“When I saw all these scooters on campus, I realized they not only carry people, but can also carry sensors that can help us collect data, which is great for all these technological advances we want to make,” Jadliwala said. “That also got me thinking that by obtaining data from them, we can study the impact of scooters on pedestrian safety.”
So, in effect, Jadliwala created a UTSA research laboratory operation called ScooterLab. Funding came from a $100,000 grant from the National Science Foundation (NSF) for a one-year pilot program to develop the concept. Other co-principal investigators include Greg Griffin, assistant professor in the UTSA Department of Urban and Regional Planning; Sushil Prasad, assistant professor in the UTSA Department of Computer Science; and Anindya Maiti, assistant professor in the University of Oklahoma Department of Computer Science.
Jadliwala and his team’s goal in this project is to turn the UTSA Main and Downtown campuses into rolling data laboratories. ScooterLab’s first two-wheeler was purchased off the shelf. But the heart of the operation is a small computer attached to the scooter. Jadliwala enlisted the help of UTSA doctoral student Raveen Wijewickrama to design and build the first data-gathering device. He used readily available parts that include a Raspberry Pi computer with several sensors attached, powered by a small battery.
“The sensors can collect GPS location, exploration and audio data that connect to our test phone through Bluetooth,” Wijewickrama said. “We can download the data from our phones for analysis. This is just a prototype. Our next version will have the capability of transmitting the data to a collection center through a 5G transmitter.”
The ScooterLab team is already working on a 2.0 version of the scooter’s computer. In addition to a 5G transmitter, improvements will include a weatherized outer case and enhanced computer design. The 5G transmitter will send data from all scooters to a centralized server located on campus.
“Our NSF funding is a small planning grant, which will enable us to think about these issues, get feedback from other researchers and develop a research community around ScooterLab,” Jadliwala explained. “Effectively, we are trying to start a small scooter company on campus, which is not a trivial task. Another consideration with micro-mobility data is you can figure out where a person lives, when he goes to work, his preferences, what he likes to eat—things like that. Collecting data in an ethical fashion and storing it securely, to ensure privacy of users, are grand challenges which we are still planning.”
This personal data is sensitive and highly sought by researchers or private companies. This is why Jadliwala feels it’s important to develop the program in house versus partnering with an established scooter business.
“Appropriating funding from government agencies or foundations gives us flexibility to do what we want to advance science without any strings attached,” Jadliwala said. “If we take funding from a private company, and they want us to do certain things, this could lead to an uncomfortable situation and create a conflict of interest with our research goals.”
If successful in securing additional funding from the NSF or another source, the first wave of ScooterLab two-wheelers will arrive on campus by mid-2022. The partnership with students will be like “quid quo pro.” An app will be developed to activate the scooters and they’ll get to use the scooters for little to no cost. In exchange, students agree to allow ScooterLab to use data collected from their rides for research and other scientific purposes.
Scooter data can pinpoint high traffic routes on campus. This could enhance safety by creating boundaries to separate pedestrians from scooter users. It could also help UTSA officials plan scheduled maintenance for highly trafficked routes. Lessons learned on how people and scooters can coexist at UTSA could also help other universities or municipalities manage scooter traffic and protect pedestrians.
