Smart Technologies for Traffic

As urban traffic congestion becomes a major issue, cities are turning to smart technologies for traffic to improve the safety of roads and cut down on wasted energy. Among other things, this can help to cut down on time for both passengers and drivers and lowers emissions. It also helps reduce traffic congestion.

The technology behind it is based on software and hardware. The former is the subcomponent that executes, while the latter is the command and control center. Both are enhanced by sensors and processing techniques that include ANPR (automotive license plate recognition) which records data about vehicle movements and can detect traffic signals.

Depending on the solution employed, data can be processed on the device by intelligent traffic lights or transmitted to a cloud. The latter is more sophisticated analysis and modeling to stop traffic congestion and harmonize public transport schedules. According to Carnegie Mellon University, this could cut travel time by 25 percent, and wait times for signals are cut by 40% and emissions are reduced by 20%.

In addition to cutting down on traffic signals’ control delays, a smart traffic light system can also increase the flow of pedestrians and micromobility vehicles such as e-bikes and e-scooters. This is because they’re typically not able follow the traditional preemption rules. In London for instance the number of crashes involving e-scooters increased by 2,800% in the first half of 2021. therefore it is crucial to consider them when determining traffic light controls.
