Dissemination goes hand in hand with data collection. The aim is to present information to different types of users: Both the general public (user, traveller, internet user) and professional users (drivers, operations officers etc.).
This section refers to the different products and systems used to disseminate information, whatever the channel used (this is discussed in the section Transmission / Telecoms).
The section is organised by means of dissemination:
- stationary terminals: PC, internet station, interactive terminal
- mobile terminals: Sat Nav, smartphone, on-board terminals
‘Passive’ dissemination (broadcast):
- voice: telephone, speakerphone
- displays: Variable message signs, displays in stations, on-board displays.
The means of dissemination often use telecommuncations technology and are specialised (general public, professionals, public transport, traffic, freight etc.).
Dissemination is often the main cost item in the budget for deploying an intelligent transport system, as the processing of the data is all done using software and therefore often costs less than the cost of the equipment in the field.
For many ITS applications, the aim is to provide information via a range of means, which implies a certain standardisation regarding how this information is transferred.
ITS applications are increasingly accessed via commonplace terminals (PCs via the internet), however interactive terminals are still required for sales on the ground.
Paper supports are still important for disseminating information (many sites make timetables and network maps available as downloads). Today however, these can be considered as by-products of information technology media

This is certainly the type of dissemination which has developed most rapidly in recent years, mainly due to the success of the mobile phone (and mobile internet use).
The satnav market has plateaued but is still expanding, notably to keep up with changes in on-board platforms and adapt in order to conform to the needs of freight transport.
Specialised terminals are deployed to meet a range of specific needs (more robust terminals for emergency response staff, terminals for ticket inspectors etc.).
Despite information being relayed via mobile phones, different types of VMS continue to be deployed along roads and motorways. The public transport displays at stations, hubs and on-board vehicles are changing rapidly with the general deployment of real-time information on public transport.
Finally, urban advertising billboards can also be used as a means of disseminating transport information.
