Intersections are an important part of a highway facility because the efficiency, safety, speed, cost of operation, and capacity of the facility depend on the intersection design to a great extent. Each intersection involves through- or cross-traffic movements on one or more of the highways and may involve turning movements between these highways. Such movements may be facilitated by various geometric designs and traffic controls, depending on the type of intersection. Designers need current information regarding intersection design in an easily accessible and user-friendly format in order to design intersections that are both functional and effective. The prime objective of TxDOT Project 0-4365 is to produce a reference document, the Intersection Design Guide, which will provide TxDOT and other interested parties with useful and practical information on operations and design for intersections. |
