BS EN 16157-7:2018

What is BS EN 16157-7-  Common data elements in Intelligent transport systems about?  

BS EN 16157-7 specifies and defines component facets required to support the exchange and shared use of data and information in the field of traffic and travel. 

The component facets include the framework and context for data content, data structure and relationships, communications specification. 

BS EN 16157-7 is applicable to: 

• Traffic and travel information which is of relevance to road networks (non-urban and urban),
• Public transport information that is of direct relevance to the use of a road network.
• Traffic and travel information in the case of Cooperative intelligent transport systems (C-ITS).

BS EN 16157-7  establishes specifications for data exchange between any two instances of the following actors: 

• Traffic Information Centres (TICs)
• Traffic Control Centres (TCCs)
• Service Providers (SPs)

BS EN 16157-7 covers, at least, the following types of informational content: 

• Road traffic event information – planned and unplanned occurrences both on the road network and in the surrounding environment 
• Information about operator-initiated actions – including both advisory and mandatory measures 
• Road traffic measurement data, status data, and travel time data 
• Travel information relevant to road users, including weather and environmental information 
• Road traffic management information and information and advice relating to use of the road network 

BS EN 16157-7 specifies common informational structures, relationships, roles, attributes and associated data types required for publishing information within the DATEX II framework.  

Who is BS EN 16157-7- Common data elements in Intelligent transport systems for? 

BS EN 16157-7 on  DATEX II data exchange specifications for traffic management and information is useful for: 

• Traffic Information Centres (TICs)
• Traffic Control Centres (TCCs)
• Service Providers (SPs)

Why should you use BS EN 16157-7- Common data elements in Intelligent transport systems?  

BS EN 16157-7 helps the manufacturers with a commonly benefit set of data exchange specifications to support the vision of a seamless interoperable exchange of traffic and travel information across boundaries, including national, urban, interurban, road administrations, infrastructure providers and service providers. 

Standardization in BS EN 16157-7 is a vital constituent to ensure interoperability, reduction of risk, reduction of the cost base, promotion of open marketplaces and many social, economic and community benefits to be gained from more informed travellers, network managers and transport operators. 

BS EN 16157-7 includes the framework and context for exchanges, the modelling approach, data content, data structure and relationships, communications specification. BS EN 16157-7 is targeted to deal with the common data elements that are used in more than one publication. BS EN 16157-7 specifies reused structures and definitions of information that may be exchanged to convey information described in the other parts of this EN. The elements described in BS EN 16157-7 have their own namespace “Common”.
