  Real-time traffic and sensor data from connected vehicles have the potential
to provide insights that will lead to the immediate benefit of efficient
management of the transportation infrastructure and related adjacent services.
However, the growth of electric vehicles (EVs) and connected vehicles (CVs) has
generated an abundance of CV data and sensor data that has put a strain on the
processing capabilities of existing data center infrastructure. As a result,
the benefits are either delayed or not fully realized. To address this issue,
we propose a solution for processing state-wide CV traffic and sensor data on
GPUs that provides real-time micro-scale insights in both temporal and spatial
dimensions. This is achieved through the use of the Nvidia Rapids framework and
the Dask parallel cluster in Python. Our findings demonstrate a 70x
acceleration in the extraction, transformation, and loading (ETL) of CV data
for the State of Missouri for a full day of all unique CV journeys, reducing
the processing time from approximately 48 hours to just 25 minutes. Given that
these results are for thousands of CVs and several thousands of individual
journeys with sub-second sensor data, implies that we can model and obtain
actionable insights for the management of the transportation infrastructure.
