Observed Risk and User Perception of Road Infrastructure Safety Assessment for Cycling Mobility

The opportunities for data collection in smart cities and communities provide new approaches assessing risk of roadway components. This paper presents compares two different methodological cycling safety assessment objective perceived risk. Objective was derived from speed direction profiles collected with Global Navigation Satellite System (GNSS) camera installed on an instrumented bicycle. Safety critical events between cyclists other road users were identified linked to five A panel experts asked score the severity using a Delphi process reach consensus. To estimate risk, web-based survey provided city bicyclist community asking them same components 4-point Likert scale. comparison classification showed good agreement when only higher conflicts considered. research findings support notion that it is possible collect information bicycle probe match user perceptions thus, utilizing take advantage such advancing goals communities.
