Beep, Inc. provided weekly data reports to Cary and the North Carolina Department of Transportation (NCDOT) that included the shuttle’s disengagements from autonomous mode.

This dataset is compiled from Beep, Inc.’s reports for the 13-week pilot period and includes each disengagement event and its reported cause.

The shuttle uses an Automated Driving System (ADS) to operate without a driver on a pre-determined, pre-mapped, fixed route. The system provides conditional automation, meaning that most driving functions and roadway monitoring are automated. The shuttle uses Light Detection and Ranging (LiDAR), cameras, and Global Positioning System (GPS) technology to know its location, where it is going, and what is happening around it. The shuttle is programmed to automatically disengage from autonomous mode and come to a complete stop when an obstacle is too close or when all required conditions for operation are not met. The system then prompts the attendant to take control until autonomous operation can resume. The attendant can also manually disengage from autonomous mode when deemed necessary.

NCDOT partnered with Cary to bring the Connected Autonomous Shuttle Supporting Innovation (CASSI) program to Bond Park. Please see Cary's article and NCDOT's CASSI webpage for additional information about the program.
