Smart Technologies for Traffic

Cities are adopting smart traffic technologies to cut down on energy consumption and improve road safety as urban traffic congestion becomes a growing problem. This helps both drivers and passengers save time, reduces carbon emissions, and reduces traffic jams.

The technology behind this is based on two principal components: Hardware and software. The first is the subcomponent that executes, and the second is the command and control center. Both are complemented by advanced sensors and processing techniques that include ANPR (automotive license plate recognition) which records data about vehicles’ movements and is able to detect traffic signs.

Depending on the solution, smart traffic lights are able to process data on-devices or send it to a cloud location. This type of solution allows for more advanced analysis and modeling to reduce traffic congestion and coordinate the schedules of public transportation. In this way, they can cut the average travel time by 25%, cut down signal wait times by 40%, and lower emissions by 20 percent, according to Carnegie Mellon University.

A well-designed traffic light system as well as reducing the time it takes to get traffic signals, can also improve the flow of pedestrians as well as of micromobility vehicles such as e-bikes or e-scooters. This is because they’re typically not able adhere to traditional traffic signal preemption rules. In London the e-scooter accident rate increased by 2,800% during the first quarter of 2021. Therefore, it is important to include them in traffic lights controls.
