4. Urban public transportation informatization At present, domesticThe information application of the public transportation system is still relatively backward. The intelligent public transportation dispatching system is basically in a blank stage in China, which is also an area that the solution provider can focus on developing. In terms of geographical distribution, major cities in China, especially the southern coastal areas, attach great importance to the development of intelligent transportation.

5. The development of urban rail has great potential. It is an effective measure to solve China's urban traffic problems. At the same time, it will also become the mainstream direction of public transportation construction in many big cities in China.

6. ITS can effectively use existing transportation facilities, reduce traffic load and environmental pollution, ensure traffic safety, and improve transportation efficiency. Real-time dynamic traffic management and traffic monitoring make intelligent traffic management system the best urban traffic solution. Intelligent transportation is a field with strong national relevance.

What is "smart transportation"? What does intelligent transportation refer to? What does it contain?

1. Intelligent transportation refers to a transportation-oriented service system based on modern electronic information technology.

2. Smart transportation is a new transportation development model based on the Internet, the Internet of Things and other network combinations, and takes smart road network, smart equipment, smart travel and smart management as important contents. It has the basic characteristics of information connectivity, real-time monitoring, management coordination and character integration.

3. The concept of intelligent transportation Intelligent transportation refers to a transportation-oriented service system based on modern electronic information technology.

4,Intelligent transportation is a transportation-oriented service system that makes full use of the Internet of Things, cloud computing, artificial intelligence, automatic control, mobile Internet and other modern electronic information technologies in the field of transportation.

5. Intelligent transportation refers to a transportation-oriented service system based on modern electronic information technology. Its outstanding feature is to provide diverse services for traffic participants with the collection, processing, release, exchange, analysis and utilization of information as the main line.

What does GSM mean

GSM's full name is Global System for Mobile Comm Unications, a global mobile communication system in Chinese, is a digital mobile phone network standard developed by Europe.

"gsm" is the unit of weight of international paper degree, which means Gramme/Square Meter. For example, "90gsm" means that a piece of paper weighs 90 grams per square meter. Generally, the higher the number of gsm, the thicker the paper is.

GSM refers to the global mobile communication system.The global mobile communication system is a digital mobile communication standard formulated by ETSI, the European Telecommunication Standards Organization. Its air interface adopts time-time multi-address technology. Since it was put into commercial use in the mid-1990s, it has been adopted by more than 100 countries around the world.

What aspects does intelligent transportation include

What aspects does intelligent transportation include? The intelligent transportation system mainly includes the following parts. TrafficInformation acquisition system manual input, GPS on-board navigation instrument, GPS navigation mobile phone, vehicle traffic electronic information card, CCTV camera, infrared radar detector, coil detector, optical detector, etc.

Smart transportation usually includes: smart transportation infrastructure, smart transportation travel, smart traffic dispatch and command, smart road traffic management, smart Hong Kong aviation management and smart road administration management.

The main functions of the intelligent traffic system include the following: the application subsystem includes traffic information acquisition system, traffic light control system, traffic induction system, and parking induction system. Make full use of the collected information, release the corresponding traffic congestion situation in a timely manner, guide the best route information, and provide reference for travelers.

Intelligent transportation is a transportation-oriented service system based on modern electronic information technology.It is characterized by the collection, processing, release, exchange, analysis and utilization of information as the main line, providing diverse services for traffic participants. That is, using high technology to make the traditional transportation mode more intelligent, safer, more energy-saving and more efficient.

What new technologies are included in smart transportation? Intelligent transportation refers to the use of traffic science, big data, automatic control and other theories and technologies to establish a real-time dynamic information service system, so as to obtain relevant data on transportation, intelligently design travel routes and methods, and improve the probability of traffic jams, congestion and traffic accidents.

What is the difference between communication and information system and signal and information processing?

1. The formerFocus on the interaction of communication, such as how to encode 0 and 1 (channel coding), as well as MIMO, etc., as well as communication network architecture, channel model, etc., focusing on interaction and communication, and do not care what the content of the signal is. It is only responsible for accurate delivery from 0~1, so it often involves modulation and decoding. , intertwining, error correction, etc.

2. Communication and information processing generally involve the encryption, encoding and decoding of communication. It is limited to the scope of communication, but the scope of signal and information processing is very wide. For example, the information processing of communication is also a part of signal and information processing. In addition, signal acquisition and processing in common industrial control.

3. I study communication. Signals focus on the transformation of sending and receiving signals. There are more mathematical requirements. For communication systems, the research channel efficiency is more, including signal processing and a wider range.
