考虑电动自行车骑行的非机动车道最大纵坡探讨

现行规范要求非机动车道的最大纵坡不超过3.5%，但要在山地城市、跨江桥梁两岸慢行系统衔接等场景下满足该要求存在工程占地大、造价高、可实施性差等问题，考虑到电动自行车在非机动车出行方式中占比越来越高的实际情况，以《电动自行车安全技术规范》（GB 17761—2018）规定的国标电动自行车为研究对象对骑行过程进行受力分析，提出了可满足电动自行车骑行要求的非机动车道最大纵坡参考值，可供电动车骑行占比高的类似项目参考。

Discussion on Maximum Longitudinal Slope of Non-motorized Vehicle Lanes Considering Electric Bicycles

The current regulations require that the maximum longitudinal slope of non-motorized vehicle lanes should not exceed 3.5%. However, there are problems to meet this requirement in the scenarios such as the mountainous cities and the connection of slow traffic systems on both banks of cross-river bridges because of large engineering land occupation, high cost and poor feasibility. Considering the increasing proportion of electric bicycles in non-motorized vehicle traffic, taking the national standard electric bicycles specified in the Technical Specification for Safety of Electric Bicycles (GB 17761-2018) as the research object, the force analysis during the riding process is carried out, and a reference value for the maximum longitudinal slope of non-motorized vehicle lanes that can meet the requirements of electric bicycle riding is proposed, which can be used as a reference for similar projects with a high proportion of electric bicycle riding.
