Outline
To guide healthy travel for cyclists in hot weather，a cycling measurement platform using micro-sensors was developed to collect high-resolution data on cyclists' heart rates，as well as atmospheric particulate matter (i.e.，PM2.5，PM10，and BC(Black Carbon) on the non-motorized lanes of the Western Third-Ring Expressway in Fuzhou. Statistical analyses were conducted to characterize and interpret variations in cyclists' heart rates. Results indicate that cyclists' average heart rates near residential zones are higher than that of riverside segments，showing strong and sustained associations with all measured particulates. The number of diesel vehicles，ambient temperature，and atmospheric pressure are found to significantly influence the heart rate changes across sections of the entire route，riverside，and residential sections，respectively. Cyclists' heart rates also fluctuate due to varying environmental and topographical conditions along the route. Immediate effects of PM2.5 and BC on heart rate are observed，while PM10 effects are delayed. Therefore，implementing road-segment-specific control measures for motor vehicles，particularly strict regulation of those emitting pollutants with immediate effects on cyclists，and guiding the selection of routes with better roadside ventilation and higher greenery coverage，can effectively enhance the travel quality for cyclists.
