  With the rapid increase in ride-hailing (RH) use, a need to better understand
and regulate the industry arises. This paper analyzes a year's worth of RH trip
data from the Greater Chicago Area to study RH trip patterns. More than 104
million trips were analyzed. For trip rates, the results show that the total
number of trips remained stable over the year, with pooled trips steadily
decreasing from 20 to 9 percent. People tend to use RH more on weekends
compared to weekdays. Specifically, weekend RH trip counts (per day) are, on
average, 20 percent higher than weekday trip counts. The results of this work
will help policy makers and transportation administrators better understand the
nature of RH trips, which in turn allows for the design of a better regulation
and guidance system for the ride-hailing industry.
