Emerging connected vehicle (CV) data sets have recently become commercially
available that enable analysts to develop a variety of powerful performance
measures without a need to deploy field infrastructure. This paper presents a
several tools using CV data to evaluate the quality of signal progression.
These include both performance measures for high-level analysis as well as
visualizations to examine details of coordinated operation. With the use of CV
data, it is possible to assess not only the movement of traffic on the corridor
but also to consider its origin-destination (O-D) path through the corridor,
and the tools can be applied to select O-D paths or to all O-D paths in the
corridor. Results for real-world operation of an eight-intersection signalized
arterial are presented. A series of high-level performance measures are used to
evaluate overall performance by time of day and direction, with differing
results by metric. Next, the details of the operation are examined with the use
of two visualization tools: a cyclic time space diagram, and an empirical
platoon progression diagram. Comparing visualizations of only end-to-end
journeys on the corridor with all journeys on the corridor reveals several
features that are only visible with the latter. The study demonstrates the
utility of CV trajectory data for obtaining high-level details as well as
drilling down into the details
