As congestion in the city is becoming a major problem cities are turning to advanced technologies to improve the safety of drivers and reduce wasted energy. This will help save time for both passengers and drivers, lower emissions, and reduce traffic congestion.

The technology behind it is based on hardware and software. The former is the executing subcomponent, while the latter is the command and control center. Both are equipped with the latest technology for sensing and processing for example, like ANPR (automotive plate recognition), which captures data about vehicles’ movements and detects road signs.

Depending on the type of solution, smart traffic lights can either process data on the device or send technologytraffic.com/2021/07/08/generated-post-2/ the data to a cloud storage. This type of solution allows for more sophisticated modeling and analysis to reduce traffic congestion and align schedules of public transport. This way, they can cut the average travel time by 25%, cut down signal wait times by 40%, and decrease emissions by 20%, according to Carnegie Mellon University.

A smart traffic light system, in addition to reducing the delays of traffic signals and improving pedestrian flow and the flow of micromobility vehicles like ebikes or electric scooters. They’re not able to conform to the traditional traffic law regarding preemption of signals. In London, for example, e-scooter crashes increased 2800% in the first quarter of 2021, therefore it is crucial to include them in traffic light controls.
