Imagine you’re driving and an animal or jaywalking pedestrian crosses the road ahead. The lane flashes a warning and changes colour, telling you to slow down. If an accident does happen, the road system itself sends a signal to authorities, and if there’s any damage to the asphalt, the road heals itself.
What might seem like something ripped from the world of Tron is not that far from reality.
As you’ll discover in this article, smart road technology development is well underway and, in some cases, already in early stages of testing. As experts in car insurance, we were curious to know how this could impact the way we insure our cars in the future.
Given smart road technology is still in development and not yet legally in use within Australia, there is no need for car insurance policies that cater to this market. However, as the technology continues to improve, there is certainly a chance we could see autonomous vehicles and other smart road components in use on our roads, somewhere down the line. If that comes to fruition, there could be some changes to the cost of insurance, given the value of specific vehicles could vary based on their ability to interact with smart road networks, for example.
But for now, let’s see how smart road networks could impact an existing policy.
While an LED future-scape with all roads being covered in screens and lights sounds cool, traditional asphalt may still be necessary. One of the downsides is that once you build it, you still have to repair it – but what if the road could repair itself?
There are a couple of ways of achieving a self-repairing road:
This technology works by heating or charging the road, causing sections of the asphalt to melt, reform and establish new bonds that remain just as strong as it was previously.
It’s estimated that if the entire planet’s road network could self-repair, it would reduce global emissions by 16% and lower infrastructure spending by 32%.25
Mixing steel wool with asphalt and using heat induction or microwaves is a promising method, with tests showing that even asphalt mixes including 1% steel fibres yield good results.26 This technology is being trialled in different parts of the world, including the Netherlands and China – the heating induction is also being tested in China as a way of melting snow.27
By utilising sensors, the road itself can determine whether or not it needs repairs. The road system can then engage its self-repairing mechanism, which saves on the amount of roadwork required, thus reducing congestion.
Self-healing roads likely won’t be able to be driven on while they repair themselves, so some lane closures and roadworkers will still be required to help guide traffic, though ideally at a reduced level. As the road is heated and reformed, repairs can take roughly three hours (depending on conditions) to fill cracks and solidify.28
Several of these smart road technologies can work in unison, such as solar roads with LEDs guided by smart VR2X systems. Self-repairing roads could sit above a bed of piezoelectric crystals to get even more functionality out of the world’s road network.
While these smart road technologies are still in development, and it would take a lot of work to add this technology to existing roads, a futuristic science-fiction vision for how we get around gets closer every day.
Where we’re going, we very much need roads, and cars to drive on them. You can review car insurance with us for free, in minutes, using our Australian car insurance comparison service.
