Time series analysis of seven years of data from the Fatal Accidenet Reporting System (FARS) shows some interesting seasonal and long term trends. The number of bicyclist accidents is essentially a seasonal phenomenon with little long-term change. Motorists and pedestrian accidents are also largely seasonal, but have increased in number overall for the seven years available for study. Bicycle accidnets can be modeled as a function of motorist and pedestrian accidents.
