某施工单位承接了一座公路隧道的土建及交通工程施工项目,该隧道为单洞双向行驶的两车道浅埋隧道,设计净高5m,净宽12m,总长1600m,穿越的岩层主要由页岩和砂岩组成,裂隙发育,设计采用新奥法施工、分部开挖和复合式衬砌。进场后,项目部与所有施工人员签订了安全生产责任书,在安全生产检查中发现一名电工无证上岗,一名装载机驾驶员证书过期,项目部对电工予以辞退,并要求装载机驾驶员必须经过培训并经考核合格后方可重新上岗。

隧道喷锚支护时,为保证喷射混凝土强度,按相关规范要求取样进行抗压强度试验。取样按每组三个试块,共抽取36组,试验时发现其中有2组试块抗压强度平均值为设计强度为90%、87%,其他各项指标符合要求。检查中还发现喷射混凝土局部有裂缝、脱落、露筋等情况。

隧道路面面层为厚度5cm、宽度9m的改性沥青AC-13,采用中型轮胎式摊铺机施工,该摊铺机施工生产率为80m3/台班,机械利用率为0.75,若每台摊铺机每天工作2台班,计划5天完成隧道路面沥青混凝土面层的摊铺。

路面施工完成后,项目部按要求进行了照明、供配电设施与交通标志、防撞设施、里程标、百米标的施工。

问题:

补充项目部还应完成的其他隧道附属设施与交通安全设施。
