This paper examines differences in accident characteristics and causation at different blood alcohol levels among 372 accident involved motorcycle riders who were tested shortly after they crashed. The subjects were part of a large, prospective, in-depth study of 1082 accident-involved motorcyclists in Thailand in which investigators went to the scene immediately after a crash to collect and an...

The most common form of motorcycle collision in the UK occurs when another road user fails to give way and pulls out from a side road in front of an oncoming motorcyclist. While research has considered these collisions from the car driver's perspective, no research to date has addressed how motorcyclists approach these potential hazards. This study conducted a detailed analysis of motorcyclist ...

The aim of this study was to analyse the effect of forces applied to pedals and cranks on the strain imposed to an instrumented bicycle motocross (BMX) frame. Using results from a finite element analysis to determine the localisation of highest stress, eight strain gauges were located on the down tube, the seat tube and the right chain stay. Before the pedaling tests, static loads were applied ...

To optimize the performance of off-road bicycle suspension systems, a dynamic model of the bicycle/rider system would be useful. This paper takes a major step toward this goal by developing a dynamic system model of the cyclist. To develop the cyclist model, a series of four vibrational tests utilizing random inputs was conducted on seven experienced off-road cyclists. This allowed the transfer...

The recent boom in the demand for off-highway vehicle (OHV) recreation has created an important policy issue for public land managers who are concerned with the impacts of OHV use on environmental quality. Within the past few years, the U.S. Forest Service has recognized the need for greater authority in managing these recreation areas and has proposed to amend OHV regulations. However, not muc...

We investigate policy reform in a model in which there are both rent seeking and lobbying activities. These two activities involve similar skills, so a reform which reduces rents will cause a shift into lobbying. Also, lobbying is subject to a free-rider problem, so the marginal return to the industry from lobbying may greatly exceed an individual firm’s return to lobbying. Thus, the shift into...

Recent advancements in mobile technology allow global positioning system (GPS)-enabled cell phones to provide a variety of real-time location-based services. This study reports on the design, implementation and testing of such a service, the travel assistance device (TAD), that aids transit riders with special needs in using public transportation. TAD is a program that provides the rider with c...
