Most of the urban transportation planning use the four-step method to forecast traffic volume in China. The first step of this method, urban trip generation, is based on large-scale investigation of urban resident trip presently. But in new or future urbanizing area, due to the lack of investigated trip generation information, trip generation meet problems. So it's necessary to find another method to forecast trip generation in this kind of situation. According to the research from America Transportation Engineering Institute, though different type of land has different activity character, reeving regularity character, and function character, trip generation is regular depending on land usage type. This paper discuss how to get the trip generation rates based on the properties of land use in Xi'an, one of the Chinese city, referring classifying land usage type, demarcating zone of investigate, calculating trip generation rote and Application in Xi'an trip generation. This research can be used for reference to trip generation in other Chinese cities.
