Smartphone-based resident travel information acquisition method

Abstract

The invention relates to a method for acquiring travel information of residents based on a smart phone, comprising the following steps: (1) the mobile phone client detects whether the GPS and the Network are turned on; (2) the mobile phone client uploads user registration information and home / work place to a web server Coordinate information; (3) The web server receives registration and coordinate information; (4) The mobile client collects the latitude and longitude information and time information of the user's track point at a specified time interval and saves them locally; (5) The mobile client automatically uploads the local The stored track point information may be uploaded when the user clicks the manual transmission button; (6) the web server receives the track point data and saves it in the traveler track table in the database; (7) the web server judges the algorithm according to the pre-compiled information and combines POI information, and analyze the travel chain of residents. Compared with the prior art, the present invention has the advantages of wide application range, low cost, simple process and high information accuracy.

Description

technical field [0001] The invention relates to a method for obtaining travel information of residents, in particular to a method for obtaining travel information of residents based on a smart phone. Background technique [0002] Resident travel information is one of the most important bases for traffic planning and design and traffic policy formulation. Resident travel information includes basic personal information of residents, such as: age, gender, household registration, job position, family size, annual income, number of cars owned by the family, etc., and travel characteristic information, that is, travel time, origin and destination, Mode of travel and purpose of travel, etc. [0003] Traditional resident travel survey methods include home visit method, employee survey method, telephone method, etc., requiring trained investigators to conduct door-to-door inquiries and fill in paper questionnaires for collection. The returned questionnaires need to undergo a multi-...

Problems solved by technology

Although this method can solve the problems of questionnaire loss and inaccurate information caused by memory deviation in the manual questionnaire process to a certain extent, it needs to purchase a large number of PDA devices for investigation, and the upfront cost is relatively high.

Moreover, the software still does not avoid the problem of users entering information themselves. Residents need to interact with the system for more complex information at the beginning and end of each trip, which will inevitably lead to data collection omissions due to their own forgetting.

Therefore, although there are many studies on the acquisition of residents' travel information, they lack the consideration of user comfort and do not do enough in spatiotemporal mining of basic data.

The lack of integration of various technical modules to form a convenient and highly automated information acquisition system also makes the travel survey of residents still relatively difficult and cumbersome, which is not conducive to the improvement and management of urban traffic
