In the coming years, the digitalisation of transport in general and ITS in particular
are expected to take a leap forwards. As part of the Digital Single Market Strategy,
the European Commission aims to make more use of ITS solutions to achieve a more
efficient management of the transport network for passengers and business. ITS will be
used to improve journeys and operations on specific and combined modes of transport.
The European Commission also works to set the ground for the next generation of ITS
solutions, through the deployment of Cooperative-ITS, paving the way for automation
in the transport sector. C-ITS are systems that allow effective data exchange through
wireless technologies so that vehicles can connect with each other, with the road
infrastructure and with other road users.
7.3.1 Telematics systems in process of ensuring the safety
in motor transport
Nowadays, the modern technologies are the subject of interest of science and
automotive industry. Wireless units will be installed in vehicles and probably also in fixed
locations such as near traffic signals and emergency call boxes along the road. Sensors
in the cars and at the fixed locations, as well as possible connections to wider networks,
will provide the information, which will be displayed to the drivers in some way. The
range of the radio links can be extended by forwarding messages along multi-hop paths.
Even without fixed units, information about fixed hazards can be maintained by moving
vehicles by passing it backwards. It also seems possible for traffic lights, which one can
expect to become smarter, to use this information to reduce the chance of collisions.
Further in the future, it may connect directly to the adaptive cruise control or
other vehicle control aids. Cars and trucks with the wireless system connected to their
