Air Quality

Poor air quality is the biggest environmental threat to health in the UK with up to 36,000 deaths a year attributed to long-term exposure (Public Health England, March 2019). The Environment Audit Committee has estimated that total health costs, due to air pollution, range between £8.5 billion and £20.2 billion a year.

Utilising intelligent signage to influence driver behaviour and increase the attractiveness of active travel (walking and cycling), by improving safety and comfort, can support the improvement in air quality.

We have supplied variety of solutions from Parking / Route Guidance to Overheight Vehicle Detection (OVD) and Hazard Warning, all of which help to reduce congestion and increase safety. In turn, these solutions support the reduction in air pollution. In addition, we have recently supplied LED message signs for the Birmingham Clean Air Zone (CAZ). Our fixed and mobile solutions also support the development and increased use of active travel infrastructure – more cycling and walking not only benefits the environment but also health and wellbeing.

More recently, with the implementation of air quality sensors, we can publish air quality levels on our intelligent signage to help raise awareness and encourage changes in behaviour.

Coeval is a specialist in robust, LED road sign-based systems that advise, inform, and educate and are:

  • more easily noticed by drivers than static signs
  • visible in all conditions, including at night
  • remotely controllable using our Cloud-based software
  • flexible to your needs – displaying different speed limits / messages as required
