——the importance of safety belt

2. History Invention of seatbelt
In 1885, Edward J. Claghorn applied for the first US seatbelt patent in New York.
The patent indicated, "designed to be applied to the person, and provided with hooks and other attachments for securing the person to a fixed object.”

3. history A huge step forward
In 1958, Nils Bohlin, an engineer from Volvo, patented a three-point belt system. It crossed the lap from side to side, but the chest, diagonally.
In 1959, Volvo introduced Bohlin’s three-point belt on the model called “Amazon”, Volvo Amazon became the first car ever to come with three-point belt as standard.

4. history
In 1961, two states, New York and Wisconsin pass laws mandating front seat riders have access to seat belts. As the 60s pushed forward, other states followed.
By 1970, seat belts would become standard in U.S. cars, but getting them in the cars, and making people wear them would need more efforts.

5. statistics
In Europe, the safety belt is estimated to reduce road fatalities by 40 percent every year. Within the EU in 2005, an estimated 11,700 drivers survived road accidents because they were wearing safety belts. The figure for Germany alone was 2,000. Had these drivers not been using the belt, the number of fatalities in Germany that year would have doubled.
Corresponding estimates for the USA in 2004 show that safety belt use saved 15,200 lives and resulted in society saving 50 billion dollars in costs.

6. advocation
More convenient belts and the introduction of seat belt reminders have proven to be effective methods. Having said that, legislation, fines, campaigns and inspections are the main factors that increase safety belt usage.
While in some developing countries, especially those with rapidly growing car ownership, education is the most effective action a country can take. Telling kids about the importance of putting on seatbelt will not only affect them but also their parents.

Exploring the future self-driving approach combined with AI, Cloud Computing technologies and new energy
By Wuxi No.1 High School

10. How could AI help the car Self-driving
The use of modern AI (Artificial Intelligence) technology have appeared in automotive industry since The famous competition The Grand Challenge held by the US government propel the autonomous vehicle. AI technology was largely used in this competition and brought the top teams a good result. (Stanford team, CMU
team and MIT team)

11. How could AI help the car Self-driving
In recent years, the AI-powered autonomous driving is not a rare term but more like a competition that most the automotive companies (BMW, Ford, General Motor) are working on.
The most success one Waymo powered by Google have achieved miles with disengagement per 5000 miles. And the second one BMW achieved 638 miles per disengagement. These examples prove that the self- driving is possible and meaningful to the current situation.

12. How to implement self-driving
A self-driving car should consist of sensors and computing units. These components are replacements for the human eyes and brains and they are more precise and formalized than the human organs.
The computing units are coded with pattern recognition, PID system, emergency response to secure the life of car owner and
pedestrians.

13. Pattern recognition
To find and utilize a perfect pattern recognition algorithm, we first need to collect every situation that may appear on the roads.
Computer simulation with machine learning to each type of car is required. The developers can should create a database with all types of cars available on the roads and start machine learning algorithms. Scanning 3D models then generated from the database and write to every single self-driving car. With the images provided by camera sensor, the self-driving car will find the best- match for the car detected.

14. Pattern recognition
We cannot only make pattern recognition algorithm for the cars. We need to handle more situations. Different weather situations like raining, snowing, foggy or even hailing should be considered and adaption to the system should be made.
In fact, if the vehicles only rely on the physical sensors installed around the car, it is very difficult for the sensors to work properly under different weather conditions. Water vapor or snow will drastically reduce the accuracy of the sensors and lead to traffic accident.
Setting slower speed or using more advanced sensors will increase the prize of the car, reduce the sales of cars. A better solution is to connect the vehicle to the cloud

15. Cloud computing for vehicles
Cloud computing is then introduced to break the limit of sensors and computing units. If we can have driving app installed on the car owners’ smartphones and request their permission to use the location data, computing of cars and traffic can be done on the cloud and immediately send to every vehicle driving on the road. This approach does not replace the sensors, but make the vehicle smarter to drive around each other.

16. More than self-driving
To now we only designed an early mode for self-driving vehicles. Along with the increment of the public acceptance on self-driving vehicles, we should be able to create a network of transportation on each vehicle and handle all the vehicle information on such network. Every vehicle on the roads are connected with each other and communicated. Information like destination and car speed are shared among the vehicle and the central server will allocate the routine and even the traffic light for more efficient transportation.

17. New-energy Cars-Electric cars
Introduced more than 100 years ago, electric cars are continuously gaining popularity in recent years. The expected annual sale by 2020 globally can reach 6.6 million per year.
The categories of new-energy cars can be classified into mainly three types, which are hybrid, plug-in hybrid, and all-electric.

18. Advantages of electric cars
Less air and noise pollution
Better performance under poor road conditions
Reduction on dependence on foreign oil
Reduced Maintenance
Lower cost: consumers can receive subsidy from the government currently

19. Disadvantages of electric cars
Few currently available recharge stations
Relatively long recharge time
Short driving range and speed
Silence: might cause danger to the pedestrians
Mostly small sizes

20. Advancement made in recent years for new-energy cars
Improvement of durability of the battery
Reduction in electric vehicle battery cost
More choices for the consumers, varying form midsized cars to luxury cars

21. The future
The future of the vehicles is bright. With clean energy and effective transportation structure based on modern technology, we can reconstruct the current situation and solve traffic problems.
As people become more and more concerned with the environment and the technology for new-energy cars is continuously improving, the advantages of new-energy vehicles overweigh the disadvantages associated with them. New-energy vehicles will gain additional popularity in the future.

22. Efficiency of electric cars
As shown in the graph, electric cars have more advantages in energy efficiency over the cars powered by petrol. Therefore, electric cars will be a trend in the future for sustainable development.
