The idea of AV was presented for the first time in 1939 by Norman Geddes. And despite it has been only developed by universities and motor companies, was never seen as the “future of transportation” for more than 60 years. What has changed in this century then?
(1) Data storage capacity: in 1956, IBM was launching the first hard drive that stored 5 MB, at a value of 10,000 $/MB35. A quick search at the internet shows us that today it is possible to rent a space on the cloud by 0.007 $/GB/month36.
(2) Network: in 1969 was sent the first message by ARPANET, between the UCLA host (California University, Los Angeles) and SRI host (Stanford Research Institute). In 1981, the number of computers connected to the “internet” was 213. Last year, more than 1,000 million hosts accessed internet by DNS37.
(3) Information processing (CPU): computer costs has been decreasing while its performance increases. In 1961, the IBM unit 1620 was the most evolved one and the cost by GFLOP (operations per second) was around 1.1×10^12 $/GFLOPS; in 2015, the Intel Celeron G1830 costed just about 0.08 $/GFLOPS38.
(4) Bandwidth: the price of bandwidth has been decreasing over the years. In 1998, the price at the USA was around 1,200 $/Mbps; in 2015, price was around 0.63 $/Mbps, that results on an average of 35% price decrease each year39.
We consider that exponential evolution of technology was the biggest impulse for the introduction of AV in our vocabulary. But along this, the funding for AV development by the government, the introduction of new technological companies on the automotive market or events, like DARPA Challenge, that promote visibility to the subject, were also important for the opening of the Pandora box. Do you remember anymore reasons?
