What is intelligent transportation? What is intelligent transportation? What is the role of intelligent transportation system?

The Intelligent TransportaTIon System (ITS) is the development direction of the future transportation system. It is the effective integration of advanced information technology, data communication transmission technology, electronic sensing technology, control technology and computer technology into the entire ground. The traffic management system is a real-time, accurate and efficient integrated transportation management system that works in a wide range and in all directions.

The intelligent transportation system has the following two characteristics: one is to focus on the wide application and service of traffic information, and the other is to improve the operational efficiency of existing transportation facilities.

Compared with the general technical system, the integrity requirements in the construction of intelligent transportation systems are more stringent. This holistic manifestation is reflected in:

(1) Cross-industry characteristics. The construction of intelligent transportation systems involves many industry sectors and is a complex mega-system project in which the society is widely involved, resulting in complex inter-industry coordination problems.

(2) Features of the technical field. The intelligent transportation system integrates the achievements of many scientific fields such as traffic engineering, information engineering, control engineering, communication technology, and computer technology, and requires technical personnel from many fields to work together.

(3) The government, enterprises, scientific research units and institutions of higher learning participate together. Appropriate role positioning and task sharing are important prerequisites for the effective implementation of the system.

(4) The intelligent transportation system will be mainly supported by new-generation information technologies such as mobile communication, broadband network, RFID, sensors, cloud computing, etc., which is more in line with human application requirements, and the degree of trust is improved and becomes “ubiquitous”.

1. Advanced Traffic Information System (ATIS)

ATIS is based on a well-established information network. Traffic participants provide real-time traffic information to the traffic information center through sensors and transmission equipment equipped on the road, on the bus, on the transfer station, on the parking lot, and in the weather center; ATIS obtains this information and processes it in real time. Provide road traffic information, public transportation information, transfer information, traffic weather information, parking lot information, and other information related to travel to traffic participants; travelers determine their own travel modes and route selection based on this information. Further, when the car is equipped with an automatic positioning and navigation system, the system can help the driver to automatically select the driving route.

2. Advanced Traffic Management System (ATMS)

ATMS has a part of the information collection, processing and transmission system shared with ATIS, but ATMS is mainly used by traffic managers to detect and control road traffic and provide communication links between roads, vehicles and drivers. It will monitor the traffic conditions, traffic accidents, meteorological conditions and traffic environment in the road system in real time, relying on advanced vehicle detection technology and computer information processing technology to obtain information about traffic conditions and traffic based on the collected information. Control, such as signal lights, release guidance, road control, accident handling and rescue.

3. Advanced Public Transportation System (APTS)

The main purpose of APTS is to promote the development of the public transportation industry by using various intelligent technologies, so that the public transportation system can achieve the goal of safety, convenience, economy and large volume. For example, through personal computers, closed-circuit television, etc., to provide advice to the public on travel modes and events, routes and train selections, and provide real-time operational information of vehicles to the waiting passengers through the display at the bus station. In the bus management center, it is possible to reasonably arrange the start and stop plans according to the real-time status of the vehicle to improve work efficiency and service quality.

Education Tablet

As a mobile multi-purpose platform, tablet computers also provide many possibilities for mobile teaching. The touch-based learning & entertainment teaching platform allows children to efficiently improve their academic performance in a relaxed and pleasant atmosphere. Such tablet computers generally integrate two learning sections of various courses and systematic learning functions. Generally, it includes multi-disciplinary high-quality teaching resources. The education tablet has the following main functions: it has the functions of touch screen input, text editing, picture editing, data storage, data management, wired and wireless Internet access that ordinary tablet computers have; Management functions, search methods support manual search, query by keyword, query by time; text and pictures can be scanned and converted into documents to save.
