Lessons Learned & Issues from
Test Beds – Technical (Cont.)
§Better change management and proper documentation of hardware
and software is required
§Need management application for startup/shutdown of RSEs
and the ability to log and retrieve data
§VISSIM Hardware-in-the-loop simulation environment to support
development testing would be a useful tool
§Federal changes to standards and requirements
drastically impact ability to deploy operational systems.
§Interpretation of standards still differs amongst system
designers which adversely affects interoperability.
§Existing back office systems (GIS platform/mapping capabilities,
system health and status, safety data feeds) require
modification/enhancement to work in a connected vehicle
environment
§Agreement on inter-system interfaces is necessary
