OBJECTIVES This study examined the variation in the U.S. road fatality rate per distance driven across the months of the year. METHOD The monthly fatality rates were analyzed for a 13-year period from 1994 through 2006. RESULTS The results indicate a systematic seasonal variation in the road fatality rate, with the highest rate in October and the lowest rate in March. CONCLUSION The obtai...

A spatial preference query ranks objects based on the qualities of features in their spatial neighborhood. For example, consider a road network database with available paths for two points. A customer may want to rank the paths with respect to their distance defined after aggregating the qualities of other features (road condition, travelling time, traffic monitoring and road length) within a d...

The objective of an accident-mapping algorithm is to snap traffic accidents onto the correct road segments. Assigning accidents onto the correct segments facilitate to robustly carry out some key analyses in accident research including the identification of accident hot-spots, network-level risk mapping and segment-level accident risk modelling. Existing risk mapping algorithms have some severe...

BACKGROUND Rheumatoid arthritis (RA) is a chronic systemic inflammatory disease that affects approximately 1% of the adult population, and to date, genetic factors explain < 50% of the risk. Particulate air pollution, especially of traffic origin, has been linked to systemic inflammation in many studies. OBJECTIVES We examined the association of distance to road, a marker of traffic pollution...

Anti-lock braking system (ABS) is the most common safety system in the vehicles, which works to increase the generated braking force between the tire and the road surface for enhancing passenger safety specifically related to accident avoidance. However, designing an ABS is a challenging task considering the fact that it is highly nonlinear and a time varying system. The interaction between the...

Parametric cubic spline curves are commonly used to model the geometry of road surfaces in real-time driving simulators. Roads are represented by space curves that define a curvilinear frame of reference in which three-dimensional points are expressed in coordinates of distance along the curve, offset from the central axis, and loft from the road surface. Simulators must map from global Cartesi...

[Purpose] The purpose of this study was to determine the effects of chewing gum on driving performance in a driving simulator. [Subjects] In total, 26 young licensed drivers participated. [Methods] The driving scenario was typical of an urban environment: a single-carriageway, two-way road consisting of a mix of curved and straight sections, with considerable levels of traffic, pedestrians, and...

The paths of 2425 individual motorcycle trips made in London were analyzed in order to uncover the route choice decisions made by drivers. The paths were derived from global positioning system (GPS) data collected by a courier company for each of their drivers, using algorithms developed for the purpose of this paper. Motorcycle couriers were chosen due to the fact that they both know streets v...
