摘要
大力发展自行车交通是优化城市交通出行结构、构建绿色低碳交通体系的有效措施。山地城市受地形地貌所限,城市道路普遍不设计非机动车道,导致自行车交通发展的基础条件欠缺。为解决山地城市道路陡坡不适合自行车骑行的问题,文章提出了一种基于"气流助骑"理念以减小骑行者爬坡阻力的山地城市自行车助力通道,通过自行车陡坡骑行动态受力分析及Matlab数值仿真确定助力通道风速等关键参数取值。风能助力效果实验结果表明:自行车助力通道在4°~12°的坡度条件下助力效果明显。最后,将成果应用于重庆市合川区新建古圣路实际工程项目设计中,为山地城市进一步发展自行车交通和倡导"低碳交通"的出行理念提供了新思路。
The development of bicycle traffic is an effective measure to optimize the urban traffic structure and build the green low-carbon transportation system.Mountainous city is limited by terrain and landscape,thus its urban roads are generally not designed with non-motor vehicle lane, resulting in the lack of infrastructure conditions for the development of bicycle traffic.In order to solve the problem that the steep slope in mountainous city is not suitable for cycling, this article presented a bicycle booster channel in mountainous city based on the concept of＂airflow assisting ride＂to reduce the climbing resistance of cyclists, and through the dynamic cycling force analysis in steep slopes and the Matlab numerical simulation, it determined the value taking for key parameters such as the wind speed of booster channel.The wind-power boosting effect experiment results showed that the bicycle booster channel under 4- 12 gradient degrees has the obvious booster effect.Finally,the achievement was applied to the design of new Gusheng Road construction project in Hechuan District of Chongqing City,which provides a new way for the further development of bicycle traffic in mountainous city and for promoting the concept of＂low carbon transportation＂.
