Improved SP-off-RP Survey Method and Its Application to Mode Choice Model

With the fact that traditional aggregate traffic demand model is unable to meet the requirements of transportation planning, researchers have introduced the disaggregate model into the application on transportation choice behavior modeling. The most two frequently used survey methods providing data for model estimation are revealed preference (RP) and stated preference (SP) survey, and each has its advantages as well as disadvantages. A complementation between them used by a joint survey method called SP-off-RP method has been proposed afterwards. An effort is made to improve the survey method of SP-off-RP method. The improved SP-off-RP method is applied to the data collection work supporting a transit mode choice model by conducting an interactive survey on a website. The data is then analyzed in the parameter estimation for the discrete choice model. The results show that this method requires fewer subjects in survey while acquiring more data to obtain a more accurate result.
