Estimating Bicycling Demand

Simple and reliable tools for estimating and predicting the amount of bicycling in an area would be useful for a variety of investment and policy decisions. Previous efforts to develop such tools have typically tried to develop demand estimates from basic descriptors of the population, land use, and bicycling facilities of an area. This paper takes an alternative approach using the idea of deri...

Sidewalk Bicycling Safety Issues

Bicycle route and safety datasets for 2963 commuter cyclists in Ottawa and Toronto, Canada containing cyclist characteristics, collision and fall history, and regular commute route, are used for this analysis. Previous analyses found sidewalk collisions, fall and injury rates significantly higher on sidewalks versus roads or paths. Of the 52 events reported on sidewalks none were reported to po...

Valuing Public Investments to Support Bicycling

ing from leisure trips that serve no purpose of transportation, getting from A to B conveys disutility to people in the form of money, time, effort, fear of accidents and other costs, the sum of which are usually referred to as generalized costs. In the context of bicycling, the generalized costs are almost exclusively nonmonetary and thus internal to cyclists. The existence of internal costs f...

A pedal dynamometer for off-road bicycling.

This paper describes the design and accuracy evaluation of a dynamometric pedal, which measures the two pedal force components in the plane of the bicycle. To realize a design that could be used during actual off-road cycling, a popular clipless pedal available commercially was modified so that both the form and the function of the original design were maintained. To measure the load components...
