The Real Time Information Group (also RTI ) is an organization in the United Kingdom supporting the development of bus passenger information systems ; icts 85 members include local autorités , bus operators and system suppliers together with Representatives from the UK government and other key industry groups Such As ITS (UK) Travel Information Highway, and the UTMC Development Group (UDG). 
The main output of the group is guidelines, case studies and best practice documents.  These documents are produced by RTIG on behalf of its members, usually with the assistance of specialist working groups.
In 2000, when real-time information (RTI) systems were introduced to be considered by UK local authorities to provide passengers with up-to-the-minute passenger information, it was realised that cross-boundary bus services made it Imperative to coordinate projects around the UK. Technical and operational standards would be required. A group of local authorities and bus operators. And so RTIG was born.
Substantial government funding for projects around the UK, in particular from 2002 to 2004, provided an enormous boost to the development of RTI systems. The RTIG to reflect on its role, and in 2003 it was determined to recreate itself as a group. Equally importantly, it has maintained excellent links with central UK Government, from whom the Group continues to receive funding for work of national scope and importance.
The National RTI Strategy,  ratified in March 2007, establishes a framework for how industry and government need to work together to deliver benefits to passengers. RTIG’s role has, as a consequence, been expanded to cover all aspects of technology in public transport, from systems to support disabled travelers through to safety and security systems.
In 2002 the group produced the first UK RTI Survey, which surveyed the use of RTI technology by local authorities and passenger transport executives across England , as well as plans for the following two years. In 2004 the survey was extended to include Wales and in 2005 Scotland .
In order to reflect the widening deployment of bus-related technologies, the 2006 annual survey was re-branded as the ‘RTIG Passenger Transport Technology Survey’  and included questions on services for disabled travelers. Under the Disability Discrimination Act 2005 . The CCTV and other security technologies. The CCTV and other security technologies. The 2007 report is expected to be publicly available in the first quarter of 2008.
The annual survey provides details on:
- Number of RTI equipped buses in Great Britain
- Number of RTI signs in GB
- Use of audio equipment in GB
- Costs of implementing and maintaining RTI in GB
- Trends in the integration of RTI with UTMC technology
- The provision of information for disabled travelers in GB
- Passenger and driver security systems (on and off bus)
The majority of the documents, standards and guidelines produced by RTIG are done with the assistance of voluntary working groups. These working groups are made up of experts who lend their knowledge to particular projects. Examples of RTIG working groups include:
- Data Suppliers Working Group
- Shelter Implementation Working Group
- Disability Working Group
- On-bus architecture Working Group
- GPRS Interface Working Group
Working groups involve non-members where relevant; So, the Disability WG includes representatives of charities such as RNIB and Dogs .

RTIG involvement in international standards
RTIGs have been developed to support the development of a number of standards, including the Service Interface for Real Time Information (SIRI). RTIG has also developed a number of best practice guidelines .
