§Institutional
□Requires training for
engineering and staff to understand technology and system operation
□
§Technical
□DSRC Range from multiple
nearby RSE’s broadcasting MAP and SPaT data require OBE algorithms
to determine which MAP and SPaT is relevant
□Current BSM
specification doesn’t contain Mode information
□Current SSM (Signal
Status Message) doesn’t acknowledge all Signal Request Messages (SRM) – only
acknowledges one
§
§How to overcome
□Multiple MAP’s resolved
algorithmically
□Working with SAE DSRC
