Description

机动车礼让指示器 技术领域
本发明机动车礼让指示器，涉及的是一种行人或非机动车安全指示器，尤其是在十字路口或斑马线处，当机动车驾驶员做出礼让行为时，礼让指示器自动在车外以声光形式提醒行人或非机动车，机动车驾驶员正在礼让，请放心通过的车外指示器。
背景技术
随着机动车在中国保有量的不断提高和社会主义核心价值观的不断深化，机动车驾驶员主动礼让行人和非机动车正成为一种文明美德。
但根据宁波晚报2016年7月16日的报道，仅前一个月，交警开出了近3000张机动车未礼让班马线的违法行为处罚单。据新京报2016年7月15日报道，温州乐清市为了倡导机动车礼让行人，采取了营运车辆司机主动礼让行人每次可获100元，但效果堪忧。对于中国2015底的机动车保有量2.79亿比较，新闻报道的数量毕竟是少数的，事实上大部分司机在路口和斑马线处能主动礼让行人和非机动车。但由于少数机动车驾驶员不礼让行为的存在，使行人和非机动车驾驶员在路口或斑马线处无法预测远处驶来的机动车会礼让还是直接快速驶过，从而在路口存在犹豫徘徊的现象。与此同时，机动车驾驶员也无法预测行人或非机动车会在路边停止还是直接往道路中间移动。上述二种现象均会导致双方沟通障碍，最终使道路交通流量下降，更严重甚至会引发交通事故。
