In the strategic keyword of 2017, smart traffic ranks second, second only to practicing internal strength, which is enough to see its importance to Dripping. To this end, Didi Chuxing newly established the Smart Traffic FT Team (Feature Team), which is entirely responsible for Zhang Wenxuan.
What should you do when you are traveling smartly? How to achieve technically? Why do we need smart traffic? In this exclusive interview, Zhang Wenzhao shared his thoughts and opinions.
What is smart transportation?
Zhang Wenzhao said that the smart transportation system will be joined by local governments to create a system for smart travel, smart supervision, smart operation, and smart decision-making based on Internet + traffic big data. The system has both unique and core big data. The high-tech foundation can combine well with the local traffic big data, road network characteristics, and public travel characteristics.
The city’s public transportation buses, subways, taxis, bicycles, road facilities, etc., will be connected with the travel and travel data of the city. This will form a leading global government-enterprise cooperation integrated traffic big data platform. The platform has two major advantages: the most real, accurate, real-time, and perfect big data. This is the basis of “Internet + Transportation†and the leading data algorithms, technical strengths, and rich experience of DDT in mobile travel.
On this big data platform, Didi will work with local governments to build a smart transportation system that will make the entire city more efficient in transportation, provide better public travel experience, and empower urban traffic management.
Didi's smart transportation strategy is gradually being launched in multiple cities. For example, the traffic data collected by the Traffic Management Bureau and Drip Trips will be integrated into the intelligent traffic guidance screen of urban roads. The guidance screen can not only display the traffic in front of the road in real time. The situation can also predict the time required to go forward by using the ETA (estimated arrival time) technology, which will make the urban traffic guidance system more intelligent.
In the “Internet + Signal Lights†aspect, Drips more accurately assess regional traffic flow by integrating reliable Internet track data and coil and bayonet data, and optimize reasonable traffic light timing and phase difference, and optimize maximum regional traffic when saturated. Quantity, intelligent control of signal lights, greatly improving the traffic environment.
The nation’s first network of smart lanes at Shenzhen Airport is an important attempt to make use of Internet big data technology at important transportation ports to enable passengers to get off the ground quickly, improve road utilization, and improve passenger travel efficiency.
In addition, DDT has begun to use large-scale travel data and traffic data combined, through the analysis of data published urban traffic metrics report, to achieve a clear judgment of the overall traffic situation, help decision makers to develop relevant traffic strategies.
Compared to previous attempts in the transportation sector, Didi's smart traffic marks the arrival of China's urban evolution 3.0. Zhang Wenxuan believes that urban evolution 1.0 is an initial informatization of urban transportation and other fields, for example, data collection such as cameras and signal lights; urban evolution 2.0 is to open traffic data in cities, for example, cameras, signal lights, etc. After the data was opened up, it was comprehensively used; and the smart traffic that Djichuxing traveled together with local governments was Urban Evolution 3.0, which opened up big data between the local government and the mobile travel platform and used the world’s leading high-tech algorithms. , Convergence of big data in both traffic areas will translate into Internet applications that can directly facilitate users' travel and create smart transportation to travel.
How to make smart traffic?
Zhang Wenxuan introduced that the smart transport system will be divided into three levels: on the user, on the enterprise, and on the government level. Once the smart transportation system is set up, it will be able to play a huge role and bring different benefits to all the travelers in the city, the travel related companies, and the city's manager-government.
For travelers in cities, the smart transportation system will build a "one-stop travel platform." Relying on this big data platform, under the guidance of local governments, Didi Travel will use the world's top-level traffic data big data algorithm, and eventually make the city travel by using artificial intelligence technology based on big data such as intelligent scheduling, route planning, and transaction engines. To build a world-leading "one-stop travel platform."
The "one-stop travel platform" will provide users with a one-stop travel solution. In the future, the user can see all travel combination solutions from point A to point B in one page of the Drip Trip App. Among them, there will be the most time-saving, most cost-saving and other recommended programs. For example, the most cost-effective solution is to ride a shared bicycle from point A, then take a bus, then transfer to the subway, and finally use Drittle Express to reach point B.
