A few days ago, Baidu released a traffic congestion report in major cities in China.
Beijing has won the top two consecutive promotions, worthy of being a big guy who can talk about "long-distance love" locally;
Although the congestion index of the commuting peak is "lost" to Beijing, it is still the slowest in terms of the actual speed of the commuting peak;
The little-known Great Wall rose to third, and key cities such as Shanghai, Guangzhou, and Wuhan also made the list.
Although the infrastructure has been continuously improved in recent years, the problem of traffic jams is still severe, which is strongly related to the increasing urban population, of course, some of which is also caused by driving habits.
For example, the "turtle speed" party, which is often criticized by everyone, as long as there is a slow car on a road, the entire speed is affected.
How to solve the congestion problem? Just recently Tesla CEO Musk Musk mentioned his "transportation concept" in the show, and Robin Li also published the latest Baidu traffic lecture audio course, and they all proposed their own solutions.
Whose approach can truly alleviate the traffic problem? Let the kung fu car take everyone to see it together.
Musk's tunnel dream, the first setback before the success?
In Musk's "traffic concept", he mentioned that to build a multi-layer tunnel under the ground of the city, vehicles can directly enter the tunnel through the roadside parking parking lift, and then travel to the destination at an ultra-high speed through the conveyor, so that the efficiency of everyone's commuting is greatly improved.
This idea comes from the real experience of the old horse, who complained on Twitter when he collapsed in a traffic jam together, "The traffic jam is driving me crazy!" I'm going to build a tunnel excavator and start digging tunnels." Two hours later Musk completed the official project of the tunnel plan, and many people suspected that he had just finished blocking the traffic, and when he got home, he took out his computer and released a grand plan called "The Boring Company".
In the plan, Musk mentioned that its underground tunnel network has a full 30 floors, and the vehicle is reduced to an electric platform similar to a skateboard, which has automatic driving capabilities and can reach speeds of 200km/h+. The tunnel is one-way, basically only a little wider than a car, which can minimize other emergencies. And that said, Tesla really set up a project team to dig tunnels.
However, the ideal is very full, and the reality is very bone. In June last year, Musk's first underground traffic tunnel was officially opened to traffic, but it is a version of the extreme simplicity, only an isolated tunnel was repaired, the electric flatbed car did not have, the intelligent lift platform did not, the vehicle generally could only run about 60km/h, netizens complained that it was a low-quality underground passage, and the tunnel was also simple. Musk also explained afterwards, he mentioned that the current V2X technology is not mature enough, the information linkage between vehicles can not be solved, so it is temporarily impossible to use autonomous flatbeds in the tunnel.
At the CES Consumer Show, which just held in January, many visitors chose to walk into Musk's underground tunnel to avoid traffic jams. The result was miserable, and the underground tunnel, which was said to "completely solve the problem of traffic jams", was actually congested. And because it is too narrow, the congestion cannot be cleared from the middle, which is not good.
All in all, Lao Ma's magnificent tunnel plan is not even a prototype for the time being, and it can be said that it was frustrated before the master was successful.
Robin Li's trick to cure blockages, can big data make a contribution?
In the "Baidu Traffic 7 Lecture" audio course just released by Robin Li, he mentioned his ideas for solving congestion, and he felt that the intervention of intelligent technology can greatly alleviate traffic problems.
He mentioned that intelligent transportation should not only make cars become intelligent, but also have "smart roads", and doing a good job of "vehicle-road coordination" may be the ultimate way out. In fact, Baidu's intelligent transportation solutions have been implemented in many cities, including intelligent traffic management, intelligent parking, intelligent high-speed, etc., which can alleviate congestion to a certain extent.
Robin Li mentioned a real case, in Qiyi Road, Baoding, Hebei Province, citizens usually block five or six traffic lights during peak travel periods. After the local traffic police adopt Baidu's AI intelligent control system, the traffic lights can intelligently adjust the control time of the traffic lights according to the real-time traffic situation, so that the traffic efficiency is improved by a full 20%. For example, some vehicles have achieved 12 consecutive intersections to encounter green lights, which was unimaginable before.
This is a very typical big data congestion, with the continuous improvement of computing models, and the use of the same technology continues to increase, I believe that the congestion problem will be greatly improved.
Of course, Robin Li also mentioned his own Baidu Apollo autonomous driving solution, he said that his technology has been quite mature, his "radish run" service platform has opened manned test operation services in seven key cities, and has begun a new round of negotiations with a number of key car companies.
If both the car and the road get smarter, maybe solving congestion is a matter of course. However, the keywords mentioned by Robin Li are mostly the future, and the promotion may also have a long time.
Can the all-round efforts of people, roads and planning really cure the blockage?
Regarding the problem of traffic congestion, the majority of people who commute to work and drive every day may be more convincing, and many netizens have proposed their own solutions, which is very interesting.
For example, many netizens complained that there are thousands of traffic jams, and turtle speed driving accounts for more than half. Many people drive slowly in one car, pressing a bunch of cars behind them. Some people especially like to wait for the traffic lights to play mobile phones, and then the green lights start to delay for a few seconds, and the cars behind them are more and more congested. Netizens proposed that urban roads should also be divided into fast, medium and slow three lanes, driving in each lane is limited speed, driving speed can not be less than 10% of the prescribed speed, otherwise the same deduction points.
Then through big data records, such as congestion on a certain road at high speed, if it is because of the congestion caused by some vehicles driving at a high speed, starting slowly, forcibly adding congestion, etc., then the points should be deducted, the fine should be fined, and those who really can't do it rush back to the driving school to continue their studies until the driving level reaches the requirements of the road.
Some netizens also mentioned the problem of urban construction, believing that the current congestion is because the city tends to make some companies very concentrated, so that the area where everyone works is concentrated. A lot of people live in the suburbs and have to squeeze into the city because the job opportunities are there, and some people live in the city but work in the suburbs. If the office area is dispersed, the number of people working across the area will be greatly reduced, and the commuting pressure will also come down.
If these functions cannot be evacuated, it can also be considered that private cars are restricted in the urban center and only public transportation is allowed. Arrange suitable parking places for private and official cars in the outer ring of the central area to be centrally managed, which can also greatly reduce the problem of commuting.
In any case, everyone's original intention is to hope that the city will become better and better, so that the life of ordinary people will become less difficult.
Kung Fu shoots
Musk's vision is perfect, but it is really too difficult to implement, and it may not be possible until the technology has a big breakthrough. Robin Li's big data has achieved certain results, but there is still a long way to go from the real application.
The city is getting bigger and bigger, and perhaps the most realistic thing at the moment is that everyone should improve their traffic literacy and strictly abide by the traffic rules, or at least not take the initiative to "add congestion" to the city.
