Delhi-Ghaziabad-Meerut RRTS Corridor Length: 82.15 km Not merely connecting two cities but serving Underground Elevated 82 km of urban strip 1.City-center to city-center , high-speed dedicated rail connectivity 2. Train every 5-10 minutes , serving traffic nodes every 5-10 kms – 24 stations 3. Seamless multimodal connectivity with other modes of transport 4. Will serve 800,000 passenger trips per day 5. Modal shift from private to public transport – 37% to 63% – 100,000 vehicles off the road
What is RRTS & What will it offer to its users? RRTS – Rail based high speed, high capacity, comfortable and safe commuter service connecting regional nodes. It will help in reducing Road Congestion, Energy Consumption and Pollution Design speed of 180 kmph Train every ~5-10 min. & serving Universal Access + Safety – Interoperable Corridors & (Delhi to Meerut in 60-65 min) traffic nodes every 5-10 kms Platform Screen Doors Multimodal Integration High capacity, comfortable Reduced Land use for high Commuter friendly Weather proof – rains, fog journey, airline seating throughput information system RRTS trains will travel at 3 times the average speed of Metro
Ascertaining the Alignment Best Route vs Availability of ROW
Alignment Consideration ROW availability is most essential Multiple corridors are chosen, approx. cost is worked out and traffic survey is carried out for each corridor Best route is selected based on the parameters of above study Various possible alignments are marked Cost, time required for construction, requirement of land acquisition, ratio of Elevated/ Underground are important criteria in working out most suitable option Even during construction phase minor alignment adjustments become very important because of site constraints or change in planning of other stake holders

About Survey Techniques & Outcomes Knowing the real objective of the survey is the key
Topographical Survey for Alignment ➢ Preliminary Alignment of RRTS corridor fixed on Google earth map keeping in view proposed station locations, land availability, obligatory points, construction technology, multimodal integration etc. ➢ Before commencement of construction, Topographical survey required to prepare base map for: ▪ Fine tuning/ geometric design of alignment as per design speed etc for marking same on ground ▪ Determining quantities for earthwork in embankment, cutting etc for cost estimation etc ▪ Exact location of obligatory points such as existing tunnels, bridges, rivers, flyovers, buildings etc for final alignment design ▪ Determining locations of various utilities such as electric lines, sewer lines, water lines etc to plan their shifting etc ▪ Working out exact quantities of land requirement ➢ Accuracy level of Toposurvey depends on type of construction. For railway lines, high grade accuracy level required ( 1 in 50,000 )
Topographical Survey using Total Station • Establishment of Primary Control Points (at about 50 km interval) using DGPS adopting basic principle of surveying from “whole to part” • Establishment of Secondary Control points (at about 25 km interval) and Tertiary Control Points (at about 5 km interval ) PCPs • Transfer of level from known Benchmark in the vicinity of the area to be surveyed to Control Points in the survey area by closed traverse as per required accuracy level ( 6√K mm ) • Fixing of coordinates of intermediate points at about 100-150m by Traversing by Total Station from one control point to another control point as per required accuracy level ( 1 in 50,000 ) • Capturing coordinates of all visible natural and manmade features such as road, railway line, bridge, culvert, buildings, trees, sewer lines, drains, river etc., in the survey area with the Total station • Transfer of data from Total station to computer • Plotting of data in AutoCAD to create Topographical map
Topographical Survey by Aerial Photogrammetry using Drones in Manesar area (1/3) • Establishment of Ground Control Points by DGPS Survey in the survey area • Selection of appropriate Drone with high resolution camera (4K) and Flight Planning according to area required to covered • Aerial Photos taken with pre decided overlap ( minimum 75% end overlap and minimum 60 % side overlap (side)
Topographical Survey by Aerial Photogrammetry using Drones in Manesar area (2/3) • Obtaining permissions for flying in the intended area from local Authorities/DGCA • Taking Aerial Photographs by flying drone over the intended area • Transfer of Data (Vertical Aerial Photographs) from Camera/Drone to Computer
Topographical Survey by Aerial Photogrammetry using Drones in Manesar area (2/3) • Aerial photographs Georeferenced with coordinates of Ground Control Points by using appropriate photogrammetry software such as Pix4D , Autodesk ReCap etc. to create orthophoto map, DTM, DSM, Point Cloud, Contour Maps etc. • Orthophoto map exported in CAD supported format (ecw etc.) and Topographical Survey sheets prepared by tracing the ground features in the CAD software. • Accuracy of Toposheets depend upon Ground Sampling Distance (GSD) (distance measured on the ground between successive pixel centers in an image). Accuracy of about 5-10 cm achieved Orthophoto (from software) Toposheet prepared by tracing