In the future, based on the deep mining of big data, the “one-stop travel†of smart transportation can also be based on the tendency of different users, for example, preferring express trains, private cars or buses to travel, giving each user a more personalized travel plan recommendation. , make everyone's travel faster and better.
On the corporate level, it is worth noting that, in this drastic organizational restructuring, the bus division was officially renamed the Public Transport Division, and it was integrated into the smart traffic, which means that the smart traffic will be the future city. The bus companies in China have greatly helped.
In the future, Smart Transportation will cooperate with bus companies around the world to provide users with real-time query services for public transport information, carry out data center and intelligent dispatch management platform business, and customize urban bus services, creating a new generation of smart public transport for the public. A new generation of smart buses will help bus operations management to achieve intelligence, improve the efficiency of bus operation and management, and use technology to serve passengers to facilitate travel.
First of all, it will solve the problem of “waiting for a train†and increase the certainty of bus travel. Second, future smart transportation will also provide data analysis support and recommendations for optimization of public transportation network based on user query data and travel requirements. The public transport network planning data can be referenced, and citizens' needs can be fully expressed and adopted. Third, smart transportation will also use technology upgrades to increase the efficiency of bus dispatching and make bus operations more dynamic. In the future, Didi will output dynamic carpooling, regional minibus and other product technologies, and link the local bus companies online and offline to provide citizens with a smarter last-mile solution.
At the government level, smart transportation will provide the government with traffic operation supervision and decision support. Through the optimization of urban traffic infrastructure such as traffic guidance screens, intelligent traffic lights, tidal traffic lanes, HOV lanes, and congestion detection, the development of the smart transportation industry ecosystem will be jointly promoted.
Through cooperation with local governments, DDT can use intelligent scheduling to help manage urban traffic and improve the city's traffic congestion. From the spatial perspective, Djihui can plan different roads for the citizens and balance the traffic volume of each road network. Drops will also be “cutting peaks and filling valleys†from the time dimension through operational means.
In a deeper sense, ITS can provide the decision-making basis for Shenzhen's urban road network optimization. For example, in the four lanes, whether there should be one or two left turns, accurate suggestions can be given. Didi will also make plans for the city's new road network, for example, where it should build roads, or whether it should build a bridge.
Why smart traffic can not be drip?
According to Zhang Wenyu, the FT team has drawn talents from various technical lines, business units, and functional departments to form a professional and flexible project team, focusing on smart transportation projects. In the future, Didi will become the world's largest provider of smart transportation integrated services.
"Dripping platform, peak demand receives more than 20,000 passengers per minute, 70TB+ daily positioning trajectory data, equivalent to 70,000 movies; processing data up to 2000TB per day; daily route planning requests exceed 9 billion, about The equivalent of 6 million times/minute... In the transportation field, the scale of such big data is currently only available.†Zhang Wenxuan said that a large amount of travel data is the core asset of Didi, which is also the most obvious in the field of smart transportation. The important reason for the right to speak.
In addition to the advantages of big data, Dickey has accumulated a great deal of experience in analyzing and processing data. Zhang Wenzhao said that China's traffic travel is a world-class challenge. Whether it is the instantaneous processing of massive data, or the complexity of urban road networks, and the imbalance between supply and demand, the complexity of China's transportation system cannot be compared by any country. No matter big data technology or artificial intelligence technology includes the construction of the entire security system, China can walk in the forefront of the world.
Zhang Wenxuan said that one thing that cannot be overlooked is that DDT travel has a strong C-side operational capability. This means that all the Internet products and applications that are produced together with the local governments for smart transportation will have C-end users able to use them directly, truly realize Internet big data and high technology, and be able to serve the people and the general public in the transportation field. .
Braille signage typically consists of raised characters that can be felt with the fingertips. These characters are embossed onto the sign surface, allowing individuals to read the information using their sense of touch. Braille signage is usually accompanied by visual text and graphics to accommodate individuals with varying degrees of visual impairment.
Braille signage is essential for promoting accessibility and inclusivity. It allows individuals with visual impairments to navigate public spaces safely and independently by providing information about room numbers, restroom locations, elevator access, emergency exits, and other important details. Additionally, Braille signage can also include tactile symbols to convey information about specific amenities, such as elevators, staircases, restrooms, or parking spaces.
