浩瀚的海水,翻涌的海浪,一直给广大游人以无尽遐想。可大家有没有想过,如果海洋中的水变成了沸水,将会是一种怎样的景象?敞篷双层观光巴士,是时候说再见了原创2023-06-27 18:50·看看新闻最近,有消息传出,“敞篷双层观光巴士将在今年9月退出市场”,不少市民游客纷纷表示不舍,特地前往观光巴士站点,前去打卡。曾经风靡一时、引领上海城市旅游观光潮流的敞篷双层观光巴士为何要“下线”呢?晚上8点,都市观光旅游线的外滩海关大楼站前,排起了近50米的长龙,不少游客宁愿等上一个钟头,也要坐上自己心中的那辆车。“我大概已经在这里排了一个小时了,一定要坐敞篷巴士。”“我们就想坐敞篷的,之前在上海工作一年了没时间坐。”“以后这个车如果没有了会觉得很可惜,今天特地来感受一下。”游客们纷纷说道。这两天传出的敞篷双层巴士即将退休的消息,让不少市民游客赶着来打卡。上层50多个座位,是乘客们的首选,吹着小风,穿梭各个地标建筑,随手一拍,都是美景。乘客们说:“没有距离感,就感觉是跟整个城市一起移动的,就很好。”“感受清新空气,两边的景色看得更清晰。”目前上海共有8辆敞篷双层巴士,是2010年春秋旅游向汽车厂特地定制,一直以来,可以说不少来上海的游客必打卡的项目,既然如此受欢迎,为何要退出市场呢?春秋旅游副总经理周卫红坦言:“按照规定它要退出行驶,包括它的排放、它的年龄,都有严格的规定,所以到今年应该就是结束它的使命了。那么为什么不再进这样的车型呢,汽车制造行业里,没有敞篷的双层车了,所以我们没有办法买到。”据介绍,按照中国观光巴士使用规定,运营达13年的观光巴士车辆,必须强制报废,不能申请延用。而彼时作为定制的车型,因为国内没有厂家再生产。目前全国还有20多个城市有双层观光巴士,他们中的一些敞篷车型,预计也将在近期陆续退役。复旦大学旅游系教授、国际旅游学会常务副秘书长沈涵表示:“因为国标的问题,双层巴士是燃油巴士,现在有比较严格的一个环保要求,存在一定的安全隐患,包括一些旅客随手扔垃圾等等,现在上海公交对于车辆的要求是封闭式的。”目前公司已着手招投标,计划采购8台环保封顶式的纯电动双层巴士,补上运力缺口。即便市民游客依依不舍,从观光巴士的发展历程来看,求新求变一直是主旋律。2008年,1路观光车出现在上海街头,都市巴士旅游从此开启,不过这条申城第一条双层敞篷观光巴士线一度因客流稀少,最终改成了普通公交线路,变身为188路。到了2010年,上海重启都市观光游计划,春秋等公司再次购买观光车辆,游客越来越多,单春秋旗下的蜻蜓都市观光巴士,就从10辆,发展到了20多辆,到了2022年,响应环保号召,七辆全新的新能源观光车也加入了进来,零排放、零污染、噪音小,游客们的乘坐体验也更舒适。在专家看来,观光巴士紧紧跟随着城市的发展脚步,在当前努力推进“碳达峰、碳中和”的可持续化发展背景下,旅游观光巴士也在不断进行自我升级,未来也应该带来更适合城市特点的旅游服务。复旦大学旅游系教授、国际旅游学会常务副秘书长沈涵认为:“像上海,随着国标五的推出,包括上海对绿色低碳、碳中和这方面的要求,其实是对城市的车辆也提出了一个比较高的要求,越来越多这样历史的人文的,文化遗产、工业遗产的路线也会被设计出来。”目前,都市旅游观光巴士,全市共有3、4家公司运营,在运营过程中,也有游客反映存在车辆到站不停、等车时间久等问题。对此,上海各观光巴士经营公司正着力改进,进一步提升安全和服务质量。春秋旅游副总经理周卫红表示:“也在收集我们的数据,包括游客的反馈,下一步我们会把一部分线路进行优化,既要有市场的呼应,同时也要安全。”近年来,上海的城市旅游项目,一直在不断推陈出新,还推出了“建筑可阅读”、“红色旅游专线”等多种游览方式。市民们可以考虑抓住最后一段时间的机会,来一趟都市敞篷双层巴士之旅。(记者:邱旭黎 摄像:王毅 编辑:由由酱)《监狱风云3国语》高清完整版在线观看-电影频道...
