At the end of the 20th century, as the number of cars increased, problems such as traffic congestion and frequent accidents became prominent. Therefore, intelligent transportation systems that use a variety of new technologies such as information technology, electronic sensing technology, satellite navigation and positioning technology have emerged. Its essence is to consider people, vehicles and roads comprehensively. People refer to all people related to the transportation system, including traffic managers, operators and participants; vehicles refer to the vehicles of various modes of transportation; Road refers to roads and routes.
Smart transportation is based on intelligent transportation, integrating high-tech technologies such as the Internet of Things, cloud computing, big data, and mobile Internet to install a "brain" for transportation to make transportation more advanced, smart, and intelligent .
Nowadays, smart transportation has penetrated into our lives unconsciously. Devices such as shared bicycles, online car-hailing, time-sharing rentals, charging piles, etc. are the use of resource sharing systems to play a role in the field of transportation resource allocation. Expand the scope of monitoring in high-risk areas such as bridges, tunnels, dense fog, wind and snow, etc., and set up electronic police, high-definition checkpoints, license plate captures, traffic lights, etc. at road intersections to guide passing vehicles, and continue to move towards smarter regional monitoring. . In addition, there are electronic bus stop signs, automatic ticket collection systems and facial recognition systems and other technologies.
Taking driverless cars in future smart transportation as an example, if an urban road has four lanes in both directions and two parking lanes, the road left for pedestrians will become very narrow. To form a smart transportation system, it is necessary to realize smart travel well. With the improvement of autonomous driving technology in the future, the error tolerance of traditional road width and the isolation zone in the middle of the road will disappear from the stage of history. After the driverless car delivers you to your destination, it can find a parking lot on its own. In this way, a large amount of existing motor vehicle road space and roadside parking spaces will be released. The rebalanced right of way will revitalize the original narrow and noisy pedestrian space, and create a slow-moving space composed of pedestrian trails and bicycle lanes. It will become a social place for people to communicate freely.

In recent years, autonomous ships have gradually received attention. The key capability of unmanned ships is to be able to sense and communicate what is happening around them, so as to perform complex operations, avoid collisions along the way, and successfully navigate to their destination. A machine learning engine built in the cloud can provide support for the ship's image recognition system, while images from high-definition visible and infrared cameras are combined with lidar and radar measurements to provide detailed images of the ship's surroundings. These new technologies can reduce cargo losses caused by human accidents. In addition, since no crew is required, the space and facilities originally provided for the crew can be saved, allowing the ship to have greater cargo carrying capacity and improve transportation efficiency.

Smart transportation is increasingly entering people's lives. Buying air tickets and train tickets, checking flights, train numbers, subways, buses, and road conditions are all inseparable from smart technology. Transportation services. As intelligent connectivity has become a hot word in recent years, future travel methods will make smart life within reach and become an important starting point for realizing a powerful transportation country in the future.
