Scope and Objectives

The project proposes a city-scale mobile crowd-sensing framework using portable sensing devices and mobile phone sensors to achieve the following objectives: (a) to measure and analyze (air, sound) pollution levels and to determine road conditions (potholes, bumps) in real-time, (b) to study the inherent causalities between poor road conditions and pollution levels in cities, (c) to present insights derived to city agencies on a dashboard, and as personalized mobile alerts to commuters, (d) to employ opportunistic and participatory sensing models, (e) to explore incentive mechanisms and reputation models to scale participatory crowd-sensing.

Deliverables

1 Prototype design of a low cost, GPS enabled, 3G enabled, battery operated, portable AQM devices for sensing PM 2.5, SOx, NOx, CO, temperature and humidity which may be placed statically in outdoors or be mounted on vehicles. 2 System to detect report road conditions, pollution levels, and field deployment a mobile phone app + server application to collect and display reported data separate apps for detecting road conditions, air sound pollution. 3 Web dashboard for real time visualization real time of road conditions, pollution levels in Mumbai Durgapur Chandigarh spatio-temporal variations. Also use suitable inference models for providing estimates of air quality and noise level index in city locations where real-time sampled data is not available. 4 Route recommender for commuters, based on pollution road time we will integrate an early-warning system for drivers of vehicles, based on conditions on current road. Commuters can also be provided with route recommendations based on the profiles of pollution levels across the city. 5 Incentive mechanism, data veracity framework for participatory sensing: to scale to a city-wide user base, we will develop incentive mechanisms that ensure user engagement as a continual process. We will incorporate a data veracity model which validates the usefulness of reported data in both automated and participatory sensing scenarios.

Scientific Output

Our SafeStreet system for crowd-sourced road anomaly detection has been field tested on about 2000 cabs in Bangalore and Mumbai. We have done extensive ground-truth validation using the data collected and have fine tuned our algorithms to improve detection accuracy. CityMap, a system to generate annotated city transit map has been developed. ComfRide, a comfortable route recommendation system has been developed. We have created a aata repository of various pollutants obtained from different types of sensors.

Results and outcome till date

Our SafeStreet system for crowd-sourced road anomaly detection has been field tested on about 2000 cabs in Bangalore and Mumbai. The CityMap and ConfRide systems has been deployed and tested over various routes of Kolkata, Durgapur and Bhubaneswar Deployed more sensors that are capable of sensing PM2.5, PM10 and CO at multiple locations (including indoor and outdoor locations) in the city of Chandigarh. Data is collected on daily basis and is compared with existing sensors in order to calibrate the fixed sensors. Sensors capable of sensing PM2.5, PM10, CO, temperature and humidity have been deployed at 7 distinct locations in the city of Chandigarh in order to understand the spatio-temporal nature of pollutants. Data is collected through internet (SIM cards installed in sensors) in JSON format on the servers of PEC. Data is collected from October 2017 and currently we have repository of almost 10 months. Dashboard is being developed at PEC Chandigarh to visualize and analyze the air pollution data received from these sensors. Various metrics like MAX, MIN, Average for each pollutant are displayed in the tabular form. Graphical representations can also be visualized on the dashboard.
