远程操控红绿灯,老的拥堵路段变通畅了

智能交通控制系统集多种功能于一体。

在渝中区生活了多年的许先生最近开车经过两路口环道时,发现了一件“怪事”:无论环道的交通是堵车还是通畅,常常看不到有民警在路口执勤。但要是有车祸或是其他事故,交巡警很快就会出现。

许先生对此感到有些不解,“两路口环道以前堵车很严重,虽然现在情况好了很多,但也不至于没有民警执勤吧?”

智能交通系统集纳多项功能

前天上午10点,重庆晨报记者在渝中区公安分局交巡警支队的指挥大厅里,为市民许先生找到了答案。

指挥大厅中央的几十块监控屏幕上,是渝中辖区内各个重要路口的高清监控摄像头所捕捉的实时画面。这些实时画面中都有一个共同的特点:见不到一个在路面执勤的民警。

这正是渝中区的智能交通控制系统,该系统集多种功能于一体,具有移动警务、指挥调度、交通诱导、交通组织、视频管理、违法处理、统计分析等多项业务功能。

据渝中区交巡警支队相关负责人介绍,目前渝中区的灯控路口共99个,现在联网的路口已达到了100%。和传统红绿灯控制最大的区别,就是实现全后台操作,不再像以往,还需民警前往现场对红绿灯的变换进行手动操作,大大节省了操作时间。同样,也不需要民警24小时在现场执勤了。

拥堵路段交通状况大幅改善

渝中区交巡警支队指挥中心主任杨杰告诉记者,他们仍要保证随时有50多名交巡警在路面上,一旦路段出现紧急情况,按照指挥中心的调度,将以最快的时间赶到现场。同时,在一些新形成的“堵点”上,依旧需要民警执勤。

杨杰介绍,传统城市交通管理模式已经不适应当前交通需求,加之渝中区本身的特殊环境和地理因素,更是成为了城市道路交通的发展瓶颈。发展智能交通是解决渝中区城市交通问题的最佳良方。

他说,智能交通让以前一些老的拥堵路段、路口的交通状况得到了大幅度的改善。例如,两路口环道,车辆多、交通压力很大,以前平均要保持有三到四个民警在环道巡逻,才能保证通畅。而现在基本上不需要民警在现场了。

交通违章数量大大下降

是什么让交通违章数量大大下降?渝中区交巡警支队相关负责人介绍,这依旧是智能交通的功劳。违法变道抓拍系统就是利用路面交通标志的实线作为抓拍器的虚拟线圈,一旦有车辆碾压,便会触动快门自动拍照。而被抓拍的车辆违章信息会经过民警人工验证确认后再录入系统。

■成效

渝中区主干道

行车速度显著提高

数据显示,今年下半年以来,在石黄隧道、嘉华隧道、渝澳大桥、马家堡袁家岗路口等进出渝中的主干道上,平峰期正常车速较以往提高了10公里/时左右。而在临江门地区,通过实行智能交通改造,路口通行能力由以前的每小时4000余辆急速扩大到每小时6000余辆,早晚高峰平均缩短30分钟,高峰时期车速平均提升约27%,区域出行更加畅通。
