Study on Walkability Factors and Optimization Strategies of Footbridge Slope from Perspective of Environmen-tal Praxeology
As an important link in today's urban waterfront landscape,the footbridge has been widely constructed in various regions.It is an important walking carrier in the city,and its own walkability level has important value.And the comfort design represented by the slope has the most significant impact on it.From the perspective of environmental praxiology,the slope design of the footbridge should take into account the balance between the psychological perception level and the physiological perception level,which is of great value to the walkability of the footbridge.Based on the multi-objective optimization strategy of Pareto optimality,the comprehensive optimization at the psychological and physiological levels can be translated into the optimization of the length of the straight section and the length of the steep climbing stage respectively.By using parametric means,the bridge slope is decomposed into point-by-point slopes,and an optimized path and method to achieve the highest level of walkability are comprehensively proposed.
