Problems solved by technology
Traditional public transport travel information is generally obtained through large-scale resident travel surveys, which has the disadvantages of high cost and short data life cycle
The lack and lag of decision-making information make it difficult to adjust the bus network planning and bus operation plan in accordance with the dynamic changes in travel demand

The embodiment of the invention relates to an urban rail transit commuting distribution estimation method and system, and the method comprises the steps: extracting traffic travel transaction records in a time period T, and extracting commuting personnel; calculating travel information of each commuting person, and constructing a portrait of each commuting person; estimating commuting distribution of the commuting personnel group based on the portrait; every other specific time period T0, extracting traffic travel transaction records in the time period T0, and extracting commuting personnel; for the commuting personnel with the portraits, calculating the similarity between the commuting personnel with the portraits and the travel information in the previous time period T of the time period T0, and if the similarity does not exceed a set threshold value, not updating the portraits; otherwise, updating the portraits of the commuter; and for the commuting personnel without the portraits, recalculating the travel information of the commuting personnel by using the data in the time period T to construct the portraits of the commuting personnel. The method extracts the commuting personnel, constructs the portraits for the commuting personnel and updates the portraits regularly, estimates the commuting distribution based on the portraits, and is accurate in estimation and smaller in calculation amount.
Description
technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and system for estimating commuting distribution of urban rail transit. Background technique [0002] The analysis and prediction of passenger travel demand is the basis of urban rail transit operation organization. Accurately grasping the origin (Origin) and destination (Destination) of bus passengers commuting, that is, bus commuting OD, is of great significance for the network planning and operation management of the bus system. . [0003] Commuting traffic is the main component of urban morning and evening peak passenger flow, and attracting commuters to choose public transportation plays an important role in alleviating urban traffic congestion. Obtaining the commuting OD distribution of passengers can analyze the characteristics and laws of commuter travel demand, and mastering the characteristics and laws of commuters' bus travel demand is the ...
