“…In this respect, "dwell-time fixation" is defined by a minimum fixation duration of 100 ms and a maximum visual angle variation of one degree. Consistent with protocol from similar studies [36,[42][43][44], if the visual angle varies up to one degree, it means that the gaze is fixed; the end of a fixation is defined when the eye deviates from the fixation start position by more than one degree. The list of variables measured in this study are presented in Table 1 with their description; Table 2 presents how the analysis is segmented by type of intersection and experience level.…”

“…Our investigation uses a variety of eye gaze measures to capture the behavior of cyclists around signalized intersections. Specifically, eye gaze measures can be approached as proxy for the visual workload of the cyclist [36] and the amount of cortisol activity; we aim to understand differences by cyclists' experience level and type of intersection. Furthermore, we quantify characteristics of eye gaze to inform aspects of street design.…”

The manner in which cyclists visually perceive elements of the urban environment plays an important role in bicycle crashes, which have been increasing in recent years. Yet, how visual information is processed by the user while riding a bike is still poorly analyzed by researchers. This study investigates cyclists’ eye gaze behavior at signalized intersections taking into account a set of gaze characteristics. Recording cyclist’s visual fixations by mobile-eye glasses in a real outdoor environment, a total of 13 field tests have been analyzed along a three-kilometer route in the urban center of Bologna, Italy. Findings reveal key differences in gaze behavior by experience level of the cyclist and type of intersection.

Cycling as a Smart and Green Mode of Transport in Small Touristic Cities

Abstract:Cycling as a mode of transport is a low-cost, health-improving way to travel and offers environmental benefits for the cities that promote it. It is only recently, though, with concerns over climate change, pollution, congestion, and obesity among others, that have cities throughout the world have begun to implement policies to promote cycling. In Greece, however, the use of the bicycle is limited. In Preveza, a small touristic city in Northwestern Greece where the use of the bicycle is prominent when compared to other Greek cities, there are efforts to promote cycling. Through the aid of a structured questionnaire, the residents evaluated the suitability of the city for cycling, the existing infrastructure, appropriate education, and behavior of cyclists and drivers. More than half of the residents use bicycles as their transportation and stated that bicycles are an inexpensive way of transport in the city and had the opinion that the state should encourage bicycle use by supporting subvention in bicycle acquisition. Two-thirds of the residents evaluated the cycling facilities of their city as adequate, but unsafe for young cyclists who do not follow the rules of transport. Adult cyclists, in contrast, were more loyal to the code, but stated that drivers did not respect their presence on the roads. This research provides important information on the perceived shortcomings of cycling as a transport mode in Preveza that may be of interest to towns/cities with similar characteristics.

“…Therefore, researchers are now executing a growing number of experiments in real-world environments. Multiple eye tracking experiments exist that analyze pedestrians' [Brügger et al 2018;Davoudian and Raynham 2012;Fotios et al 2015a,b;Kiefer et al 2014Kiefer et al , 2012Wenczel et al 2017] or cyclists' behavior [Mantuano et al 2016;Schmidt and von Stülp-nagel 2018;Vansteenkiste et al 2014]. In contrast to existing works, we are presenting a visual analytics-based approach to explore patterns, extract common eye movement strategies, and enable a combined analysis of the multi-modal data.…”

“…Whereas researchers have analyzed the visual perception of car drivers in many eye tracking experiments [Kapitaniak et al 2015], there are only few experiments performed with pedestrians and cyclists. In recent years, researchers have published a growing number of eye tracking experiments analyzing pedestrians and cyclists (e. g., [Davoudian and Raynham 2012;Kiefer et al 2012;Mantuano et al 2016;Vansteenkiste et al 2014;Wenczel et al 2017]). In this paper, we apply a visual analyticsbased method to analyze gaze behavior of pedestrians and cyclists in a real-world eye tracking experiment.…”
