  The connected vehicle data (CVD) is one of the most promising emerging
mobility data that greatly increases the ability to effectively monitor
transportation system performance. A commercial vehicle trajectory dataset was
evaluated for market penetration and coverage to establish whether it
represents a sufficient sample of the vehicle volumes across the statewide
roadway network of New Jersey. The dataset (officially named Wejo Vehicle
Movement data) was compared to the vehicle volumes obtained from 46
weight-in-motion (WIM) traffic count stations during the corresponding
two-month period. The observed market penetration rates of the Movement data
for the interstate highways, non-interstate expressways, major arterials, and
minor arterials are 2.55% (std. dev. 0.76%), 2.31% (std. dev. 1.07%), 3.25%
(standard deviation 1.48%), and 4.39% (standard deviation 2.65%), respectively.
Additionally, the temporal resolution of the dataset (i.e., the time interval
between consecutive Wejo vehicle trips captured at a given roadway section,
time-of-day variation, day-of-month variation) was also found to be consistent
among the evaluated WIM locations. Although relatively low (less than 5%), the
consistent market penetration, combined with uniform spatial distribution of
equipped vehicles within the traffic flow, could enable or enhance a wide range
of traffic analytics applications.
