Recent times have witnessed tremendous development in the genre of autonomous vehicles. The rampant evolution in Information and Communication technologies, Internet of Things, Artificial Intelligence and Block Chain has changed the human lifestyle. The profound impact of these technologies has raised the market of building safe and reliable vehicles. The proposed framework taps the Block chain technology, a decentralized ledger scheme with high degree of reliability in developing a spatio-temporal collision avoidance system. The heterogeneous sensors deployed at every vehicle monitors the motion of vehicle and forewarns all the nodes connected to the system about the chances of collisions based on individual vehicle’s motion and proximity. This framework can be implemented on the existing network infrastructure. The design challenges discussed in the latter part offers a wide scope for future researchers in building autonomous vehicles with ensured safety.
