Smart Technologies for Traffic

Cities are shifting to smart technology for traffic to cut down on energy consumption and increase road safety traffic congestion in urban areas becomes a growing problem. Apart from that, it assists in reducing time for both drivers and passengers, lower emissions, and reduce traffic congestion.

The technology behind this is based on two main elements: Hardware and software. The first is the component that runs, and the second is the command and control center. Both are enhanced by advanced sensors and processing technologies, such as ANPR (automotive plate recognition) which collects data about the movement of vehicles and is able to detect road signs.

Based on the type of solution, smart traffic lights may process data on-device or transfer the data to a cloud storage. The latter is more sophisticated analysis and modeling to reduce congestion in traffic and align public transport schedules. In this way, they can cut the average travel time by 25%, cut the time between signals by 40%, and cut down on emissions by 20%, according to Carnegie Mellon University.

In addition to the reduction of traffic signals’ control delays, a smart traffic light system can also improve the flow of pedestrians and micromobility vehicles such as electric scooters and ebikes. They are unable to adhere to the traditional traffic law regarding preemption of signals. In London for instance the number of crashes involving e-scooters increased by 2800% in the first half of 2021. so it is important to consider them when determining traffic light control.
