TOKYO (AP) — Japan is planning to build an automated cargo transport corridor between Tokyo and Osaka, dubbed a “conveyor belt road” by the government, to make up for a shortage of truck drivers.

The amount of funding for the project is not yet set. But it’s seen as one key way to help the country cope with soaring deliveries.

A computer graphics video made by the government shows big, wheeled boxes moving along a three-lane corridor, also called an “auto flow road,” in the middle of a big highway. A trial system is due to start test runs in 2027 or early 2028, aiming for full operations by the mid-2030s.

“We need to be innovative with the way we approach roads,” said Yuri Endo, a senior deputy director overseeing the effort at the Ministry of Land, Infrastructure, Transport and Tourism.

Apart from making up for a shrinking labor force and the need to reduce workloads for drivers, the system also will help cut carbon emissions, she said.

“The key concept of the auto flow-road is to create dedicated spaces within the road network for logistics, utilizing a 24-hour automated and unmanned transportation system,” Endo said.

The plan may sound like a solution that would only work in relatively low-crime, densely populated societies like Japan, not sprawling nations like the U.S. But similar ideas are being considered in Switzerland and Great Britain. The plan in Switzerland involves an underground pathway, while the one being planned in London will be a fully automated system running on low-cost linear motors.

In Japan, loading will be automated, using forklifts, and coordinated with airports, railways and ports.

The boxes measure 180 centimeters in height, or nearly six feet, and are 110 centimeters, or 3.6 feet, by 110 centimeters in width and length, about the size of a big closet.

The system, which is also intended for business deliveries, may be expanded to other routes if all goes well. Human drivers may still have to do last-mile deliveries to people’s doors, although driverless technology may be used in the future.

Japan’s shortage of truck drivers is worsening due to laws that took effect earlier this year that limit the amount of overtime drivers can log. That’s seen as necessary to avoid overwork and accidents and to make the jobs tolerable, but in Japanese logistics, government and transportation circles, it’s known as the “2024 problem.”

Under current conditions, Japan’s overall transport capacity will plunge by 34% by 2030, according to government estimates. The domestic transport capacity stands at about 4.3 billion metric tons, almost all, or more than 91%, by trucks, according to the Japan Trucking Association.

That’s a fraction of what’s moving in a massive country like the U.S. About 5.2 trillion ton-miles of freight are transported in the United States each year, and that’s projected to reach more than 8 trillion ton-miles of freight by 2050. A ton-mile measures the amount of freight shipped and how far it’s moved, with the standard unit being one ton being moved one mile.

Demand for deliveries from online shopping surged during the pandemic, with users jumping from about 40% of Japanese households to more than 60%, according to government data, even as the overall population keeps declining as the birth rate falls.

As is true in most places, truck drivers have tough jobs requiring them to be on the road for days at a time, work that most jobseekers find unappealing.

In recent years, annual fatalities from delivery trucks crashing on roads have hovered at about 1,000 deaths. That’s improved from nearly 2,000 deaths in 2010, but the Trucking Association, which groups some 400 trucking businesses and organizations in the nation, would like to make deliveries even safer.

The association is also urging consumers to hold back on delivery orders or at least bundle their orders. Some industry experts are urging businesses to limit free delivery offers.

Trucks carry about 90% of Japan’s cargo, and about 60% of Japan’s fresh produce, like fruits and vegetables, come from distant places requiring trucking, according to Yuji Yano, a professor at the Ryutsu Keizai University, which is funded? by deliveries giant Nippon Express Co., now called NX Holdings, and focuses on economics and liberal arts studies, including trucking problems.

“That means the 2024 problem isn’t just a transportation problem but really a people’s problem,” Yano said.
