Mayor Eric Adams and the New York City Department of Transportation (DOT) Commissioner Ydanis Rodriguez have introduced a new permit program designed to oversee the testing of autonomous vehicles in New York City.
The United Kingdom’s first fully electric self-driving bus began service on public roads from the Didcot Parkway railway station in June, reported the BBC.
How Inertial Systems and GNSS Availability Will Help
Self-driving cars in urban environments can be problematic. The required multi-sensor automated systems will include GNSS, but buildings block and reflect GNSS signals, reducing system availability and accuracy. Researchers from the Illinois Institute of Technology report on how inertial navigation systems coupled with wheel-speed sensors and vehicle dynamic constraints can help.
The mass introduction of self-driving cars onto public roads will require overcoming ethical challenges. As a society, we will have to agree on a uniform set of ethical codes.
