The promotion of smart public transportation system is the development direction of China's urban public transportation system to cope with the increase of urban population, improve operational efficiency, and sustainable management. The 26th China University Games was held in Shenzhen this year. The bus system promoted by the Shenzhen Bus Group is a good example of the future of urban public transport systems.
Three measures of intelligent operation of public transportation system
First, visual monitoring. Through the installation of 5-way camera video monitoring equipment in the carriage, it can control the road conditions in front, the waiting conditions of the passengers on the platform, and the full load of the carriage. At the same time, with the help of car voice communication equipment, the driver can communicate with the dispatcher in a timely manner, respond to emergencies, and respond in a timely manner.
Second, real-time passenger flow statistics. The light curtain sensor is installed directly above the front door and rear door of the vehicle to acquire real-time and offline passenger data in real-time and perform chart analysis to implement flexible transportation according to changes in passenger flow.
Third, passenger flow analysis. Through the establishment of the bus line Shenzhen Tongsuo card database, the bus lines, basic operational information (to, departure time, etc.) and Shenzhen Tongtong basic card information (passenger card number, line number, credit card date, credit card time, car number, etc.) are extracted. The mathematical probability model was used to calculate the traffic volume of the line throughout the day, the number of people on board at each site, and the number of people on board at each peak hour.
Five transformations complete the intelligent upgrade of vehicles
For this reason, Shenzhen Bus Group, based on the current status of domestic passenger car design and based on fully researching and studying vehicle safety standards in Europe and the United States, has continuously practiced and summarized and established the first vehicle safety facility configuration standard in China to improve the current vehicle safety facilities, and finally it is reflected in The vehicle configuration standard. There are:
First, China's first air-conditioned emergency escape window. Bus Group and bus manufacturer jointly developed the first emergency escape window for vehicles in China, effectively solving the contradiction between the fully sealed structure of air-conditioned cold windows and vehicle emergency escape.
Second, the application of high speed communication CAN bus. The application of CAN bus is based on the requirements of safety, comfort, convenience, low pollution, and low cost, and it is put into use in order to adapt to "reduction of the number of harnesses" and "high-speed communication of large amounts of data through multiple LANs." , is one of the active safety settings for vehicles.
Third, ABS anti-lock braking system. The ABS system keeps the vehicle in rotation while braking, helping the driver to control the vehicle to a safe stop. At present, the proportion of ABS systems operating in the bus group is gradually increasing, which has become the standard for new vehicle technology deployment and greatly improves the safety of vehicle driving.
Fourth, the brake gap automatic adjustment arm . The brake gap automatic adjustment arm can automatically and timely adjust the gap between the brake lining and the brake drum due to the brake wear, so that the brake gap is constant. The bus group vehicle has fully equipped this equipment and is also a standard accessory for the purchase of new vehicles by our group.
Fifth, aviation wire. Aviation wires should not burn during testing, or the speed at which the flame is transmitted on its surface should not exceed 102 mm/min. In addition, or within 60 seconds after starting the combustion, the material prevented the combustion and the flame did not advance beyond 51 mm. This standard greatly reduces vehicle self-ignition caused by harnesses .
It is reported that at present, a number of active safety facilities for public transport vehicles, such as aviation conductors and CAN bus control systems, are widely used within the bus group, which greatly increase the technological content and safety factor of vehicles, and are the trend and direction of future bus development.

The functional characteristics of the information-based intelligent public transportation system:
Effective data management and analysis capabilities, including operational data management and analytical data management. Its purpose is to ensure the efficient management of daily operations, scientific decision analysis of planning and scheduling, and to provide the public with high-quality information consulting services. The real-time system status query and historical data analysis services provided by the managers support the decision-makers in formulating macro-information analysis of traffic development policies and plans. This task is mainly completed by the Public Transport Information Center.
It has the ability and means of collecting basic data for public transport operations to ensure the data source basis of the system. These basic data include: traffic demand data mainly based on the number of passengers on the bus station, bus speeds and station stop time data, and vehicle driving status data. Taking into account the particularity of bus operations, the collection of these data is mainly undertaken by the onboard subsystems of public transport vehicles.
