Objectives of the service

Roads use active traffic management technologies to detect incidents, respond to risks, prevent accidents, pinpoint traffic bottlenecks, reduce congestion and keep traffic flowing. The benefits are substantial: decreasing accidents by 35%, injuries and fatalities by 31% and congestion by 20%. Unfortunately, these technologies rely on expensive supportive infrastructure such as electrical and communication cables, making them prohibitively expensive at >£1M/KM. As a result, less than 4% of roads enjoy these benefits. Valerann has developed a wireless, solar-powered, multi-sensory solution to bring the benefits of traffic management to all roads, at just 20% of the cost of current solutions. By leveraging satellite communications and geo-positioning, the ITS Equant consortium aims to make Valerann’s technology more scalable and capable in roads where there is limited cellular connectivity. In doing so, the consortium will make the benefits of active traffic management available to all roads.

Users and their needs

Valerann’s users are organisations called road operators. These are often private organisations that are hired by local governments to maintain roads, monitor traffic, and respond to incidents. Their main objectives are to maximise traffic efficiency and safety, within their respective budgets.

The biggest challenge these operators face is getting reliable information about traffic in their network, so they can make decisions about where and how to respond to incidents when they occur. Specifically, they must:

  • Detect and verify incidents when they occur, and understand their precise location, time, severity, and context
  • Identify and mitigate major risks to traffic safety
  • Determine the location of traffic bottlenecks as they occur, before they turn into congestion
  • Stay within a budget so that their entire network can benefit from these capabilities, rather than just a select few roads

Service/ system concept

Valerann provides road operators with the precise real-time location and trajectory of every single vehicle on the road, down to 10cm resolution. Valerann uses machine learning and AI algorithms to identify traffic anomalies and classify them into specific incidents that require attention. For example, a vehicle breakdown will appear as a trajectory that slows down and veers towards the hard shoulder, eventually coming to a full stop.

Valerann deploys a grid of IoT sensors, which replace plastic or metallic road markers. These units detect vehicles passing in their vicinity. This information is wirelessly transmitted to a road-side gateway that then sends the information onwards, via satellite uplink, to Valerann’s cloud server. In the cloud, each stud is associated with a specific GPS RTK coordinate. Our algorithms then organise digital impressions of the many vehicles into the unique trajectories of each individual vehicle. 

Space Added Value

Space technology provides three main layers of value-addition:

  1. Expedited installation: Valerann’s algorithms today rely on an understanding of the distance between the sensors on the road. To ensure this is accurate, today (as part of the installation process) the exact location and distance is measured during installation. This creates a slower installation process that is very prone to error at scale, as contractors will be liable to measure incorrectly or record distances inaccurately. Using space technology, Valerann will enhance the installation process to digitally associate a precise GPS coordinate with each sensor as they are installed. In this way, the cloud will be able to calculate the precise location and distances between different sensors to inform its algorithms.
  2. Expanded coverage: As a default, Valerann’s system uses cellular connectivity to send information from the gateway to the cloud. However, many roads do not have stable cellular coverage: in the UK, 47% of highways lack stable 4G coverage and 17% of highways have no cellular reception at all. Satellite communication will broaden the use of Valerann’s system to include such roads that currently cannot access it.
  3. External interface: Valerann’s system is designed to inform decision-making by external stakeholders (external to Valerann). These include control centres, emergency response services, and (in the future) connected vehicles. These users require a standardised format to receive and transmit information of events. These formats rely on GPS coordinates. By instilling GPS coordinates into the basis of the system, it will enable Valerann to communicate and provide valuable info to all stakeholders

Current Status

Following a successful large-scale deployment of Valerann’s system in Ayalon Highways, Valerann has focused on sharing this success with multiple potential partners, who have shown interest in the solution. Valerann has deployed its first version of the Geo-accurate dashboard that integrates data from multiple sources onto a map component, highlighting the importance of GIS-based data fusion.

In parallel, the team has started testing different satellite communication modules with Valerann’s system to decide which module and protocol are best suited for the system going forward.

Valerann has registered to present its solutions in the IBTTA annual tech conference.
