Abstract

The invention discloses a mobile phone signaling data-based urban transportation characteristic determining method, which comprises the steps of preprocessing mobile phone signaling data and quickly extracting an available field to form a storage format employing a user ID as a key field; sorting mobile positions of each user according to time and carrying out denoising according to a speed and angle exception judgment method; forming a convergence point by using a DBSCAN clustering algorithm, and identifying all stay points and stay time of each user every time; and classifying the stay points and calculating the urban traffic generation amount, the traffic attraction amount, the travel times, the average travel times, the travel distance, the commuting trip distance, the living index and the employment index. The urban traffic generation amount, the traffic attraction amount, the travel times, the average travel times, the travel distance, the commuting trip distance, the living index and the employment index are quickly and relatively accurately calculated by fully utilizing mobile phone signaling data, and data support is provided for urban transportation planning, traffic management and traffic strategy research.

Description

technical field [0001] The invention belongs to the field of traffic planning data analysis, in particular to a method for determining urban traffic travel characteristics based on mobile phone signaling data. Background technique [0002] Urban traffic occurrence, traffic attraction, number of trips, number of trips per capita, travel distance, commuting travel distance, residence index and employment index are important parameters reflecting urban traffic travel demand, and are the scientific basis for traffic planning, urban construction and urban management . At present, with the acceleration of urban construction and the continuous improvement of functions, people have put forward higher requirements for urban traffic planning, construction and management. The traditional methods of obtaining urban traffic occurrence, traffic attraction, trip times, per capita trip times, travel distance, commuting trip distance, residence index and employment index mainly rely on hous...
