IGI Metro line to have GIS security

The showcase Airport Express Line touted as Delhi Metro Rail Corporation’s jewel in the crown has added another feather to its cap. The line, which will run between Connaught Place and Indira Gandhi International (IGI) Airport in 18 minutes, will be mapped on Geographic Information System (GIS) to enhance safety, maintenance and traffic regulation, a first of its kind exercise in India.

Mapping the 22.7-km Metro corridor expected to become operational by September 2010 on GIS will help in mobilizing emergency services in case of an accident.

Delhi Airport Metro Express Private Limited, a Special Purpose Vehicle (SPV) created to build the line, will map all the emergency services, including fire stations, police stations and hospitals along the alignment, said a senior spokesperson of the consortium. The spokesperson said that the company has already made some maps for the Delhi alignment. Once the construction of the corridor is complete, locations of the piers, viaduct and stations will be imported to GIS. ‘‘GIS technology will enable efficient maintenance of the Metro line and it will have layers ranging from technical details of pillars, piers and transformers,’’ the spokesperson added.

The layers correspond to the Metro corridor, utilities, and land base including roads, landmarks, buildings, rivers and railway crossings. It also maintains information on the equipment like underground cables, transformers, piers, viaduct, stations and tracks.

‘‘With the help of GIS maps the exact location of the fault along the network can be determined and maintenance team can be dispatched immediately. This will ensure speedy maintenance and a better and reliable service,’’ the spokesperson said.
