The fly overs are helpful for bringing down the pollution levels at the busy junctions. They are used not only for avoiding the traffic congestion but now-a-days they are helpful for bringing down the pollution levels. The RSPM (Respirable Suspended Particulate Matter(RSPM) is above normal levels and while noise levels are just above the average value.
Every day air quality data summary report will be collected at different places including the environmentally sensitive areas like Zoo park and KBR park by AP Pollution Control Board(APPCB). During this study, the RSPM and TSPM , the levels of sulphur dioxide, oxides of nitrogen and carbon monoxide in the air are being noted.
These flyovers are reducing noise and pollution for very less levels. Even the traffic congestion is not reduced because of the fly overs.
According to the analysis of APPCB, RSPM levels are decreasing at a lower quantities on a monthly basis. They are decreased from 114 mg/m3 in April to 105mg/m3 in May. The same decrement is observed in 329 mg/m3 in March to 312 mg/m3 in May.
The noise levels are also not minimized much using the Fly overs. The noise levels are more than standard levels i.e. 65 DB and are 72 DB in the day time. During the night time the level is around 90 db which is very high.
Even at the environmental sensitive places like Zoo park and KBR park noise levels are high due to heavy vehicular movement at night time when compared to day time.
According to the analysis the highly polluted areas are the Kukatpally and Langar Houz. The Kukatpally RSPM and TSPM levels are 114 and 356 mg/m3. The Langarhouz RSPM and TSPM readings are 113mg/m3 and 324 mg/m3 respectively. All these readings are of the month May 2010. These rise is due to the construction activity, heavy vehicular movement and traffic congestion.
