Interoperability has been achieved across all devices and vehicles participating in the Safety Pilot Model Deployment!
Another major
accomplishment in the SPMD is the interoperability testing. There were three
separate stages of interoperability testing in the Safety Pilot, conducted in
June, August, and December. Each stage focused on different functional
capabilities of the devices (i.e. BSM transmission, traveler information
messages/SPaT, and security functions). Each phase of the testing included
bench testing in a laboratory environment as well as field testing where the
devices were temporarily installed in vehicles and driven around the MD
environment.
The objectives of
this testing was to verify that these devices produced by different
manufacturers could work cooperatively together. Furthermore, this testing
was also able to provide additional information that can be feed back into
the USDOT requirements and industry standards for next generations of these
devices.
