Street typology and bicyclist safety : a systems approach
Cycling is an attractive transportation mode but has not attained a large mode share in the United States, in part because it is correctly perceived as dangerous. Much literature on cyclist safety and the built environment has focused on bicycle facilities such as bike lanes, while fewer studies …

Towards Safety-Assured Environments of Autonomous Robots via Intent Expressive Autonomy
… and autonomous-vehicle-to-bicyclist feedback displays. We studied several possible options for an external vehicle display for effective nonverbal communication between an autonomous vehicle and vulnerable road users to identify a feedback module, which increases most …

Characterizing Bicyclists Behavior in Overtaking Scenarios Over Different Road Infrastructures
… The purpose of this study was to characterize bicyclist behavior to enhance the crash avoidance potential of advanced driver assistance systems and improve safety for cyclists. An analysis on fatal crashes involving bicyclists was conducted to determine scenarios for testing bicyclist-vehicle …

Predictive models for accidents on urban links - A focus on vulnerable road users
… in the models for motor vehicle accidents. For bicyclist accidents the correct exponent for bicyclist flows is likely to be somewhat lower than 0.5, close to 0.35. The study also recommended practical uses for the models, listed the lessons learned from the modelling as well as proposed a number …

Measuring low stress bike access to MARTA
… based on amount of traffic stress perceived by a bicyclist. The concept builds on research indicating that bicyclists can be grouped based on their comfort level. Riders identifying as strong and fearless as well as enthused and confident bicyclists represent most of the current users of the …

Exploring image recognition: applying convoluted neural networks and learning to recognize safe cyclists
… the mix. With statistics showing an increase in bicyclist related crashes over the last decade and an increase in bicycle-borne road users, there is a necessity for cities and autonomous vehicles to build bicycle safety into their adaptation to the ""driverless future"". This paper is an …

Effectiveness of Automatic Emergency Braking for Protection of Pedestrians and Bicyclists in the U.S.
… in 2018, of which 20% were pedestrians, bicyclists, and other vulnerable road users (VRUs) [1]. Vulnerable road users are non-vehicle occupants who, because they are not enclosed in a vehicle, are at higher risk of injury in traffic crashes. While overall traffic fatalities in the US have …

Exploring Personality Traits and Susceptibility to Social Influence in Student Change-Agents: Implications for Participation in a Campus-Wide Safety Initiative
… The intervention involved approaching bicyclists on campus, discussing the importance of helmet use, and rewarding them with a coupon for a discounted helmet if they signed a promise to wear one. Change-agent volunteers (n = 82) were trained in one of three commitment conditions to …

Applying Log-linear Models And GIS To Study The Safety Of Pedestrians And Bicyclists : A Case Study Of Orange County School Children
… on school zone safety related to pedestrian/bicyclist crashes. Most of the studies pertained to crashes with all age groups. There have been few studies with emphasis only on school aged children. In this study we focus on pedestrian age group (4 to 18 years), the time of the day when the …

Towards a Comprehensive Bicycle Motion Behavior Model and Naturalistic Cycling Dataset
… to characterizing the longitudinal motion of bicyclists based on the assumption that there is no significant differences between the dynamics of a single-file bicycle traffic and the longitudinal motion behavior of cars. This research reparametrizes an existing car-following model to describe …

Analysis Of Type And Severity Of Traffic Crashes At Signalized Intersections Using Tree-based Regression And Ordered Probit Models
… model showed that crashes involving a pedestrian/bicyclist have the highest probability of a severe injury. For motor vehicle crashes, left turn, angle, head-on and rear-end crashes cause higher injury severity levels. Division (a median) on the minor road, as well as a higher speed limit on the …
