Contrast and choice of pedestrian bridge and pedestrian subway

Through analysis of the users' psychologies,climate condition,society benefit,economic benefit,sight condition and construction condition,AHP(Analytic Hierarchy Process) is proposed to select and set the pedestrian or pedestrian subway.Takeing a section of a highway in Harbin for example,this study establishes the structure of the AHP and the judgement matrix of each element,calculates the relative weight,and then compares to set up, as a result,it passes the coherence test.
