The effects of mobile phone use on cycling behaviour were studied. In study 1, the prevalence of mobile phone use while cycling was assessed. In Groningen 2.2% of cyclists were observed talking on their phone and 0.6% were text messaging or entering a phone number. In study 2, accident-involved cyclists responded to a questionnaire. Only 0.5% stated that they were using their phone at the time of the accident. In study 3, participants used a phone while cycling. The content of the conversation was manipulated and participants also had to enter a text message. Data were compared with just cycling and cycling while listening to music. Telephoning coincided with reduced speed, reduced peripheral vision performance and increased risk and mental effort ratings. Text messaging had the largest negative impact on cycling performance. Higher mental workload and lower speed may account for the relatively low number of people calling involved in accidents. STATEMENT OF RELEVANCE: Although perhaps mainly restricted to flat countries with a large proportion of cyclists, mobile phone use while cycling has increased and may be a threat to traffic safety, similar to phone use while driving a car. In this study, the extent of the problem was assessed by observing the proportion of cyclists using mobile phones, sending questionnaires to accident-involved cyclists and an experimental study was conducted on the effects of mobile phone use while cycling.

The Netherlands is well known for their high bicycle use. We used the Health Economic Assessment Tool and life table calculations to quantify the population-level health benefits from Dutch cycling levels. Cycling prevents about 6500 deaths each year, and Dutch people have half-a-year-longer life expectancy because of cycling. These health benefits correspond to more than 3% of the Dutch gross domestic product. Our study confirmed that investments in bicycle-promoting policies (e.g., improved bicycle infrastructure and facilities) will likely yield a high cost-benefit ratio in the long term.

Many governments attempt to improve cycling safety to reduce the number of bicycle crashes and encourage people to take up cycling. The Netherlands is a world leader in bicycle use and safety. This paper explores how the Netherlands achieved an 80% reduction in the number of cyclists killed (predominantly bicycle-motor vehicle crashes) per billion bicycle kilometres over a thirty year period. Factors found to contribute to this improvement include the establishment of a road hierarchy with large traffic-calmed areas where through traffic is kept out. A heavily used freeway network shifts motor vehicles from where cycling levels are high. This reduces exposure to high-speed motor vehicles. Separated bicycle paths and intersection treatments decrease the likelihood of bicycle-motor vehicle crashes. The high amount of bicycle use increases safety as a higher bicycle modal share corresponds with a lower share of driving and greater awareness of cyclists among drivers. Low cycling speed was also found to contribute to the high level of cycling safety in the Netherlands.

The world is currently witnessing its largest surge of urban growth in human history; a trend that draws attention to the need to understand and address health impacts of urban living. Whilst transport is instrumental in this urbanisation wave, it also has significant positive and negative impacts on population health, which are disproportionately distributed.In this paper, we bring together expertise in transport engineering, transport and urban planning, research and strategic management, epidemiology and health impact assessment in an exercise to scope and discuss the health impacts of transport in urban areas. Adopting a cross-disciplinary, coproduction approach, we explore the key driving forces behind the current state of urban mobility and outline recommendations for practices that could facilitate positioning health at the core of transport design, planning and policy.Current knowledge on the health-related impacts of urban transport shows that motor vehicle traffic is causing significant premature mortality and morbidity through motor vehicle crashes, physical inactivity and traffic-related environmental exposures including increases in air pollution, noise and temperature levels, as well as reductions in green space. Trends of rapid and car-centred urbanisation, mass motorisation and a tendency of policy to favour car mobility and undervalue health in the transport and development agenda has both led to, and exacerbated the negative health impacts of the transport systems. Simultaneously, we also argue that the benefits of new transport schemes on the economy are emphasised whilst the range and severity of identified health impacts associated with transport are often downplayed. We conclude the paper by outlining stakeholders recommendations for the adoption of a cross-disciplinary co-production approach that takes a health-aware perspective and has the potential to promote a paradigm shift in transport practices.

ObjectivesTo study cyclists’ share of transport modes (modal share) and single-bicycle crashes (SBCs) in different countries in order to investigate if the proportion of cyclist injuries resulting from SBCs is affected by variation in modal share.MethodsA literature search identified figures (largely from western countries) on SBC casualties who are fatally injured, hospitalised or treated at an emergency department. Correlation and regression analyses were used to investigate how bicycle modal share is related to SBCs.ResultsOn average, 17% of fatal injuries to cyclists are caused by SBCs. Different countries show a range of values between 5% and 30%. Between 60% and 95% of cyclists admitted to hospitals or treated at emergency departments are victims of SBCs. The proportion of all injured cyclists who are injured in SBCs is unrelated to the share of cycling in the modal split. The share of SBC casualties among the total number of road crash casualties increases proportionally less than the increase in bicycle modal share.ConclusionsWhile most fatal injuries among cyclists are due to motor vehicle–bicycle crashes, most hospital admissions and emergency department attendances result from SBCs. As found in previous studies of cyclists injured in collisions, this study found that the increase in the number of SBC casualties is proportionally less than the increase in bicycle modal share.
