Embed static info (i.e. enhanced map data, speed limit, curvature, asphalt characteristics, etc.) to be transmitted to the vehicle, that are programmed after deployment and reprogrammed when the use of the road changes or during road works.
Receive dynamic info (i.e. TMC messages), process and transmit them to the passing vehicles, to be offered to the driver/rider in a personalised manner.
Measure dynamic environmental parameters (like temperature, humidity, water, ice, oil, smoke) and accurately estimate each vehicle’s friction coefficient (through road sensors data fusion with vehicles’ intelligent tyres’ info).
Sense passing vehicles, including non-equipped ones, measure the transit time, speed and lateral position in the lane, provide basic classification of the vehicle type and, thus, offer key road load & circulation data to the TMC.
Sense pedestrian crossings, work zones, railway crossings and other critical areas and warn the driver/rider well ahead of them.
Enable high accuracy and low cost automatic parking/tolling/insurance policies.
Define and manage lane-level virtual corridors for automated driving.
Approach for Equipped Vehicles
Road Strip to Vehicle
Strip-to-Vehicle solution for equipped vehicles:
- ORU embeds the on-road sensors (e.g. humidity, ambient light detector, temperature, etc.), which are wired on a IEEE 802.11p enabled micro-controller and communication module capable for interfacing with the road sensors (e.g. through a GPIO h/w interface).
- One ORU is installed per lane of the road.
- Data fusion is processing incoming data from the road, the tyres/friction coefficient estimation module & the CAN Bus.
- Decision making is running in the OVU & notifications /warnings /recommendations are sent to the on-board HMI (or the smartphone).
Equipped vehicle utilising info provided by the system to enhance its on-board systems reliability
TM applications are enabled through V2V communication between the equipped cars and the TMC floating cars (by use of the IEEE 802.11p standard).
TMC floating cars act as service providers by exhibiting their ability to connect to the TMC network and send coded messages to the appropriate FM radio broadcaster for transmission as a RDS signal within ordinary FM radio transmitters
Approach for Non-Equipped Vehicles & PTW’s
Road Strip to RSU to Vehicle
Strip-to-RSU-to-Vehicle” solution for non-equipped vehicles & PTW’s
- Transmission of the ORU captured data over the infrastructure-based TMC network through the base station node (RSU) wirelessly.
- OR by exploiting the V2V communication capabilities between appropriately equipped cars, and through the TMC network, by involving TMC floating cars.
- Communication between the ORU and the RSU is handled through a micro-controller with wireless communication capabilities (e.g. through IEEE 802.11b/g/n).
