Extraction Method of Characteristic Indicators for Travel on the Key Corridor

Based on cell phone signaling data, data analysis methods such as buffer analysis, Tyson polygon, and distance threshold determination were used to establish a matching relationship between base stations and corridors from the perspective of travelers. The method of regression analysis was used to mine the characteristics of travelers' demand and travel behavior. The paper analyzed and established characteristics indicators for travelers. Taking the Beijing–Lhasa Expressway as an example, the method of regression analysis was used to mine characteristics in terms of the basic attributes of the user including the number of trip and the number of trip days. At the same time, this method of regression analysis was used to explore the time characteristics of travelers' patterns including departure time and travel time. And this method of regression analysis was used to explore the spatial characteristics of travelers' patterns including trip occurrence and attraction. The research could provide an important theoretical basis for traffic managers to make decisions.
