Japan is bolstering its autonomous driving ambitions with a new project to be formally introduced Wednesday to expand the use of self-driving vehicles in more than 40 locations around the country by 2025.

The "Road to the L4” project aims to popularize advanced mobility services including Level 4 autonomous driving, wherein vehicles can operate without a human at the wheel. It will include demonstrations of the technology to promote acceptance and understanding, according to the Ministry of Economy, Trade and Industry. One of the goals is to help revitalize communities.

"People including the elderly don’t have ways to get around in rural areas,” said Tatsuki Izawa, an assistant manager in the ministry’s autonomous driving division. "If there are city-circular autonomous buses, they will be able to go shopping and have outings.”
