NXP: five reasons to code for intelligent traffic lights

NXP Semiconductor works across a number of indusrty verticals, but the Dutch headquartered firm specialises in automotive semiconductors and automotive cybersecurity.

The firm has previous announced news of  Siemens using technology from NXP and Cohda Wireless for secure communication of vehicles with surrounding traffic infrastructure.

Vehicle-to-Infrastructure (V2I)

Today the company is focused on technology known as Vehicle-to-Infrastructure (V2I) for the growing field of intelligent traffic control.

The company says that the marriage of sensing, analysis, control, and communications holds great promise for Intelligent Transportation Systems (ITS).

According to NXP, Intelligent Roadside Units (RSUs) are most needed where vehicle traffic is highest and leading smart cities around the world will employ Intelligent RSUs to help smooth traffic flow and increase safety.

Five reasons for intelligent traffic lights

So why are intelligent traffic lights such a good idea? Think about it… these units will start to transmit information to car drivers ahead of their approach so that the driver won’t have to guess whether the light is about to change and ‘hit the gas’ for an extra spurt of speed.

  1. Safety: drivers will no longer ‘bolt’ to try and make lights before they change because they will be informed in-car as to when the light will change.
  2. Cost: drivers can drive more smoothly, using less petrol because they know more about the road ahead of them.
  3. Congestion: smoother traffic patterns and more even speed patterns cause less traffic congestion.
  4. Stress: a more controlled driving experience is a safer less stressful experience.
  5. Ecology: drivers running more effeciently will burn less fuel and the planet thinks that that is a good thing.

Vulnerable Road User Warnings

In the near future we can use these technologies not just to provide traffic flow optimization directions; we will also be able to tie in cloud-based analytics depending on how much information we have on individual drivers and create so-called Vulnerable Road User Warnings (VRUWs).
