Embodiment

[0065] In this example, the investigation of commuting behavior in Shanghai is designed. Combining with the current situation of multi-modal traffic development in Shanghai, the four main commuting modes of Parking and Ride (P&R), ground bus, subway, and private car are used for travelers. Analysis of travel behavior.

[0066] Step 1: Pre-survey to collect travel behavior information and carry out pre-processing analysis;

[0067] The pre-investigation adopts two methods of online questionnaire survey platform and on-site one-on-one survey. A simple analysis of the returned effective questionnaires, combined with the communication of one-to-one field surveys, found that it is easier to understand the reliability of travel time in the form of graphics. The actual survey shows that too many numbers and text descriptions will make the respondents ignore a lot of information. Therefore, this project finally decided to use graphics instead of words to directly present the travel ...

Abstract

The invention relates to a multi-mode traffic travel questionnaire survey design method based on D-error efficient-design. The method includes the following steps: 1) collecting travel behavior information; 2) determining multi-mode traffic travel, and selecting a behavior model, influencing factors in the model and parameter level values; and 3), constructing traffic scenes for selection in travel on the basis of a D-Error efficient-design principle, wherein the traffic scenes are used as survey items in a questionnaire survey, and include traffic travel modes with the different parameter level values. Compared with the prior art, the method can effectively improve information acquisition efficiency of SP survey scenes, can obtain more survey information under lower test quantity, has thegreat application advantages for SP survey design of all complex scenes, and has the advantages of originality, scientificalness, practicability and the like.

Description

technical field [0001] The invention relates to a questionnaire design method, in particular to a multi-mode traffic travel questionnaire design method based on D-error effective design. Background technique [0002] Residential travel behavior analysis and demand forecasting are the basis for traffic system planning and traffic system management. Travel mode selection is the most basic choice behavior in travel behavior, and the analysis and prediction of travel mode selection is one of the main contents of transportation planning. [0003] The basic theories of travel behavior analysis include consumer behavior theory, random utility theory and prospect theory. Logit model is the earliest discrete behavior choice model, and it is also the most widely used model at present. [0004] Effective travel behavior data is the basis for analyzing traveler choice behavior and characteristics. The survey method and design method of data collection have an important impact on the ...
