Early November, China-Africa Cooperation Forum Beijing Summit held during the temporary implementation of traffic control measures to Beijing, hundreds of thousands of buses and private cars not on the road, a large number of people traveling with the flow of public transport, buses take to ensure smooth flow of vehicles and passengers easy and quick task. How to not only protect the roads open, passengers backlog phenomenon? Scientific control seems to Beijing Public Transport Holdings (Group) Co., Ltd. (hereinafter referred to as "Beijing Bus Company") the only option.
BRT Bei Shi Min "Ji Bao"
It is understood that during the Beijing Summit of the automatic bus company office OA systems are all open, the main business of information dissemination, internal communication with a sound platform for the summit from the technical information to ensure smooth. The intelligent bus scheduling system and last year just in South Central from Zhengyangmen to Demao Village Bus Terminus opened the BRT line of dedicated bus rapid transit line which is a special role to play.
South Central BRT bus lanes in the middle of the road there
BRT Bus Rapid Transit system is a light rail transit and bus transport between the new operating system between its use of modern bus technology and intelligent management of traffic operations, can bus to light rail fixed departure, fixed departure and arrival, fixed Back to the field of basic functions and services, and its investment and operating costs low off than light rail.
According to deputy director of Institute of Beijing Public Transport forest is introduced, BRT system mainly has the following characteristics: ① the exclusive right of way: through the use of closed or relatively closed bus-only lanes or bus lanes (divided into the middle of the road and the Road margin of two) to obtain the exclusive right of way transit system, improve the independence of the public transportation system, to ensure the rapid operation of the system of service standards.
② modern high-capacity vehicles: single or double hinged access large-capacity buses, with a total length of 18-25 meters, can be carrying 200-300 people, the use of advanced suspension system, with safety, comfort, environmental protection, human features.
③ by reducing the level: low chassis and high single-spliced, or twisted-pair access platform that complements public transport vehicles, pedal to the train station and the high flush, rapid and smooth on the passenger can get off to shorten the hours of operation, to facilitate young and old disease disabled car.
④ vehicle ticketing: Ticketing System Settings in the bus station waiting areas, the use of automated or semi-automatic electronic toll system, buses stop in the process before the completion of charging, improve operational speed.
⑤ advanced intelligent management: use of information technology operations to grasp the dynamics of vehicles using the intelligent, data, information management, on the vehicle during operation command of the implementation of dynamic real-time scheduling.
South Central Bus Rapid Transit lanes of Beijing plans to build not only the four first of bus rapid transit line, and become the country's first Bus Rapid Transit. Because BRT vehicles can pass, along the eight bus lines have also been withdrawn, and the traffic lights are to be released along the way, one-way traffic down just three to four minutes faster than usual on the buses to several minutes, opened the first Japan came close to being public, "clogging."
Intelligent system with the BRT
"South Central Bus Rapid Transit line is equipped with a set of relatively complete intelligent scheduling system, currently used computer and artificial combination of daily schedule." Forest is introduced.
Compatible with the rapid transit line intelligent scheduling system needs to needs of several subsystems, including this: ① start bus rapid transit planning and scheduling system. Dispatch center through the coil and the station's surveillance camera system to automatically identify and stop vehicles and stop time manually set the start time.
Departure time of vehicles, with car, bus information with class schedule grid has entered the dispatch center intelligent scheduling systems, scheduling systems, expert systems simulation technology can help automate the scheduling of vehicles. South Central rapid transit lines in operation has been achieved when a low peak level of computer automated dispatch, made a few minutes a train, which the driver a few basic grid scheduling information can be automatically conveyed to the station, the station display Tips on time and passengers can start. South Central rapid transit lines at peak time, other lines are also used combination of computer and manual scheduling options to deal with complex traffic.
② vehicle location and communication subsystems. Vehicle location system control center monitors traffic through the run way in the state of exception occurs when the vehicle, the driver-vehicle communication system through contact with the dispatch center. Southern Axis BRT Line vehicles equipped with mobile phones and GPS global positioning system, the key use the car phone to exchange information with the dispatch center, dispatch center can monitor the operation of the vehicle. If the road in case of congestion, control center can immediately understand the message, through the deployment range of cars and other operation mode immediately be resolved.
③ station CCTV subsystem. Monitoring stations for ticketing, passenger flow, and other unusual situation, when abnormal, the control center through communication systems and command. Southern Axis BRT Line station entrances and exits of vehicles to install a smart card reader bus access points, card readers can be automatically read vehicle information, and through an integrated system dedicated to the news reached the dispatch center system. The first terminal station and TV monitor are promptly recorded the admission of the video data bus station, dispatching center for the Taking.
④ intersection rapid transit signal priority control subsystem. When rapid transit through the green lights, lights buses equipped with automatic identification system can quickly become a green light signal, bus priority through the intersection.
⑤ passenger information subsystem. The rapid transit lanes on the platform are equipped with electronic equipment for passenger check by check, the number of passengers to understand the site, site name, the next train for departure time interval of many minutes and so effective and immediate information.
Great advantages of low cost accounts
Southern Axis BRT Line opened the third day after - on January 1 this year, passenger traffic reached 1.2 million; close to the end of August this year, the cumulative transport of passengers has reached more than 2017 million, to around 35% along the Passenger attracted over.
It is understood that Bus Rapid Transit BRT system, the investment is relatively low, about 020 million yuan per kilometer to 100 million yuan, much lower than 600 million yuan per kilometer subway to 800 million yuan of investment, the amount of view from the passenger transport , BRT system and LRT almost all the same. And from a comparative perspective, BRT system, the shortest construction period, usually 1 to 2 years. High-capacity transit system from the construction period, construction costs, service level view of all have incomparable advantages in line with Beijing's construction of a modern city needs.
Southern Axis BRT Line opened, the integration of the seven traditional overlapping bus lines, removed more than 200 buses to reduce a lot of energy consumption and operating costs, so that the road has also been a scientific and rational resource utilization.
This year in March, Beijing Traffic Development Research Center of the survey data: 90% of the passengers that the bus rapid transit line to save travel time, that the waiting time short account for 80% of the passengers.
By 2008, Beijing will be completed at least 60 km of rapid transit lines, in addition to the current operation in the South Axis, including Anli Road, Chaoyang Road Bus Rapid Transit line. Tsinghua University Traffic Institute, Professor Shi Qixin told reporters, according to the vision of rapid transit in Beijing will be completed within 20 years 200 km of rapid transit line network, that time, Zhongguancun, Beijing Third Ring Road and other well-known traffic crowded roads, bus rapid transit line will be the construction of a large part of the current private car trips take passengers will be attracted to the fast and convenient to buses.
