The Use of Satellite Technology in Road Management

Valerann together with Excelerate technologies are developing a match-funded project by the European Space Agency. This project, dubbed ITS Equant, was designed to introduce specific space and satellite technologies to the Traffic Management and Intelligent Transportation Systems industries. Throughout the project Valerann will work with Excelerate, and with the support of the Satellite Applications Catapult, to integrate satellite communication, GPS RTK hardware, and geo-spatial based algorithms into the Valerann Smart Road System.

It may not be common knowledge but, the majority of our roads have neither the resources nor the traffic volumes to enable and justify spending millions of dollars in fibre optic communications. Some of these roads can fall back onto cellular technology. With 5G supposedly around the corner, such wireless connectivity may not fall too short of the bandwidth / vehicle that fibre offers to busier roads. Unfortunately, many roads will not have 5G for the foreseeable future. Indeed, many roads do not even have stable 4G or any cellular coverage. The National Infrastructure Commission recently released a report that concluded that 36% of highways in the UK do not have full 4G cover and 17% of such roads have no cover at all.

These roads and their users can still benefit greatly from data connectivity services: traffic would be safer, congestion could be managed, and future connected and autonomous vehicles could operate more efficiently. These are the first roads that would benefit from satellite-enabled ITS. Satellite connectivity could connect control centres and emergency responders to sensors in the field and data from vehicles to learn of risks and incidents that must be managed in real time. Likewise, down the road, such connectivity could be leveraged to inform connected vehicles of events downstream that would otherwise remain unknown until the last moment.

The main topics discussed are
1) What is the importance of data when managing roads?
-- What are the use cases now
-- What are the future use cases
-- What type of information is the most relevant for each use cases
-- Is real-time information a must have for road operators?

2) What are the main challenges of getting data?
-- Collection - What sensors / methods we use and where?
-- Accuracy - how accurate is the data in terms of measurement and location?
-- Connectivity - once you collected accurate information, how do you transfer it back to today's road connection, fiber optics, radio communication? What are the implications? V2I/V2X/I2V
-- latest trends and latency, bandwidth, cost

3) How can we use satellite technology to tackle these challenges?
-- Accuracy - GPS real location of events
-- Connectivity - (a) less infrastructure (b) in 17% of highways not connected via cellular network
-- Collection - Use low-energy/low-bandwidth sensors
-- How do you think road operators will view this possibility? Have they considered it before? Is it something new and useful or, on the contrary, is it something they would not use?
