smart infrastructure for autonomous vehicles
DESCRIPTION
These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze how autonomous vehicles are becoming economic feasible. They are becoming economically feasible because the cost of lasers, ICs, MEMS, and other electronic components are falling at 25 to 40% per year. If the cost of autonomous vehicles fall 25% a year, the cost of the electronics associated with autonomous vehicles will fall 90% in 10 years. Dedicating roads to autonomous vehicles is necessary to achieve the most benefits from autonomous vehicles. While using autonomous vehicles in combination with conventional vehicles can free drivers for other activities, dedicating roads to autonomous vehicles can dramatically reduce congestion, increase speeds, and thus increase the number of cars per area of the road. They can also reduce accidents, insurance, and the number of traffic police. These slide discuss the use of wireless technologies for the control and coordination of autonomous vehicles. Improvements in bandwidth, speed, and latency (delays) along with improvements in computer processing are occurring and these improvements are making dedicated roads for autonomous vehicles economically feasible.TRANSCRIPT

Introduction
Autonomous technology has already achieved a
high degree of development.
Technology is emerging gradually but continually,
with new opportunities
Technical and Economic feasibilities AVs and
Dedicated Roads will be discussed.
Implementation by Stages (AVs, Roads)
Even though so much research and
improvements in AVs have been
put in place, we need to focus on
the infrastructure for AVs as well
Integrated Features & Technologies(MEMS, Lasers, Radars, Lidars, Sensors, GPS, Ultrasound, Cameras, Communication & Networking)
Major Features Functions & Technologies Associated Benefits
Autonomous Emergency Braking (AEB)
Adaptive Cruise Control (ACC)
Lane Keeping Assist
Automatic parking
Networking (V2V, V2I towards V2X)
Detects Obstacles (Radar, Lidar)
Maintains a safe distance from car in front
(Radar, Laser, Camera Sensor)
To detect lane markings, to warn driver, to
auto-correct positioning (Laser, Video
Sensor, IR sensors)
Automatic parking for parallel/ right-angle
parking spaces (Sensors, Memory Chips)
Vehicle-to-Vehicle (V2V)
Vehicle-to-Infrastructure (V2I)
AEB reduces accident by 27%
Change/ maintain the speeds
automatically, reduce crashes
Allows driver to be ‘hands-free’
Driver can get out of the car and
command the car to park itself, smart
phone command can be used
Share info, Prevent collision,
consistent speed in road-train traffic

Pros and Cons of Technologies in Development
Path to Technology Convergence (Hurdles to Overcome)
http://www.kpmg.com/US/en/IssuesAndInsights/ArticlesPublications/Documents/self-driving-cars-next-revolution.pdf
Improved Positioning Technology:
High-Resolution Mapping:
Reliable and Intuitive Human Machine Interface (HMI):
Standardization
Path to Technology Convergence (AVs + Roads)
•Can we achieve a safe, self-driving vehicle on the dedicated roads/ infrastructure?
• Yes. Google and other automakers had done it before… but on the Vehicle Technology only..
• What’s missing?
• The convergence of technologies (Combined Infrastructure)
http://www.kpmg.com/US/en/IssuesAndInsights/ArticlesPublications/Documents/self-driving-cars-next-revolution.pdf
Autonomous Vehicles are conceived to adapt to current road
but we can also imagine specific highways entirely dedicated to these vehicles
What are the features needed?
We need then:
1. Adapted to higher speed limit (less curves..)
2. Less need of parking slots (cars can just drop off users)
3. Reduction of physical road signage, replace it by
wireless communication
4. Centralized motion planning that communicate
with all the sensors and all the vehicles
5. Decentralized solution
Cooperation vs. Autonomy
source: UC Berkeley
Autonomy Solution
● Every single car does its own trajectory calculation in
function of the cars surrounding it.
● Roads transmit them the entire informations regarding
the road map.
Autonomy Solution
The roads only need communication to system: Car/Road
● Continuous communication
● Cover all the road
● Fast enough (<1s)
Communication system Car/Road
Wireless communication
● long-range wifi: not enough scope (32 m)
● Cellular data services: good latency (5ms)
● Mobile Satellite Communication: bad latency (650ms)
Expected rate of improvement
10% improvement each year
Sensor Limitation
To improve safety we need to accumulate the number of
sensors wich increase cost and vulnerabilities because of the
complexity
Cooperation systems can be a solution
Autonomous solution: easier to propose but...
...Cooperation system advantages are interesting:
● Lower prices (less sensors)
● Current and planned actions (better flows)
● Identification of hazards
● Earlier and safer responses possible
Cooperation Solution

Detecting Entry Car ?
● Car must be detected and tested
○ to ensure it is an AV
○ car must submit a travel plan
● Barriers at the entry with wireless detection (like in Highways)
○ The technology already exists
Centralized Roads
We need:
● Communication system Car/Road
● Processing power
● Disturbance detection system
What is the Algorithm?
On-Road Motion Planning for Autonomous Vehicles
research by Gu and Dolan from Carnegie Mellon University
● optimal trajectory use use Dijkjtra and A* algo
● lane-based trajectory generation by rolling out trajectories based on
lateral shifts from the lane centerline
Processing Power
● Dijkstra complexity
● 100 km highway
● 200 km/h medium speed
2014 prices of HP cloud compute services:
0,012$/GHz/min
Google car current
expected price:
320 000 $
● 5 car/sec
● Moore’s law
● 2014 prices of HP cloud compute services
Disturbance detection system
● Global navigation satellite systems: 10 m precision
● Regional systems: old tech and bad precision
● Diferential GPS, Satellite and base system: 10 cm
Expected rate of improvement
What could Vinci do to construct autonomous roads?
The goal of Vinci wouldn’t be to manufacture autonomous vehicles, but to coordinate all vehicles on the roads.
What could Vinci do to construct autonomous roads?
It is very difficult and expensive to construct new roads. It is much easier to adapt
current roads to autonomous vehicle:
The first step is to connect every car to the network
➔ Cellular data services on roads, free connection of every car to the
network
➔ Differential GPS for every car
What could Vinci do to construct autonomous roads?
The second step is to analyse all these datas
➔ Data center : collect data from every car and centralize it
➔ Big data algorithms to take the best decision in real time for every car
What could Vinci do to construct autonomous roads?
The third step is to send all the individual answers to every car
➔ Cellular data services on roads, free connection of every car to the
network
➔ The car doesn’t only “see” what is around, but sees what is 100km
forehead too.
What could Vinci do to construct autonomous roads?
Other costs for Vinci :
➔ Need higher surfacing quality (for higher speed)
➔ Need less curves and less differences in high
➔ Need infrastructure to secure the network (pirating risk must
be 0)
What could Vinci do to construct autonomous roads?
Earnings for Vinci
➔ More cars/second on roads
➔ Less accidents
➔ Dominant design
