“…As for non-respondent explanatory variables in Table 3, PET is the only significant predictor of all four severity outcomes, consistent with conflict research and supporting its use in defining interactions (7,54). Higher PET is associated with higher comfort and lower risk, as expected.…”

Assessments of interactions between road users are crucial to understanding comfort and safety. However, observers may vary in their perceptions and ratings of road user interactions. The objective of this paper is to examine how perceptions of yielding, comfort, and safety for pedestrian interactions vary among observers, ranging from members of the public to road safety experts. Video clips of pedestrian interactions with motor vehicles and bicycles were collected from 11 crosswalks and shown to three groups of participants (traffic safety experts, an engaged citizen advisory group, and members of the general public) along with questions about yielding, comfort, and risk of injury. Experts had similar views of yielding and comfort to the other two groups, but a consistently lower assessment of injury risk for pedestrians in the study. Respondent socio-demographics did not relate to perceptions of yielding, comfort, or risk, but self-reported travel habits did. Respondents who reported walking more frequently rated pedestrian comfort as lower, and respondents who reported cycling more frequently rated risk as lower for pedestrian interactions with both motor vehicles and bicycles. Findings suggest small groups of engaged citizens can provide useful information about public perspectives on safety that likely diverge from expert assessments of risk, and that sample representation should be assessed in relation to travel habits rather than socio-demographics.

Bicycle-Vehicle Conflict Risk Based on Cyclist Perceptions: Misestimations of Various Risk Factors

Cycling is a sustainable but vulnerable mode of transportation. Intersections’ bicycle-vehicle crashes are particularly dangerous. This paper explores the discordance between empirical evidence and cyclists’ perceptions of the various risk factors of cycling. Ridge regression was adopted to identify risk factors from bicycle-vehicle conflict data. A questionnaire was distributed to assess cyclists’ perceptions of safety and danger over the same candidate risk factors. There was indeed discordance between the data and the questionnaire results. Cyclists appear to misestimate risk in certain factors such as bus stops and subway stations. Understanding these misestimations can provide a foundation for safety improvements and for promoting cycling as a sustainable mode of transportation.

“…Roads, streets, street crossings and other elements are shaped around motorised vehicles (Hamilton-Baillie, 2008, Guo and Ferreira, 2008, Freund and Martin, 1997. Even the introduction of a shared space concept is delivering little, if not counterproductive, benefits for pedestrians, especially to those who do not 'fit' the norm (Imrie, 2012, Karndacharuk et al, 2013, Kaparias et al, 2013, Beitel et al, 2018, Essa et al, 2018. Poor design and inadequate provisions create pedestrian-vehicle conflict (Kaparias et al, 2013, Vedagiri andKadali, 2016) with more severe implications for disabled pedestrians (Imrie, 2012, Eskyte, 2015.…”

Established on a well-consolidated global network of scholars and professionals, The Journal of Public Space is committed to expand current scholarship by offering a global perspective and providing the opportunity for unheard countries to speak up and to discuss neglected as well as emerging topics that are usually sidelined in mainstream knowledge. The Journal of Public Space is addressing social sciences and humanities as a major field, and is interested also in attracting scholars from several disciplines. It will perform as a scholarly journal but also as an interdisciplinary platform of discussion and exchange by scholars, professionals, organizations, artists, activists and citizens, whose activities are related to public space.
