1. WLTP-DTP-LabProcICE-132
Assessment of the loading ratio of light-duty commercial vehicles in Japan
Prepared by Japan

2. “Annual Statistics of Automotive Transport”
(published by Ministry of Land, Infrastructure, Transport and Tourism)
This statistics is aimed to find out the current status of transportation by passenger vehicles and commercial vehicles in Japan.
The total traffic volume and travel distance are estimated by asking the questionnaire to vehicle owners.
The results for light duty commercial vehicles are:
