LTE based driver notification system tested in Finland
Technology demonstration in Helsinki the prelude to a two-year pilot program for using 4G/LTE mobile networks for Cooperative Intelligent Transport Systems.
HERE has completed a successful initial technology demonstration of the traffic information system it will pilot in Finland over the next two years.
In a small-scale test conducted on roads in the Greater Helsinki area, the system performed well in distributing targeted notifications about road hazards and conditions to relevant vehicles at low latencies, according to VTT, the Technical Research Centre of Finland, which carried out a technical assessment. HERE is now moving onto the next phase of the pilot, which from Spring 2016 will cover three major highways in southern Finland.
The basis of the system is to create a Cooperative Intelligent Transport System (C-ITS) which runs on a 4G/LTE mobile network. It’s cooperative because it engages vehicle-to-vehicle and vehicle-to-infrastructure (V2x) communications technology to gather and distribute information about conditions and hazards in a “coorperative” environment with network endpoints communicating with each other.
To achieve this, it makes use of standard and commercial networks as well as location cloud and data analytics from HERE to connect vehicles and traffic management centres in an intelligent system. The aim is that drivers can report road hazards and have an increased awareness of the road, such as where specifically there might be black ice or an animal on the road, sudden traffic build-up or an accident.
One of the advantages of using the mobile network infrastructure on such a project is the elimination of roadside infrastructure from the equation. Dedicated Short Range Communications systems are not needed in such an implementation. Instead, HERE’s approach centres on how standard and commercial mobile networks can underpin the concepts of ITS where data from vehicles and connected road infrastructure could be gathered, analysed, enriched and distributed back to vehicles and infrastructure at sub-second rates.
The Finnish traffic agencies selected HERE in June this year to lead the pilot and is now working with traffic information management service company Infotripla on the implementation of the pilot starting next year.
HERE and VTT are discussing how such technologies could lead to the creation of an ITS corridor using cooperative technologies across Norway, Denmark, Sweden and Finland.
