V2ROADS' V2X Smart Core (V2SC) software effectively enables the opportunities provided by V2X technology. V2SC software is installed on vehicle road side units (RSU) and significantly improves road safety, traffic efficiency, and additional options for autonomous driving.

applications provided by V2X Smart Core:
The RLT service is an infrastructure service designed to transmit a road network map (RNM). The RNM includes traffic, parking spaces, pedestrian crossings, road intersections, traffic signs, etc.
In the RNM fragment example below, an area of road infrastructure describing the intersection of traffic lanes is shown

Road and lane topology
The figure shows an RNM example. Each entrance to the intersection (blue lanes) has an exit lane (red lanes). RLT service allows drivers to identify the correspondence between the messages about the traffic lights phase (SPATEM) and the specific direction of traffic that is controlled by this traffic light (black lines).
(RLT service)
The TLM service is an infrastructure service designed to transmit messages in relation to the phasing of traffic lights (SPATEM).
The TLM service informs road users in real-time about: the traffic light operation mode, permitted manoeuvres, priority traffic directions at regulated and unregulated intersections, etc.

Traffic light manoeuvre
The figure above shows a TLM service example. The lines in the figure describing permitted (green dotted lanes) and prohibited (red lanes) manoeuvres are highlighted in a specific color, depending on the status of the traffic light signals.
(TLM)
The IVI service is an infrastructure service designed to manage the creation, transmission, and reception of IVIM messages. IVIM messages contain information about mandatory and advisory road signs, such as situational speed warnings, roadworks, etc. IVIM messages provide information about physical road signs, such as static or variable road signs, as well as virtual signs.

The application provides the driver with information about dangerous situations arising whilst the vehicle is moving.
It supports the following scenarios:
It supports the following scenarios:
Road hazard signaling
(RHS application)
This scenario makes it possible to warn the driver about approaching roadworks hazards in time, through the vehicle's HMI (Human Machine Interface), so the driver can choose a suitable speed to exercise control of the vehicle and prevent possible collisions with workers/obstacles when entering the roadworks area.
Roadworks
This scenario is used on roads prohibited for pedestrians (highways, expressways, etc.) and warns drivers about their presence through the following channels:
1) automatically – when the vehicle automatically detects that a passenger has exited the vehicle:
2) in manual mode – when the alert is triggered by the passenger himself on leaving the vehicle.
A notification is displayed on the vehicle's HMI on approaching the event and the distance to the hazard. After the vehicle has passed the dangerous section of the road, the warning on the HMI is disabled.

A notification is displayed on the vehicle's HMI on approaching the event and the distance to the hazard. After the vehicle has passed the dangerous section of the road, the warning on the HMI is disabled.
Human presence on the road
If the vehicle's trajectory intersects with a hazardous location (temporary or permanent), then the vehicle's HMI displays a notification as it approaches the location and the distance to it. After the threat of an emergency ceases, the warning on the HMI is disabled.
The implementation of this scenario allows drivers to respond on time to the threat of a potential emergency.
