As urban traffic congestion becomes a major issue cities are turning to smart technology for traffic to increase road safety and reduce wasted energy. Among other things, this can help to cut down on time for passengers and drivers as well as reduce emissions and reduce traffic congestion.

The technology behind it is based on hardware and software. The first provides the executing component, while the latter is the command and control center. Both are equipped with the latest sensors and processing techniques for example, like ANPR (automotive plate recognition) which records data about the movement of vehicles and is able to detect road signs.

Depending on the type of solution, smart traffic lights may process data on the device or send it to a cloud location. This is a way to perform more advanced analysis and modeling to reduce traffic congestion and harmonize schedules of public transport. In this way, they can reduce the average travel time by 25%, reduce signal wait times by 40%, and lower emissions by 20 percent, according to Carnegie Mellon University.

In addition to decreasing traffic signals’ control delays, a smart traffic light system can also increase the flow of pedestrians as well as micromobility vehicles, such as electric scooters and e-bikes. This is because they’re not able to follow the traditional preemption rules. In London for instance the number of crashes involving e-scooters increased by 2800% during the first quarter of 2021, therefore it is essential to factor them into traffic light control.
