江苏测试时速200公里级道路，高速公路能否再提速？
<p style="text-align: center;"></p><p><br/></p><p>9月6日，我国时速200公里级高速公路技术在江苏进行了现场测试，实车最高速度一度接近230公里/小时。</p><p><br/></p><p>该测试在高宣高速公路江苏段7.9公里的范围内进行，路段涵盖时速140-160-200公里等多级限速路段。测试车辆8台，其中新能源车辆5台、常规能源车辆3台，从社会渠道招募不同年龄段及不同性别驾驶员8名。</p><p><br/></p><p>此次测试并不是针对汽车性能，而是对道路设计及使用标准进行研究。测试结果规范了对应速度条件下的高速公路平、纵、横段面的设计标准、研发了超高速行驶条件下的新型安全防护措施等，为实现时速200公里级高速公路的安全高效运行提供重要保障。</p><p><br/></p><p>目前中国高速公路行驶速度的上限是120公里/小时，关于高速公路是否应该提速的讨论颇多。此次江苏完成200公里级道路测试，在技术层面奠定了基础。</p><p><br/></p><p>参与测试的交通部原总工程师周海涛表示，在既有常规高速公路时速120公里行驶环境下，基于更加先进的数字交通、新基建技术，应进一步挖掘高速公路通行效率的存量潜能，以满足时速140-200公里的个性化通行需求。</p><p><br/></p><p>德国高速公路发达，部分高速公路不限速，是中国高速公路行业研究较多的对象。2018年德国道路交通事故死亡人数在道路类型上的分布中，郊外公路占57%，城市道路占30%，高速公路占13%。</p><p><br/></p><p>我国即将开通的杭绍甬高速公路，首次在速度层面做出探索。浙江杭绍甬高速设计时速是120公里，但是预留了时速140公里的条件，未来如果要提速不存在技术问题。</p><p><br/></p><p>此外，在江苏高宣高速测试现场还进行了一项磁浮汽车的试验，该技术由西南交通大学研发。磁浮汽车在传统汽车结构上改造，加装悬浮导向用永磁体阵列，并在地面铺设良导体轨道，使得汽车可以悬浮在路面。当天，测试团队实现了悬浮重量2.8吨、悬浮间隙35毫米的试验目标。</p><p><br/></p><section style="word-wrap: break-word;
