‘Core’ system (CorSys)

combination of enabling technologies and services that will provide the foundation for the support of a distributed, diverse set of applications/application transactions, which work in conjunction with ‘External Support Systems’ such as ‘Certificate Authorities’; the system boundary for the core system is not defined in terms of devices or agencies or vendors, but by the open, standardized…

combination of enabling technologies and services that will provide the foundation for the support of a distributed, diverse set of applications/application transactions, which work in conjunction with ‘External Support Systems’ such as ‘Certificate Authorities’; the system boundary for the core system is not defined in terms of devices or agencies or vendors, but by the open, standardized interface specifications that govern the behaviour of all interactions between core system users

acceleration

rate of change of velocity of an object with respect to time
NOTE 1 to entry: Acceleration is a physical vector quantity; both magnitude and direction are needed to define it.
The unit of the scalar absolute value (magnitude) of acceleration is measured in the international system of units
as metres per second squared (m/s2).

active manoeuvre

traveller paths (vehicles, pedestrians, bicyclists, etc.) that are allowed and have the right of way to enter and move through the path
NOTE 1 to entry: This term supersedes allowed movements which meant, in the context of this document, the directions of manoeuvre that are legally allowed at a specific point in time based upon the state of the intersection signals.
