In preparing for autonomous vehicles, agencies can make needed changes

By Chris Spahr and Chris McCahill The potential impacts of autonomous and connected vehicles on travel behavior and transportation system design have been the focus of much discussion and speculation, including at SSTI’s recent Community of Practice meeting held in Salt Lake City. While it is

Sit back, relax, and enjoy the drive: An update on autonomous vehicles

By Mary Ebeling Since we last wrote about driverless cars in December, several states have taken a detailed look at legislation to phase in operation of this new type of vehicle. These new laws focus on testing, safety, and operations. Conversations addressing the thorny issues around liability

Ann Arbor could become testing ground for network of driverless cars

By Chris McCahill While driverless cars seem to be a technological reality thanks to innovative leaders at Google, questions still remain as to their implementation and practicality. Researchers at University of Michigan hope to answer these questions by launching a citywide network of shared

The winding road to self-driving cars

By Bill Holloway This spring, the National Highway Traffic Safety Administration released a policy statement on automated vehicles, which offers guidance for states that are considering authorizing tests of driverless vehicles. It outlines NHTSA’s research program and provides an overview of

With continued testing success, governments are embracing connected and self-driving vehicles

By Bill Holloway The California state senate recently voted unanimously to approve Senate Bill 1298, which would establish safety and performance standards for self-driving, or “autonomous,” vehicles. The bill now goes on to the state assembly. Florida and Nevada have already enacted
