近年来,中国城市机动化高速发展导致了大量的城市交通问题,继而引发道路交通规划与建设也出现了许多问题,不少地方政府开展了"治堵"的行动以改善地方性交通组织,但收效不大。通过文献整理、案例研究和规划实践发现,仅依靠单一的路网微循环发展模式并不能解决现今越来越严峻的交通问题。结合"浙江省丽水市北城多模式交通微循环研究"项目的编制,通过对城市交通系统的改善和局部调整梳理,实现多模式下的交通微循环系统,梳理总结出"交通微循环的效果实现,需要依赖于多模式交通方式的有效整合,大力提倡公交优先"的结论,希望这种模式能成为针对中小城市交通问题行之有效的解决方式,为未来的相关交通规划工作提供参考经验。

舒群在抗日战争时期的创作中,不仅通过描写各种象征符号的争夺展现了沦陷区各族人民民族国家认同的觉醒和高扬,还藉由对流离彷徨的异族弱者满怀同情的书写,彰显了源自底层生活和殖民经验的兼具阶级意识、民族自觉和人道精神的国际主义立场。这种生发于族群、阶层、地域三重边缘身份的国际主义,是舒群之于抗战文学乃至中国现代文学的重要贡献。
