Beijing, the capital of China and a well-known historical city of the world, is the center of China’s politics, economy, transportation and culture. Up to the end of 2007, the city’s permanent resident population reached 16.33 million, with an urban area of 87.1 square kilometers. The city enjoys a widespread transport network of highways, railways, airlines and public transit.
The city’s old urban area (within the 2nd Ring Road) is of a chessboard pattern, combining with horizontal and vertical roads. In the outer city, the road pattern is circular and radial. The city’s projected highway traffic network is comprised of five ring roads (the 2nd, 3rd, 4th, 5th and 6th Ring Roads) and 15 high-speed connecting lines.
By the end of 2007, Beijing’s highway had reached 20,754 kilometers, of which 628 kilometers were expressways, 768 kilometers were first class roads, 2,799 kilometers second class roads, 4267 kilometers third class roads and, 12,073 kilometers fourth class roads. Highways in the eight urban districts reached 4,460 kilometers, of which 236 kilometers were expressways, 960 kilometers were trunk lines, 694 kilometers sub-trunk lines and 2,570 kilometers side roads and resident area roads.
Conditions of motor vehicles and drivers
By the end of 2007, the city’s total volume of motor vehicles hit 3.13 million, of which 2.36 million were private motor vehicles; 5.48 million were non-motor vehicles, of which, 4.61 million were bicycles and 470,000 were electric bicycles; drivers number hit 4.55 million.
Beijing’s traffic facilities have continued to grow in these years. By the end of 2007, the city had installed 120,052 traffic signs and 2,747 traffic lights. Traffic marks had reached 13,432 kilometers, 513,738 meters of guardrail had been set up, 217 kilometers of lane had been set specially for public transit use, and 4,847 commercial parking lots had been set up and could accommodate 1,073,886 motor vehicles.
Beijing has 900 to 1,000 public traffic routes for tramcars, air-cooled buses and double-deckers. Most of the motor vehicles use low-emission liquefied petroleum gas and natural gas. In 2005, Beijing completed the renewal of buses and tramcars. Now Beijing’s public transit is the busiest one in the world and transports the largest number of passengers.
To realize the goal of making Beijing’s traffic management among the most advanced in the world and first class in China, the Beijing Traffic Management Bureau, under the general framework of intelligent traffic control, sticks to the concept of “with demand as orientation, with application as core, with management as guarantee, with innovation as precondition, with quality as the foundation,” and has carried out in a comprehensive manner the programming and construction of an intelligent traffic management system. Now the intelligent traffic management system has been initially completed whose core is based on the data center, and is supported by three platforms of traffic command, information management and information release. Thus modernization in traffic control, digitalization in management, networking in information and automation in office work have been achieved.
The establishment of an intelligent traffic control system has greatly enhanced the capacity in macro traffic control, traffic command and coordination in face of emergency, and has promoted the tremendous development of the overall level of traffic management, and has played an extremely important role in improving traffic order, ensuring traffic safety, alleviating traffic jams and constructing a harmonious traffic environment
