摘要
步行指数作为一种有效的量化测度步行性的方法,对优化城市日常生活设施布局,提高居民出行便利度,改善人居生活环境影响显著。扬州市将提高步行指数作为构建城市慢行系统的关键,力争每条街道步行指数在70分以上。文中在国内外现有步行指数模型的基础上,考虑公共交通对居民出行的影响,从安全性和舒适性2个角度出发,适当调高公园、公交等设施的权重,使之更契合扬州居民出行习惯,同时引入绿化水平参数,对模型进一步修正。利用改进后的模型对扬州科创新城现状步行指数进行测算,并对采用不同优化措施前后的步行指数变化进行对比分析。提出采用用地混合设计及公交引导开发(TOD)是最能提高街道步行指数的措施。
As an effective quantitative measure of walkability,walk score has a significant impact on optimizing the layout of urban daily living facilities,improving residents'travel convenience and improving the living environment.Yangzhou will improve the walk score as the key to building an urban slow traffic system,and strive to make the walking score of each street more than 70 points.Based on the existing pedestrian score models at home and abroad,considering the impact of public transport on residents'travel,the weight of parks,public transport and other facilities should be appropriately increased from the perspective of safety and comfort to make them more in line with the travel habits of Yangzhou residents.At the same time,the greening level parameter is introduced to further modify the model.The improved model is used to calculate the current walk score of Yangzhou science&technical new town,and the changes of walk score before and after different optimization measures are compared and analyzed.It is proposed that mixed land use design and bus guided development(TOD)are the most effective measures to improve street walk score.
