The invention discloses a method and device for analyzing the service range of an expressway interchange, which can analyze the service range of an expressway interchange based on mobile phone data. The method includes: S1. Acquiring the mobile trajectory data of multiple users from the mobile phone signaling data, and extracting from the mobile trajectory data of the multiple users the users who have passed the specified expressway section within at least one specified time period S2. For the extracted mobile trajectory data of each user in each specified time period, calculate the travel origin and destination points of the user in the specified time period, wherein the travel origin and destination points include the expressway The starting point and destination of the journey of the segment; S3. Calculate the total service range and each sub-service range of the expressway interchange in each specified time period according to the travel origin and destination.
Description
technical field [0001] The invention relates to the field of traffic planning data analysis, in particular to a method and device for analyzing the service range of expressway interchanges. Background technique [0002] Expressway interchange refers to the intercommunicating modern land bridge established at the intersection of two or more expressways, which is layered up and down, runs in multiple directions, and does not interfere with each other. The correct planning and design of expressway interchanges is a very important part of expressway design. As a basic transportation facility connecting various regions, the service scope of interchanges is not only an important basis for the planning and construction of expressway interchanges, but also a key factor in later project evaluation. The existing analysis of expressway interchanges mainly uses traditional OD survey data or video data to study the traffic volume and operation status of expressway or urban expressway in...
