Smart Technologies for Traffic

Cities are shifting to smart technology for traffic to reduce energy waste and improve road safety, as traffic congestion in urban areas becomes a growing problem. This helps passengers and drivers save time, reduces carbon emissions, and reduces traffic jams.

The technology behind it is based on hardware and software. The former is the executing subcomponent, and it is used as the command and control center. Both are enhanced with modern sensing technologies and processing for example, like ANPR (automotive plate recognition) which collects data regarding vehicle movements and is able to detect road signs.

Depending on the solution, smart traffic lights can either process data on-device or transfer it to a cloud location. The latter offers more sophisticated analysis and modeling to prevent traffic congestion and to harmonize public transport schedules. In this way, they can reduce average travel times by 25%, reduce time to signal by 40%, and reduce emissions by 20 percent, according to Carnegie Mellon University.

In addition to the reduction of traffic signals’ control delays, a smart traffic light system can enhance the flow of pedestrians and micromobility vehicles like electric bikes and e-scooters. They’re not able to conform to traditional traffic signal preemption laws. In London, e-scooter accidents increased by 2800% in the first half 2021. Therefore, it is crucial to include them in traffic lights controls.
