As of the end of 2012, the number of motor vehicles in China was 240 million, of which 120 million were in cars. In 2012 alone, the total length of newly opened roads was 87,000 kilometers, and the total length of highways was close to the world's first. At the same time, the population with car driving licenses has reached 180 million, and is growing at a rate of more than 10 million new people every year. China is becoming a country on wheels, and ICT is spreading on every road with the rhythm of each wheel. An intelligent traffic management system is gradually formed on the road network and wheels.
Information and communication technology facilitates efficient travel
Intelligent transportation for efficient travel
The traditional urban traffic management model has been difficult to alleviate the contradiction between the rapidly growing traffic demand and insufficient traffic facilities, so the construction of an "intelligent traffic" system is imperative. At present, intelligent transportation mainly adopts technical means such as monitoring, monitoring, and optimization of traffic flow distribution to complete monitoring and information network systems in public security, urban management, and highway traffic. Based on this, a systematic and relatively unified intelligent urban traffic comprehensive management and traffic service platform can be established, which can realize various functions including traffic guidance, emergency command, intelligent travel, taxi and bus management, etc.
In the network management center of China Mobile's Guangdong company, the reporter saw that the real-time road conditions of the highways in Guangdong can be checked at any time. "Last year, the Guangdong Provincial Party Committee and Provincial Government gave us a task to monitor road conditions for free travel on festive highways. We installed cameras based on the base stations along the highway to achieve real-time continuity of highways in Guangdong Province. Road condition monitoring. "A staff member of the Guangdong company told reporters," We have effectively monitored the sudden changes in highway traffic by establishing mathematical models such as traffic, passenger flow, traffic flow, and vehicle density. "Since the Mid-Autumn Festival last year Since the implementation of the highway free policy, Guangdong Mobile has found a total of 846 road congestion or slow events through the highway network security command system, and solved 20 performance degradation problems in a timely manner.
In Wuhan, the reporter saw the arrival time of vehicles on the main bus lines of the city very clearly displayed. Citizens can download a smart bus client on their mobile phones or use the bus electronic stop sign to know the arrival time of vehicles. Liu Kai of Wuhan Bus Group Information Center told reporters that this application in cooperation with China Unicom Hubei Branch, based on the original vehicle scheduling system, also added a camera function to more than 7,000 vehicles, with one at the front and one at the rear. For cameras, bicycles require 1M bandwidth. "Regarding Wuhan's" smart bus "system, Hubei Unicom organized a person to conduct multiple investigations to fully utilize the advantages of the WCDMA network." Yi Fenghua, deputy general manager of the group customer department of China Unicom Hubei Branch, said, "'electronic stop sign', 'smart The construction of information publishing platforms such as "Bus Client" and "Bus WiFi" enable passengers to know the arrival information of buses at any time, and query the real-time location, uplink and downlink directions of each bus anytime and anywhere. "
The "Easy Taxi" software developed by China Telecom facilitates the communication of information between drivers and passengers, alleviating the problem of people taxiing. At the same time, the smart bus system developed by China Telecom has been put into use in many cities. For example, the use of Global Positioning System (GPS) helps bus companies to improve their dispatching and management capabilities, improve the situation of passengers waiting for the bus for too long, and provides a variety of convenient services such as using Tianyi mobile phones to "brush the machine" to take the bus. Played an important role.
