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

Abstract

The embodiment of the present invention relates to a method and system for estimating commuter distribution of urban rail transit, which extracts traffic travel transaction records within a time period T, and extracts commuters; calculates the travel information of each commuter, and constructs a portrait of each commuter; based on The portrait estimates the commuting distribution of the commuter group; every specific time period T0, extracts the traffic travel transaction records in the time period T0, and extracts the commuters; If the similarity does not exceed the set threshold, the portrait will not be updated; otherwise, the portrait of the commuter will be updated; for commuters who do not have a portrait, use the data in the time period T to recalculate the travel information of the commuter to construct the commuter portrait of the person. The invention extracts commuters, constructs portraits for commuters and updates them regularly, and estimates commuting distribution based on the portraits, with accurate estimation and less 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 passenger commuting travel, that is, public transit OD is of great significance for the planning and operation management of the bus system. . [0003] Commuter traffic is the main part of the city's morning and evening peak passenger flow, attracting commuters to choose public transportation for travel plays an important role in alleviating urban traffic congestion. Obtaining the commuting OD distribution of passengers can analyze the characteristics and laws of public transportation travel demand, and master the characteristics and laws of commuter public transp...
