INFORMATION FOR CONTRIBUTORS.

The article presents information for authors who want their research work to be published in the journal "Transportation Science." The submission of a manuscript is taken to be the author's representation that the manuscript has not been published or accepted for publication in books or recognized journals and is not currently under consideration by another journal. Manuscripts for publication and Letters to the Editor should be submitted to the Editor either directly or to one of the Associate Editors. Tables may be typed on sheets separated from the text. Manuscripts must be double-spaced throughout with the original in typewritten or equally legible form. Figures are required in a form suitable for photographic reproduction. Any one of a number of forms will be acceptable, e.g., original black ink drawings, or high-quality glossy prints. In mathematical expressions, authors are requested in general to minimize unusual or expensive typographical requirements. Authors should strive for conciseness and clarity. References to related previous work should be reasonably complete, consecutively numbered, and grouped at the end of the paper.
