“…Despite challenges with enforcing close passing laws, Schramm et al (2016) found an increase in driver awareness of bicyclists following implementation of a minimum passing law in Queensland, Australia. A video study from Ottawa found that over 90% of vehicles passed with over 1 m of lateral separation, as Ontario provincial law dictates, and that traffic density as well as passing distance affected bicyclist comfort (Apasnore et al, 2017). Mid-block crashes such as a bicycle being overtaken by a vehicle have been less studied than those in intersections yet tend to be more severe due to increased motor vehicle velocities (Pai, 2011).…”

Safety concerns are a barrier to increasing bicycling. BikeMaps.org, a tool for crowdsourcing bicycling collisions, near misses, and falls, offers rich data on local bicycling safety concerns. Our goal is to characterize dominant bicycling safety issues reported in nine Canadian cities. We analyzed 2,513 BikeMaps.org reports (522 collisions, 151 falls, 1840 near misses), and summarized the types of incidents reported, ratios of near misses to collisions by incident type and by city, and injuries resulting from various types of crashes. Incidents categorized as a 'dangerous pass, overtake at midblock', were most commonly reported and had the highest ratio of near misses to collision reports (9:1). Cities with a high commute mode share for bicycling had lower near miss to collision reporting ratios. Overall, 40.3% of reported collisions or falls required medical treatment. Incident types with the most severe outcomes were 'left cross at an intersection' (58.4% reported needing medical treatment); 'vehicles failing to stop at intersection or yield to bike' (54.0%); and 'multi-use paths, vehicle conflicts at intersection' (48.5%). Mitigating conditions leading to real or perceived concerns over dangerous passes by vehicles should improve bicycling comfort. Bicycling injuries will be reduced by safety improvements at intersections including those with multi-use paths.

“…For example, on arterial roads, black spots were situated where there are overtaking-prohibited lanes (with marked lines). The results indicate that 72% of the conflicts at these locations were inappropriate lateral collisions, while few were frontal and rear collisions, emphasising the importance of maintaining adequate lateral clearance between bicycles and motorised vehicles (see References [98,124,125]). Physical lane boundaries or divisional facilities (e.g., channelization) may prevent vehicles from lane changes, effectively reducing BMV crash risks on arterial roads (Wang et al, 2019) [20].…”

“…The dimension of road engineering facilities [98,123] may also have a significant effect on the risk of BMV crashes. The risk may be attributed to the increased size of arterial road junctions.…”

Integrating Spatial and Temporal Approaches for Explaining Bicycle Crashes in High-Risk Areas in Antwerp (Belgium)

The majority of bicycle crash studies aim at determining risk factors and estimating crash risks by employing statistics. Accordingly, the goal of this paper is to evaluate bicycle–motor vehicle crashes by using spatial and temporal approaches to statistical data. The spatial approach (a weighted kernel density estimation approach) preliminarily estimates crash risks at the macro level, thereby avoiding the expensive work of collecting traffic counts; meanwhile, the temporal approach (negative binomial regression approach) focuses on crash data that occurred on urban arterials and includes traffic exposure at the micro level. The crash risk and risk factors of arterial roads associated with bicycle facilities and road environments were assessed using a database built from field surveys and five government agencies. This study analysed 4120 geocoded bicycle crashes in the city of Antwerp (CA, Belgium). The data sets covered five years (2014 to 2018), including all bicycle–motorized vehicle (BMV) crashes from police reports. Urban arterials were highlighted as high-risk areas through the spatial approach. This was as expected given that, due to heavy traffic and limited road space, bicycle facilities on arterial roads face many design problems. Through spatial and temporal approaches, the environmental characteristics of bicycle crashes on arterial roads were analysed at the micro level. Finally, this paper provides an insight that can be used by both the geography and transport fields to improve cycling safety on urban arterial roads.

“…The first direction of study analysed in a vast array of publications refers to cyclists' interactions with other road users in the context of different infrastructural solutions, most often in relation to potential conflict situations (Silvano et al 2016;Stipancic et al 2016;Apasnore et al 2017;Pokorny et al 2018) and those resulting in accidents (Pokorny et al 2017;Lopez et al 2017). Research also covers the relationship between factors contributing to cyclists' collisions with vehicles and the severity of their injuries (Kim et al 2007).…”

Environmental pollution in cities is an increasingly popular issue tackled in research. One of the elements with a significant impact on the state of urban ecosystems is transport with its pressure on individual components of the environment. Sustainable urban transport is gaining prominence as a postulate expressed in cities’ strategic documents, constituting an element alleviating the negative effects of anthropopressure. In the light of the need to introduce innovative solutions for clean forms of transport, numerous papers indicate the bicycle as an answer to some of those problems. The article presents a review of literature referring to the socio-economic aspects of using the bicycle in cities as a means of transport for daily commuting. The analysis is based on publications on cyclist safety in road traffic, the perception of the bicycle as a means of transport in cities, and the introduction of innovative solutions, such as bicycle-sharing systems.
