MUST | MOBILE URBAN SENSING TECHNOLOGIES
We have developed Mobile Urban Sensing Technologies (MUST) to collect high spatio-temporal resolution urban environmental data. Urban data are generally collected through fixed urban stations, which typically offer a low spatial resolution coverage. Recent literature has widely demonstrated the strong environmental gradients present in cities; however, outside research realms, these spatial environmental gradients are generally unknown and rarely discussed, and thus cities fail to implement effective urban policies to resolve the often-drastic urban environmental gradients and concomitant environmental inequality. This project proposes to use mobile sensing as a methodology to acquire data at higher spatial resolutions. We have developed various sensing kits that can be coupled to different mobile platforms, from wearables, to bikes, to private vehicles or public transportation networks.
MUST SENSING KITS COUPLED TO VEHICLES
The novelty of the proposed sensing methodology resides in its flexibility to mount the kit on any type of mobile vehicle such as private cars or public transportation networks. Readily available and low-cost sensors are used to enable the scalability of the project. The sensing kits are also equipped with a GPS shield that enables the kits to be geo-localized in real time. Furthermore, the kit also comprises a cellular antenna that enables the acquired data to be transmitted in near real time to an online database
must sensing kits coupled to drones
A low payload MUST sensing kit was developed and coupled to UAV technologies to capture 3-dimensional environmental data of an urban area. A customized lightweight 3D printed container was designed to enable the require minimum air flow for the correct functionality of the sensors, while shielding them from the direct exposure to rain and radiation. An adjustable connector hook was designed to attach the sensing kit to the drone base aiming to minimize the transfer of vibrations to the sensor case.
MUST SENSING KITS As wearables
A compact MUST sensing kit was designed to perform pedestrian level urban environmental mapping. A laser cut case was manufactured to provide sufficient resilience for an intensive crowd sourced pedestrian level urban environmental mapping campaign. The sensing kit was tested in the Tongji University Shanghai campus in Summer of 2018.
REAL TIME DATA VISUALIZATION
We are currently developing a field experimental campaign within Princeton University campus with a new MUST sensing kit version mounted on private vehicles and on Princeton University public transportation network.
We have developed mobile and web apps to make the collected data available in real time.
