Safety Problems in Urban Cycling Mobility: A Quantitative Risk Analysis at Urban Intersections

摘要: The attention to the most vulnerable road users has grown rapidly in recent decades. experience gained reveals an important number of cyclist fatalities due crashes; which occur at intersections. In this study, dispersion trajectories urban intersections been considered identify whole conflict area and largest areas between cars bicycles, speeds have used calculate exposure time cyclists reaction available drivers avoid collision. These data allow summary approach problem, while a risk probability model developed adopt elementary analysis. A quantitative damage proposed classify each point, probabilistic defined consider traffic volume unit exposure. combination probability, permitted assess crash, examined intersection. Three types four-arm intersection, with without bike paths, were considered. For scheme, authors assessed collision vehicle. obtained results allowed identification hazardous maneuvers highlighted that geometry kinematics movements cannot be overlooked, when designing strategy by could significant impact on management hazard estimation methodology design safer
