Abstract It is well known that bicycling in urban areas has beneficial effects on people's health and well-being. On the other hand, urban cycling, especially during the morning and evening commute, may be associated with health and safety risks due to potentially high levels of exposure to air pollution, road noise, and high traffic density. Few studies have, however, measured cyclists' exposure to noise and air pollution simultaneously. The objective of this research is to evaluate cyclists' exposure to air pollution and noise in central city neighbourhoods of Montreal and to identify the impact on exposure of associated local factors such as weather conditions, the day and time, the type of road, bicycle path or lane used and the characteristics of the immediate environment around the cyclist's route. A total of 85 bicycle trips were analyzed, representing 422km of travel and nearly 25h of data collection. The mean exposure levels were 70.5dB(A) for noise and 76μg/m3 for nitrogen dioxide (NO2). A very weak negative correlation was found between the two measures of exposure (R2 =−0.07, p =0.005). The results of the spatial regression models show that the morning commute and trips on collector roads and on-street bike lanes and shared bike lanes have significant and positive impacts on exposure to air pollution and noise. On the other hand, some factors are only significant for one or the other of the two types of exposure.

    Highlights A weak correlation was found between exposure to noise and air pollution. On-street bike lanes and shared bike lanes are associated with higher levels of exposure to the two nuisances. Off-street bicycle paths are associated with lower levels of air pollution but have no significant impact on noise. The proximity of the off-street bicycle path to the closest road increases the level of exposure to noise.
