双碟刹安全征服城市通勤路?

作为维修界二十年的"老蜗牛",最近总被年轻人追问那款挂着宝马标的变速山地车——那双碟刹咬住地面的狠劲、镁合金轮组透出的科技感,还有变速系统行云流水般的切换,确实颠覆了很多人对自行车的传统认知。今天咱就拆开这辆"城市探险家"的机械骨骼,看看那些藏在炫酷外表下的精密机关。

哪些交通安全知识需牢记?

交通安全关系千家万户提升自我交通安全意识养成文明交通行为至关重要遵守交通规则不仅关系到自己的生命财产安全同时也是尊重他人生命的体现时刻牢记交通法规遵守交通规则从自身做起,从小事做起让“平安大道”畅通无阻,自觉遵守交通规则在有交通灯的地方要做到红灯停、绿灯行不在马路上使用滑板车、轮滑平衡车等各种代步工具不在马路边、公路上机动车出入口或车辆盲区内玩耍打闹

电动自行车车主必看的哪些知识?

电动车起火的原因很复杂,自身线路老化、电池短路、充电器不匹配、过度充电都可能造成起火,比较而言,电动车充电时风险最大。不同型号的电动车需要配置不同电动车充电器,且不能混用,劣质充电器、不匹配的充电器都是火灾隐患。

如何设置自行车道?

我国是自行车大国,但相应管理设施的技术,还有很大提升空间,特别是笼统地将自行车在法律层面归纳于非机动车,在技术分类上归纳为慢行交通,给自行车的使用和道路设计带来很多问题,进而影响道路交通秩序,破坏交通流的流畅性与安全。笔者借鉴西方国家的技术资料,梳理一些值得思考的知识点,重新审视设计自行车道和电动自行车道的对策。

对自行车交通流有哪些要求?

自行车应一辆接一辆跟随前进,前后对齐的队列可以有偏差,偏差距离一般在20-80公分,不是一窝蜂在宽车道里你追我赶往前抢行。特别是在路口,要能让其他人预测到每辆自行车的运动轨迹。因为只要是动态交通流,而且运动有持续的速度,人与人的行为差异就会被速度放大,人的判断能力和处置危险的能力就受到挑战,人与人之间的互动就要有提前量,就要借助交通控制措施来进行提示、控制和积极引导。

自行车道的基本宽度是多少?

西方国家普遍定义的骑车人基本轮廓需要1.0米(40英寸)的基本操作空间(包括车把和前轮扭动时需要的空间)。在通常情况下,美国以1.2 米(4 英尺)的操作空间定为任何自行车专用道或者是骑车人喜欢用的车道的最小有效宽度,无论硬路肩还是专用自行车道,都是这个数值。如果机动车流量大、机动车或骑自行车的速度高,以及大货车和公共汽车的混合交通量增加。

自行车道有哪些类型?

自行车道的类型选择取决于许多因素,包括道路用户的能力、特定的走廊条件和设施成本。用户能力不仅指技能,也包括身体条件、时间和其他条件等。很多发达国家对自行车道的分类方式不同,但基本逻辑相同,即根据使用目的、路权、技术条件和设施水平划分。以下介绍美国关于自行车道的分类方式。

自行车路径标识型共享道路?

共享道路上的自行车路径指引标识有很重要的意义,不仅可指示目的地,也可提示骑车人,相较其他路径,本路径有更利于骑行的特定条件;同时告诉用路者,道路管理方在路上为骑行做了专门工作,以确保其更适于机动车和自行车共同使用,另一方面,也提醒过路的机动车驾驶人,路上有自行车骑车人。
