Advanced Smart Mobility sought positioning technology for vehicular localization

Japan has recently faced a severe driver shortage in their public mass transportation systems. To solve this challenge, they are looking to create a smart public transportation system, including a significant component of autonomous buses and trucks.

To meet this challenge, Advanced Smart Mobility, in collaboration with the University of Tokyo, is conducting research on autonomous driving and intelligent transportation systems (ITS) geared toward large trucks and buses.

On-road autonomous driving has significant challenges. ASM teams needed to first understand how to build an application that responds accurately in multiple environments (urban, suburban and mountain areas). In order to perform correctly in those settings, the application needs to be stable and robust, while also capable of delivering accurate vehicular localization.

Precise positioning is also a significant challenge. With a long-standing relationship with Trimble, ASM selected their high-precision positioning technology (including RTK with VRS) to achieve the highest level accuracy. Many Trimble BX940 enclosures with BD940-INS inside, and Zephyr 3 Rover antennas are currently in use for this research and development program.
