Autonomous vehicles are no longer just a technology for the future. USDOT has issued its Future of Transportation-Automated Vehicles 3.0 guidelines and directions: https://www.transportation.gov/av/3
The current levels of Autonomous Vehicles are detailed below.
An automated vehicle uses a variety of sensors to collect data about the surrounding environment. Maps and GPS help to localize the vehicle. Onboard computers analyze the data collected by the sensors, as well as the mapping data, to determine the best course and drive the vehicle.
Automated vehicle sensors include:
Pilot programs in trucking, taxis, transit and shuttle technology are underway today. Intel outlines the speeds of some of the technologies enabling autonomous vehicles.
Autonomous Vehicles do not have to be connected to operate in Level 3 Autonomy. To realize the benefits of Intelligent Transportation Systems, Autonomous Vehicles must be Connected to enable vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) communications at Level 4 and 5.
DSRC network technology has been the source of much of the connectivity utilized for pilot programs but there is a growing movement to use C-V2X technology which will be based on 4G and 5G network capabilities. Intel predicts that a Connected Autonomous Vehicle will generate 4Tb’s of data per day during the usual daily use of 1.5 hrs.
