VIDBE-Q Volume 63 Issue 4
CMU is collaborating with Rapid Flow Technologies, the commercial supplier of the
surtrac technology.
The project plan includes field test experiments of the PedPal app by potential
users from the local disability community at intersections within the current Pittsburgh
surtrac deployment. Both BAH and Diyunu Consulting will assist in the experimental
setup and evaluation of test results, and the City of Pittsburgh has agreed to allow
access to relevant City intersections. The Port of Allegheny County has also pledged in-
kind support aimed at equipping buses that move through the test bed area with DSRC
onboard units, to enable future testing of the advanced capability to synchronize
pedestrian and bus arrivals at nearside bus stops.
Conclusions and Future Work
Current work is expanding the PedPal prototype to enable real-time tracking of
the user's progress during crossing and dynamic extension of the green time when
circumstances warrant. In August 2018, a field test of the technology involving
volunteers from the local Pittsburgh disability community is planned at one or more
intersections within the current surtrac connected vehicle test bed in the Pittsburgh East
End. In Year 2 of the project, the PedPal prototype will be refined based on feedback
from this initial evaluation, and the app will be further expended to provide mobility
enhancing capabilities.
