Cities are adopting smart traffic technologies to reduce energy waste and improve road safety as traffic congestion in urban areas is becoming more frequent. This helps motorists and passengers save time, reduces emissions and delays in traffic.

The technology behind it is built on both software and hardware. The first is the subcomponent that runs, and the second is the command and control center. Both are enhanced with modern sensors and processing techniques tools, for instance ANPR (automotive plate recognition) that collects information about the movement of vehicles and is able to detect road signs.

Depending on which solution is utilised, data may be processed on the device by smart traffic lights, or sent to cloud. This type of solution allows for more sophisticated modeling and analysis to reduce congestion in traffic and to harmonize the schedules of public transport. In this way, they can cut the average travel time by 25%, cut down signal wait times by 40%, and cut down on emissions by 20%, according to Carnegie Mellon University.

In addition to reducing the time it takes to control traffic signals A smart traffic light system will also increase the flow of pedestrians as well as micromobility vehicles, such as e-bikes and e-scooters. This is due to the fact that they’re not able to comply with traditional traffic signal preemption rules. In London the e-scooter accident rate increased by 2,800% over the first half of 2021. It is therefore important to include them in traffic light controls.
