The volume of road traffic in Japan is forecasted to decrease steadily from 2024 to 2028. The numbers show a gradual decline from 7.8 million vehicle-km per motor vehicle in 2024 to 7.53 million in 2028. Compared to 2023, which was at a similar level to 2024, this indicates a downward trend. The year-on-year variations highlight a consistent reduction in traffic volume, averaging a decline of approximately 0.7% annually over this period. This reflects a Compound Annual Growth Rate (CAGR) that confirms the diminishing trend in traffic volume over these years.
Future trends to watch for include the impact of demographic changes, such as Japan's aging population and potential policy shifts encouraging public transport and sustainable vehicle use. Additionally, technological advancements in autonomous and electric vehicles could also influence traffic volumes and patterns in the coming years.
