Metro effect: Pollution levels dip slightly after inauguration of new line

Submitted by Editor on Mon, 2016-07-11 12:09 Bengaluru: The inauguration of 18.1 km stretch of Metro from Byappanahalli to Nayandahalli seems to have reined in pollution levels on roads falling between these areas to an extent.A study conducted by the Karnataka State Pollution Control Board (KSPCB) after the Metro began functioning found a dip in Respirable Suspended Particulate Matter (RSPM). “Ambient Air Quality Monitoring Equipment placed at Victoria Road and Majestic premises have shown the reduction in RSPM level. The particulate matter has decreased by 6 percent on Victoria Road and by 46 percent at Majestic,” said B Nagappa, Scientific Officer, KSPCB.According to Metro officials, residents who commute to the city’s central parts from Nayandahalli and surroundings are now parking their vehicles at Nayandahalli, Mysore Road, Magadi Road metro stations. “According to our estimates, about 3,500 vehicles are off the roads. The commuters take Metro and park their vehicles near Metro station,” said UA Vasanth Rao, Chief Public Relation Officer, Bengaluru Metro Rail Corporation Limited.He said BMRCL would make arrangements for parking at various stations especially at Central Business District areas. “In next three months, work on parking facilities will be completed. As a result, another 4,000 vehicles could be parked at these lots,” he added.But Nagappa said residents commuting from Nayandahalli to Satellite Bus Terminus on Mysore Road were still relying on autos, which was a matter of concern. “The RSPM level shoots up in this 2km stretch due to the movement of autos,” said Nagappa, adding that a method named laser rope technique could measure the frequency of vehicles.“But it costs Rs3 lakhs. Now the traffic department records the movement through video cameras,” he said.     Traffic Department officials are also relieved at the reduction in vehicle numbers.“The five traffic police stations in West Division were always stressed out due to the slow moving traffic in Vijaynagar, Byatarayanpura, Upparpet, Chickpet and Magadi Road,” said GA Jagadish, Assistant Commissioner of Police, Upparpet Sub-division.“Now with Metro covering these stretches, about 3,000 motorists, who work in central part of city, park their vehicles at Metro stations,” he said.Air quality level before and after the launch of metro            City Railway Station        Victoria Road                      Before            After           Before       AfterRSPM:    123.5           66.5             128       120.0
