Advance Warning of Stopped Traffic on Freeways

Pages : 148
Book Description
A major safety concern on freeways is traffic flowing at normal speed encountering unexpected slow or stopped traffic. Traffic can be queued due to recurrent congestion, work zones, or collisions and/or other incidents. Drivers encountering queues are often faced with rapidly changing conditions in terms of queue length, sight distance to the end-of-queue, terrain, and available warning devices for traffic control. The rear-end collision is the most common type of multi-vehicle freeway collision, often due to slow/stopped traffic on the main lanes. This report summarizes the first year of this effort, which was to conduct the literature review, to determine current practices for advance warning for stopped traffic, to observe field locations with traffic stopped due to various congestion conditions, and to determine advance warning techniques applicable to Texas.

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.
