Book excerpt: The fifth volume of the Wiley Series in Environmentally Conscious Engineering, Environmentally Conscious Transportation provides a foundation for understanding and implementing methods for reducing the environmental impact of a wide range of transportation modes, from private automobiles (with a separate chapter on biofuels) to heavy trucks and buses to rail and public transportation systems to aircraft. Each chapter has been written by one or more experts who, based on their hands-on field experience, present relevant practical and analytic techniques for enhancing the integrity and reliability of transportation vehicles and infrastructure, as well as for measuring and limiting the pollution caused by transportation activities. Moreover, the book explains how to satisfy key business objectives, such as maximizing profits, while meeting environmental objectives.
