If Point Name During Edits is set to Named on the Options > Geometry menu; alignment key Highway engineering is an engineering discipline branching from civil engineering that involves the planning, design, construction, operation, and maintenance of roads, bridges, and tunnels to ensure safe and effective transportation of people and goods. Highway engineering became prominent towards the latter half of the 20th century after World War II Geometric Design Geometric design for transportation facilities includes the design of geometric cross sections, horizontal alignment, vertical alignment, intersections, and various design details. These basic elements are common to all linear facilities, such as roadways, railways, and airport runways and taxiways Importance of geometric design • The geometric design of a highway deals with the dimensions and layout of visible features of the highway such as alignment, sight distance and intersection. • The main objective of highway design is to provide optimum efficiency in traffic operation with maximum safety at reasonable cost Highway Plan Reading Manual February, 2014 4 This manual has been prepared to introduce the general aspects of highway plan preparation techniques and to assist in the interpretation of both construction and right of way plans. Since different standards have been applicable throughout the years, no two highway plans may look identical

Highways serve as the lifeline of a developing nation. Even in the developed nations, highways play an important role in connecting cities and establishing an industrial link between two or more places. Highway construction and engineering is comprised of planning, designing, and executing. Construction of highway does not mean construction of roads only, but it includes various aspects like.

The design hourly volume (DHV) is usually the 30th highest hourly volume for the design year, commonly 20 years from the time of construction completion. For situations involving high seasonal fluctuations in ADT, some adjustment of DHV may be appropriate. For two-lane rural highways, the DHV is the total traffic in both directions of travel Compaction Control Moisture - Density - Strength Relationship Proof Rolling Embankment Failure Winter Earthwork Reference is made throughout the guide to the Standard Specifications, Standard Sheets, plans, proposals and various procedure manuals. It is intended that the guide will stimulate the reader to study these sources Where highway design or reduced visibility conditions make it desirable to provide control or to guide vehicles through an intersection or interchange, such as at offset, skewed, complex, or multi-legged intersections, on curved roadways, where multiple turn lanes are used, or where offset left turn lanes might cause driver confusion, dotted. Road Intersection is where two or more roads meet and or are the points of potential vehicle conflict. They are critical element of a road section. They are normally a major bottleneck to smooth flow of traffic and a major accident spot. The general principles of design in both rural and urban areas are the same
