Book Description
The report reviews an experiment undertaken to examine the effectiveness of five sign treatments for controlling driver speeds in the vicinity of hazardous horizontal curves on rural two-lane highways. Signs examined ranged from the standard curve warning arrow to a regulatory speed zone sign in conjunction with a curve warning sign. Data collected during the experiment included both the following electronic and manual data: speeds of motorists as they approached and negotiated two horizontal curves, vehicle classification and registration information, and whether vehicles crossed over center and edge line markings.

Book Description
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
