A Study and Design of Two Lane with Paved Shoulder in Green Filed Corridor, By Using Civil 3D

Abstract

Geometric design is important component, which have a majority of effect while designing a new alignment of the road as per present trends, which is skeleton of any alignment of road. It is combination of cross-sectional elements, horizontal alignments, sight distance considerations and vertical alignment details, attributes of intersection. It also considers other macro factors like design speed, terrain or topography, traffic plying and expected, design hourly volume and estimated capacity, along with environmental factors. While aligning a new road, it should be short, easy, safe and economic and it is expected to be comfort and safe for the movement. Rural road is a road network with a low volume traffic and low design speed which provides market access to farms, employment and connects different communities. Rural roads are classified into Another District Road (ODR) and Village Road (VR). These roads are able to reach the group of villages in rural area of the country and to provide connectivity. It is owned by local authorities. AutoCAD Civil 3D is a software application used by civil engineers and professionals to plan and design the projects for building constructions, road engineering projects, water include construction of dams, ports, canals, embankments etc. AutoCAD civil 3D associate design and production drafting, greatly reducing the time it takes to implement design changes and evaluate multiple situations. A change made in one place immediately updates an entire project, helping your complete projects faster, smarter and more accurately. Civil 3D provides to create 3D models of the project and helps to adopt for both small- and large-scale projects. It helps to imagine the things in 3D visualization, reduces the time and budget. It also inherits many benefits of using civil 3D. Total station is a combination of Electronic Distance Measurement (EDM), an electronic digital theodolite, and a computer in one unit used to measure horizontal angles, vertical angles and sloping distances of the objects. It takes a part by providing all the three co-ordinates of the observed points that is northing, easting, and elevation. These points are further transferred into AutoCAD civil 3D. The term is used in Carriageway, Shoulder, Earthen Shoulder, Typical Cross Section, Utility Corridor, Horizontal and Vertical Alignment, Sight Distance, Design Speed, Topography, Intersection, Traffic Survey etc. The object of the project was to demonstrate how roadway geometric design can be Design in Green Filed Corridor a very short time with much ease and precision. Also, to understand the Green Field Design and its aspects. the road design procedure using AutoCAD Civil 3D has been presented. Manual geometric design of the same road was also performed, the results of which was compared favourably with that of AutoCAD Civil 3D. Also, In this study is to examine in detail the availability of road/highways transport infrastructure and working of the roads/highways at national level. To identify and analyze the problems associated with the roads/highways in India with respect to design per say.
