Abstract
The automotive industry is transitioning towards intelligent, connected, and autonomous vehicles to avoid traffic congestion, conflicts, and collisions with increased driver safety. Connected and autonomous vehicles (CAV) must be aware of their surroundings and act as per their environment. Communication infrastructure can be vital in transmitting necessary information to peers and receiving critical information for timely decisions. This article provides a comprehensive review of the topic, covering the aspects of enabling wireless technologies and sensor fusion. The article reviews data acquisition using various sensing devices such as RADAR (Radio Detection and Ranging), LiDAR (Light Detection and Ranging), cameras, and multi-modal sensor fusion of the acquired data after signal processing. Thereafter, it reviews the communication and networking infrastructure for intra- and inter-vehicle communication and related technologies. For each of these themes, research challenges and future directions have been identified.
Highlights
The field of vehicular communication and intelligent transportation systems (ITS) has been progressing fast since the last decade
COMMUNICATION AND NETWORKING IN Connected and autonomous vehicles (CAV) At this point, we have developed a basic understanding of CAV and how these vehicles work
Results from this paper show that guardrails with low RADAR cross-section (RCS) improve the visibility of adjacent stationary targets, and have the potential to reduce accidents and possibly save lives
Summary
The field of vehicular communication and intelligent transportation systems (ITS) has been progressing fast since the last decade. General Motor organized an exhibition in 1939 named as New York world’s fair to show the world its vision of how the world in the future will look like with CAVs on the road They showed the concept of an automated intelligent highway system with connected vehicles. The focus of this challenge was for military applications of autonomous vehicles It created huge interest in big companies like Tesla, Google, General Motors, Ford and others who made huge investments in developing CAVs. In 2014, Tesla showed the world its first ever autopilot car. A lot of progress has been made since over traditional vehicles on the road and companies like Tesla and Google are working really hard to bring CAV on the public road with advanced technological features in the near future. CAVs can communicate with parking lots to find empty slot and can self-park to save precious human time
