BS ISO 14827-1:2005

This standard BS ISO 14827-1:2005 Transport information and control systems. Data interfaces between centres for transport information and control systems is classified in these ICS categories:

• 03.220.01 Transport in general
• 35.240.60 IT applications in transport

This part of ISO 14827 defines the format that should be used to document those end-application messages that are to be exchanged between and among central systems. The format is protocol-independent to the extent practical. For example, this one format can be used to define data exchanges that may apply to DATEX-ASN, CORBA, or other application protocols.

In general, each system can be viewed as consisting of the interfaces as shown in Figure 1:

Figure 1 System interface

Key

1	application interface
2	operator interface
3	communication interface
4	database interface
5	communications cloud
6	client system
7	server system

NOTE The communications cloud between the systems may be complex or simple.

This part of ISO 14827 deals only with the communication interface and is at a very high level. Other parts define how end-application messages can be exchanged using various application layer protocols.

While this part of ISO 14827 has been designed to meet the unique requirements of a TICS environment, it has been designed in a generic fashion and thus could be used for other data exchanges as well.
