The University of Idaho hosts this outstanding collection of educational materials and laboratories related to transportation engineering. The topics introduced on the site are intended to supplement a junior-level course on the subject and are commonly viewed as “”the most important ones that civil engineering graduates need to understand.”” Each chapter of the lab manual contains detailed theory and example problems. The lab exercises, however, will probably only serve to emphasize the most important concepts for students whose teachers are not directly incorporating them into the curricula.
