Assessing the impact of road traffic on cycling for leisure and cycling to work
BACKGROUND To explore the relationship between leisure and commuter cycling with objectively measured levels of road traffic and whether any relationship was affected by traffic levels directly outside of home or in local neighbourhood. FINDINGS We conducted a secondary analysis of data from the UK European Prospective Investigation of Cancer (EPIC) Norfolk cohort in 2009. We used a geographi...
متن کاملSuspension settings for optimal ride comfort of off-road vehicles travelling on roads with different roughness and speeds
This paper reports on an investigation to determine the spring and damper settings that will ensure optimal ride comfort of an off-road vehicle, on different road profiles and at different speeds. These settings are required for the design of a four stage semi-active hydro-pneumatic spring damper suspension system (4S4). Spring and damper settings in the 4S4 can be set either to the ride mode o...
متن کاملApplications of Mathematical Models of Road Cycling
This contribution discusses several use cases of mathematical models for road cycling. A mechanical model for the pedaling forces is the basis for an accurate indoor ergometer simulation of road cycling on real-world tracks. Together with a simple physiological model for the exertion of the athlete as a function of his/her accumulated power output, an optimal riding strategy for time trials on ...
متن کاملDeveloping Non-skid Road Surfaces
In the second direction, accompanying this outdoor ex posure, will be the standard laboratory tests on these same materials after they have been subjected to freezing and thaw ing, wetting and drying. Such laboratory work will, when compared to the outdoor experiment, tell us whether or not it is necessary to go through the actual construction of a test road in order to find out what may othe...
متن کاملDIFFUSE REFLECTANCE MEASUREMENTS FROM DIFFERENT SURFACES
Relative diffuse reflection measurements from the original and ground surfaces using a He-Ne laser are reported. The intensity measurements for the metallic, transparent dielectric, matte plastic surfaces and colored papers are presented. Our results indicate that among metallic surfaces tested, aluminum has the highest diffuse reflectance; while the original stainless steel surface shows the l...
