AI Traffic Systems Test in Lakewood, San José Cities

Atlanta, GA — Two U.S. municipalities have rolled out artificial intelligence-based traffic monitoring systems in separate efforts aimed at collecting transportation data and responding to road safety issues.

In Lakewood, Colo., officials have installed edge AI sensing technology at intersections and mid-block areas identified as high-risk sites.

The system is designed to monitor vehicle and pedestrian movements as part of a broader traffic safety program.

The system operates in various lighting and weather conditions as part of the city's traffic safety program, which aims to reduce collisions.

San José, California, is conducting a pilot program through its Department of Transportation to gather continuous traffic data using AI sensing equipment.

The system records vehicle counts, speeds, directional flows, pedestrian activity, and bicycle usage.

Sony Semiconductor Solutions Corporation, the technology provider for both deployments, reported that initial evaluations in San José showed an accuracy rate of over 95 percent in directional traffic flow tracking.

Traditionally, transportation studies rely on temporary data collection over several days.

The new systems are designed to provide ongoing monitoring.

In Lakewood, the system supports the city’s Vision Zero safety objectives. In San José, officials plan to use the collected data to inform transportation planning and infrastructure investments.

Officials in San José stated that the technology could eventually be utilized for other municipal purposes, such as curb space management and detecting illegal dumping.

Sony demonstrated both municipal systems at the ITS World Congress, held from August 24 to 28 in Atlanta.

“These systems help cities respond to changing transportation patterns,” said Yu Kitamura, senior business development manager at Sony Semiconductor Solutions America.

Sony describes the technology as an open platform designed to work with a range of equipment providers.

The company identified nine partner organizations involved in the deployments: AglaiaSense, Gamax, Green Ideas Technology, Irida Labs, Itron, Modii, Nota AI, Synapse ITS and umojo.
