Ji'nan's second large-scale public transport information passenger survey starts tomorrow
China Shandong network March 30th (reporter Jia Zhen correspondent Zhao Dongyun) Ji'nan city since the founding of the second mass transit network information passenger flow survey will be officially launched tomorrow. Today, the reporter learned from Ji'nan city bus general company that, since March 31st, the provincial bus department will join the University of Jinan law school and organize 400 college students to carry out a more than 20 day passenger flow survey on more than 180 bus routes in the urban area. The survey includes the investigation of the starting point of the public travel, the delay investigation of the bus travel time, the guests and the guests. The survey and full load rate survey four parts, in order to provide detailed basic data for the bus line network planning and urban traffic demand analysis in the future, and prepare for the layout adjustment of the bus network.
according to Liu Tong, President of the science and Technology Research Institute of Ji'nan bus General Corporation, in November 2006, the first large-scale passenger flow survey conducted by the municipal public transport department investigated about 300000 people and recovered more than 33 million valid questionnaires. The data were processed and advanced passenger flow analysis software was used. According to the needs of passengers, we design a public transit network that meets the needs of the public, ensuring that the public is more convenient and fast to travel. The survey is mainly to investigate the information of the line, to verify the basic status of the bus line, such as line direction, site name, site number and other information, and to make investigation forms. During the investigation, if information changes, the adjustment is changed in time; and bus line information (line direction, length, site name, site compilation) With the combination of Ji'nan geographic information (road trend, name, length, intersection, signal light, etc.), the bus geographic information database is set up to prepare the later modeling. The transit passenger flow survey was led by the operation market department of the bus general company and the Public Transport Research Institute, and nearly 400 outstanding students in the social investigation related to the Law School of University of Jinan were implemented. According to the investigation arrangement, each survey starting point (terminal station) was responsible for 1 administrators. The initial plan is to investigate 15 lines a day and control them at the starting point of 10 surveys.
it is understood that the survey time from March 31st to April 20th, according to the city bus peak hours of 7:05-8:05, combined with the average time for the survey, different lines have different time, the departure time of the survey is usually set at 6:45, 7:00, the main and secondary stations start the same time. The survey used the method of car timing, recording the stopping time, crossing time and the time between the passengers and the passengers. In order to get the delay time at the site and intersection. As a future correction model, damping coefficient is an important factor affecting traffic assignment. Through this investigation, we can obtain the information of the normal bus travel, understand the specific characteristics of the passenger travel flow, comprehensively update and integrate the bus passenger flow data, find the crux of the current bus line network, and lay the foundation for the comprehensive study of Ji'nan bus line network optimization, and then improve the service level of urban public transportation. Enhance the overall image of public transport and facilitate public travel.
at present, the preparatory work for public transport departments has basically been completed, and the whole investigation will start from tomorrow (31). Passenger flow survey was conducted by investigator in vehicle survey, and a questionnaire survey of 50% and a traffic flow survey of 100% were carried out. The investigator of the information survey was composed of nearly 400 outstanding college students from the social survey related department of University of Jinan law school. To this end, the hospital has specially adjusted the course. Every working day's morning peak and late peak, 400 investigators will carry out a survey on the bus with the car, plan to complete a survey of 15 lines a day, and basically cover more than 180 urban bus routes other than the tourist routes.
Ji'nan bus general company also wants to remind the public through this newspaper. This survey mainly uses the car following investigation and the standing point survey. The investigators record the number of passengers, the delay time of import and exit, the delay time of the passengers and the guests, the delay time of the crossing, the information of the trip stop point and so on. In the corresponding form, it may have a slight impact on the public travel. Therefore, we invite the general citizens to give understanding. According to the regulations, investigators carry out on-site investigations only on buses and need to wear survey certificates, so the general public can cooperate with each other.
