Title   Flow Distribution Characteristics of lane in  highway  traffic persion area
Abstract
In the backdrop of the rapid development of the highway in our country, the research of highway vehicle data get the more and more attention of the domestic scholars.
Highway triage area as an important part of highway, bears the weight of the vehicle shunting action of the highway. However,the in-depth study of highway persion area is countable in our country, and the researches on flow distribution characteristics of lane for persion area of are much rarer. Exploring this area is helpful of improving the highway traffic investigation and  planning of the highway persion area.
This article is based on probability statistical model. Through the analysis of survey data, we determine the research section of each lane fitting distribution model of vehicle distribution characteristics and point out the deficiency of the method in the research.

Keywords  Highway  Diversion area  Flow distribution of lane
