MAP data message (MAP)

data elements and frames comprising a message, the contents of which describe the geometry of a roadway intersection
NOTE 1 to entry: In the context of USDOT J2735™ SE Candidate, the MAP message provides the road geometry at an intersection.
NOTE 2 to entry: It is broadcast from the infrastructure to the vehicle.

misbehaviour

act of providing false or misleading data, operating in such a fashion as to impede other service recipients, or to operate outside of their authorized scope
NOTE 1 to entry: This includes suspicious behaviour as in wrong message types or frequencies, invalid logins and
unauthorized access, or incorrect signed or encrypted messages, etc., either purposeful or unintended.

PII

personal identification information; personally identifiable information

phase; interval; traffic signal phase

part of a traffic signal cycle during which, signal indications are stable and do not change
NOTE 1 to entry: In the SPaT message, the current timing value for the remaining interval time estimate, as well as the anticipated interval for yellow change (clearance) interval, is provided for each lane.
NOTE 2 to entry: Because signal interval times commonly change based on triggering events…

NOTE 1 to entry: In the SPaT message, the current timing value for the remaining interval time estimate, as well as the anticipated interval for yellow change (clearance) interval, is provided for each lane.
NOTE 2 to entry: Because signal interval times commonly change based on triggering events in many types of signalling systems, the value provided in the SPaT message may represent a minimal value that is extended and updated as the message is re-transmitted in real time.

physical security

safeguards to deny access to unauthorized personnel (including attackers or even accidental intruders) from physically accessing a building, facility, resource, or stored information (this can include simply a locked door, badge access controls, or armed security guards)
