters were associated with an increased risk of e-scooter-related crashes of any type. For the e-scooter-related injury crashes, more frequently riding on bike lanes (i.e., greater than 25% of the time), either protected or unprotected, was identified as a protective factor. E-scooter-related injury crashes were more likely to occur among females, who reported riding on sidewalks and non-paved surfaces more frequently. The study may help inform public policy regarding e-scooter legislation and prioritize efforts to establish suitable road infrastructure for improved e-scooter riding safety.
