The introduction to this report includes a description of bicycle use patterns and the effects of development patterns on bicycle transportation. Useful references on this include:
Forester, John: Bicycle Transportation. 1994, MIT Press, Cambridge Massachusetts. See especially the section on "Parameters of practical bicycling" beginning on page 22. While most advocates of bicycling argue against sprawl development on environmentalist grounds, Forester makes an unconventional but compelling point, that sprawl development may actually encourage bicycling for the same reason as it encourages motoring -- basic services are not within walking distance.
The Demographics of Commuting in Greater Boston. 1989, Central Transportation Planning Staff, Boston. This study points especially to the imbalance between housing and employment in the Route 128 corridor -- including the Metrowest area -- and how this increases travel distances. Though the study does not specifically deal with bicycling, its conclusions are essential to an understanding of travel patterns in general.
References on bicycle routes in the Boston area include:
French, Keith: Boston Area Bicycle Guide. 1970's, out of print. A collection of 25 loop tours, this described many of the best through routes in the western suburbs and provides a "baseline" comparison with current conditions.
Massachusetts Bicycle Map. 1987, Boston, Department of Public Works. Out of Print. Revised edition published by Rubel Bikemaps
Stone, Howard: Short Bike Rides in Greater Boston and Central Massachusetts. 1982, Second edtiion 1997, Globe Pequot Press, Chester, CT 06412
In addition, the author was able to consult the map archive of the Charles River Wheelmen.
Studies which provide basic data on types and frequency of bicycle accidents include:
Bicycle-Motor Vehicle Accidents in the Boston Metropolitan Region. 1984, Boston, Metropolitan Area Planning Council.
Kaplan, Jerrold: Characteristics of the Regular Adult Bicycle User. 1975, Federal Highway Administartion, Washington, D.C.
Also note that Forester's book, cited above, gives a detailed breakdown of accident types and frequency.
