Abstract:It is helpful to grasp the overall travel rules of public transport more accurately and better meet the travel needs of passengers to obtain the travel behavior characteristics of public transport commuters from the perspective of individuals. Based on the public transport card swiping data and line station data, by use of the representation advantage of graph visualization of public transport commuters, the travel graph construction method of public transport commuting trip was studied, which took the horizontal axis as the time series axis, the vertical axis as the position axis, and the node size as the direction angle. On this basis, the method of structure similarity combined with the longest common subsequence was used to realize the similarity identification of graph, which selected attribute indicators such as travel mode, direction, time and route. Taking the one-week public transport travel data of individual passengers as an example, the rationality and validity of the research results were verified. The research results can intuitively reflect the individual travel process, which provides a new idea for the expression and extraction of trip characteristics.
