Customer Story: Purdue University

How are you understanding traffic and driving events on U.S. roadways? Our customer, Purdue University and their Joint Transportation Research Center team are using Wejo’s connected car data to improve the way they understand mobility to help cities and states make decisions.

“Connected vehicles know more about road infrastructure than many agencies do. Wejo has been a strategic partner with Purdue in developing big data processing techniques and use cases that can be scaled nationally,” said Darcy Bullock, the Director of the Joint Transportation Research Center at Purdue University. Darcy is also a professor at the Purdue University School of Engineering.

What specific aspects of Wejo connected car data does Purdue University rely on the most? Vehicle speeds to see slow downs and identify safety hazards and events like hard braking and hard acceleration – with very high precision, they report being able to identify areas on the road to improve safety almost immediately.

The benefits Purdue sees in Wejo connected car data:

  • Data volume: Purdue is using the biggest data asset of its kind that provides nationally scalable insights
  • Privacy and speed: Privacy by design and quickly available through Wejo real-time dashboards and low latency data point reporting
  • Cost savings: Utilizing cloud data with no need for traditional infrastructure investments
  • Scalability: Traffic performance measures at scale across urban areas and entire states
  • Heightened Safety: High fidelity characterization of construction work zone operations and hard braking

Agencies are very focused on how they can collect high quality data at the lowest possible cost – Purdue University has found that it makes no sense to have personnel out driving corridors collecting data, if they can pull that data in from Wejo connected data sources and get in many cases much better insights -- its cheaper and they get better quality data.

In just the state of Indiana, there were approximately 10.9 billion GPS positions and 7 million hard braking events from Wejo’s connected car data during August 2020. Bringing that data in 24/7, they are able to keep the pulse on the heartbeat of driving networks in various states. Before Purdue had this data, they report waiting months or even years to identify emerging safety problems based on crash data. With Wejo data, they can now see emerging problems quickly to improve safety.

“I personally like measuring things instead of modelling, and the exciting attributes of the Wejo data set are that the data allows us to directly measure traffic performance in real-time and make decisions in minutes, hours or days,” said Bullock.
