Big data based bus route time table collaborative optimization method

Abstract

The invention relates to a big data based bus route time table collaborative optimization method, and belongs to the technical field of urban bus operation management. Bus GPS (global positioning system) data, bus IC (integrated circuit) card data and route station data are fused and processed into a bus time table to provide actual operation based data support, and a bus time table optimization model considering rail transit transfer is provided. The model takes departure intervals at each time period as decision variables, takes minimum total system cost as an objective function, and comprehensively considers waiting time cost of non-transfer passengers, waiting time cost of transfer passengers and operating cost of bus operating enterprises. Passenger flow data are obtained through multi-source data fusion, a lot of manpower is saved, and accuracy in data is improved. By the consideration of routine bus system and rail transit transfer, reasonability in bus time table preparation is improved. A data model is set up to optimize the bus time table, waiting time cost of passengers and enterprise operating cost are both taken into consideration, and coordination in passenger and enterprise profits is realized.

Problems solved by technology

Liu Huanyu's "Research on Reliability-Based Design and Optimization of Bus Schedules" established a reliability-based bus schedule with the constraints of punctuality, travel time reliability, and service interval reliability, and with the goal of maximizing social welfare. However, there are three main problems in the existing research. First, most of the passenger flow data used are obtained through manual investigation, which not only consumes a lot of labor, but also cannot guarantee the accuracy of the data; second, the research mainly focuses on bus traffic. Third, the research generally takes the passengers at the transfer station as the research object, ignoring the coordination between non-transfer passengers and transfer passengers in the entire line and the relationship between passengers and the bus.
