近日，有多位热心听众向我们新乡交通广播《出行在路上》节目组反映：市区十字路口分流岛内所设置的隔离墩让三、四轮车的通行多少有些不便。 Recently, a number of enthusiastic audience to xinxiang our traffic radio: "travel on the road you're shunt the island city intersection set isolation pier let three popular somewhat inconvenient, carriage. 那么起到分流引导非机动车和行人通行的隔离墩间距有多宽？规定设置间距为多少？实际通行起来又是否会带来不便呢？ How wide is the spacing between the non-motor vehicles and pedestrians? What is the spacing? Is it inconvenient to actually travel? 隔离墩 Isolation pier 十字路口 The crossroads 分流岛 Shunt island 站在路口，记者目测间距应该在1.5米左右。经亲测，两隔离墩内并列过1辆三轮+1辆两轮不成问题！ Standing at the intersection, the reporter's eyeball should be about 1.5 meters apart. Through affinity, two separate rounds of the two separate blocks are not a problem! 那么间距具体是多少呢？来看看市政设计研究院的专业人员给出的解答： So what is the spacing? Check out the answers from the experts at the municipal design institute: 城市道路设计规范 Urban road design specification 设计依据 Design basis 分流岛设计图 Shunt island design 隔离墩设计图 Isolation pier design drawings 隔离墩 Isolation pier 来自新乡广播电台 From xinxiang radio station 00:00 00:00 00:45 00:45 市政设计研究院黄东升： Huang dongsheng, the municipal design institute: “ " 城区十字路口分流岛内的隔离墩按要求设计的净间距为1.5-1.8米（具体依照所属地段路况调整）。依照《城市道路设计规范》设计规定：行人通行间距约为0.75米，自行车通行间距约为0.6米，三轮车（含电动）通行间距约为1.25米。因此，1.5-1.8米的隔离墩间距理论上可以满足所有的非机动车通行需求，之所以通行过程中会有市民会感觉间距过窄，很有可能是以拐弯状态（非直行通过）所致。如果继续拉大间距，则起不到隔离机动车的作用。 The intersections of the city's intersections are designed to be designed with a net spacing of 1.5-1.8 meters (depending on the location of the location). In accordance with the provisions of the specification for design of urban road design: pedestrians distance is about 0.75 meters, cyclists distance is about 0.6 meters, tricycle (including electric) travel distance is about 1.25 meters. Therefore, 1.5-1.8 meters isolation pier spacing can meet the demand of all the non-motorized traffic in theory, in the process of the traffic will be too narrow, the citizens will feel spacing is likely is caused by state (not straight) through a corner. If you continue to widen the gap, you will not be able to isolate the vehicle.
