AVSC Best Practice for ADS Remote Assistance Use Case

2023-11-28
CURRENT
AVSC-I-04-2023
Automated driving system-dedicated vehicles (ADS-DVs) can handle a wide variety of circumstances they might encounter on the road. When circumstances are encountered that exceed ADS design capabilities, the ADS is designed to bring the vehicle into a minimal risk condition (MRC). When an ADS-DV encounters these conditions—identified as “triggers” within this best practice—they can request remote assistance (RA) from a remotely located human operator. RA involves the provision of guidance, suggestions, or recommendations to a vehicle from a remote location, without direct control of the vehicle. RA has emerged as a useful tool in supporting the operation of an ADS. It can complement the capabilities of ADS-DVs and improve overall system performance and utilization, particularly in situations that exceed ADS design capabilities. This best practice provides guidelines for integrating remote assistance within the context of ADS.

Using Radio Technical Commission for Maritime Services Corrections in a Consumer-Grade Lane-Level Positioning System for Connected Vehicles

2023-05-08
It consists of a single-frequency real-time kinematic (RTK)-capable GNSS receiver onboard the vehicle, which utilizes Radio Technical Commission for Maritime Services (RTCM) differential corrections transmitted over dedicated short-range communications (DSRC) by the roadside infrastructure. Tests on a moving vehicle show that this system could provide lane-level accuracy over 95% of the time in open-sky conditions. ...These tests also show the DSRC to be an effective means of disseminating RTCM corrections, given the intersection spacings and communication ranges in the test.
