A team from the Indian Institute of Technology (IIT) will be analysing the impact of the odd-even scheme, which will be rolled out from November 4 in Delhi, using real-time pollution monitoring devices invented by students.

The monitoring will be done from October 15 to November 15 to study the effectiveness of the car-rationing scheme in improving air quality.

The six-member team has invented sensor-based pollution monitoring devices called "Eziomotiv" which has been patented and has received ICAD certification too.

"The devices will be placed atop around 250 buses running in the national capital to gauge air quality. The devices will help calculate Particulate Matter (PM), heat, temperature and humidity across different terrains, traffic movement, weather and times of the day. We have tied up with the Delhi Integrated Multi-Modal Transit System (DIMTS) for the purpose," Pooja Singh from IIT Delhi's incubation unit told PTI.

"Each bus makes 16 trips daily, covering different routes with each of them being around 30 to 40 kms long. The devices have camera and are GPS enabled so we can also track the vehicle's movements," she added.

The study will be conducted in two phases--pre odd-even and odd-even."To analyse whether the scheme was impactful or not we also need data of  preceding days to compare with. Hence, it will be done in two phases and we will analyse whether the quality improved or not during odd-even and if yes by how much percentage," she added.

The devices that will be used have been invented at IIT through the incubated start up 'Aerogram'. The IIT's Centre of Excellence for Research on Clean Air, had provided the initial funding for the project. Other members of the team include--Manoj Sahukar, Faheem Ashraf, Sahil Siwach, Bhaskar Dutt and Surbhi Kumari.
