ISO/TS 19082 specifies data elements and data frames for messages exchanged between roadside modules and signal controllers, traffic management centres, and other roadside modules for expressing processed and statistical data. Roadside modules can generate data based on inputs from vehicle detectors and/or probe data transmitted by vehicles.
The data structure follows the framework specified in ISO 14817-1, and the data elements and data frames are described by description name, object identifier, definition, and data type following ISO 14817-1. The specifications of ISO/TS 19082 complement those from ISO/TS 19091 and other standards.
The roadside modules can be constructed in any manner using any architecture including the ITS station as described in ISO 21217, or other hardware and software constructs.
NOTE: ISO/TS 19082 does not address how the roadside module generates the data, it only addresses communication after receiving and processing raw data from one or more sources.
ISO/TS 19082 on roadside modules and signal controllers for signal control is useful for:
Signal controllers and traffic control centres optimize signal timings based on real-time traffic information for each approach. For example, signal controllers may extend the green time for an approach with a long queue. A roadside module can calculate vehicle volume, average speed, and queue length by utilizing data from vehicle detectors and probe information.
ISO/TS 19082 helps you by providing the data elements and data frames for communications between roadside modules and signal controllers, traffic management centres, and other roadside modules. The data elements and data frames are useful for optimizing local and coordinated signal operations.
ISO 22951 prioritization signal systems for emergency and public transport vehicles (PRESTO) specifies the message sets for signal system pre-emption and priority for transit vehicles including communications between roadside modules and signal controllers. ISO/TS 19082 complements PRESTO by defining message sets for traffic information that is useful for optimizing normal signal operations. Thus, signal controllers and traffic management centres can generate signal timings referring to the messages of PRESTO and ISO/TS 19082.
