What is the freeway management system
Since the mid 1990s, ITS has been a key part of the regional freeway system. ADOT’s Freeway Management System includes technologies and systems that help to improve the flow of traffic on Valley freeways, provide information to motorists about crashes or construction, and help ADOT and other agencies better respond to traffic incidents.
You can see ITS working on freeways every day.
Some of the technologies that you see on freeways in the metro region include:
Ramp Meters – These signals at freeway entrances regulate the timing of vehicles merging on to freeways. Ramp meters operate during the morning and afternoon commute times. Some entrance ramps have one ramp meter signal, others have two, one for each lane, that allow alternating vehicles to enter the ramp.
Regulating the flow of traffic entering the freeways during peak traffic hours means we can accommodate more vehicles per hour on the freeways, help traffic move at a steadier speed, shorten commute times, and provide a higher degree of safety.
The rate at which vehicles are allowed to enter the freeway at a metered ramp depends on the level of traffic congestion on the freeway, as measured by a sensor located immediately upstream of the ramp. The fastest rate at which vehicles can enter an uncongested freeway at a ramp meter is about 10 vehicles per minute per lane OR 6 seconds per vehicle. The slowest rate during heavy freeway congestion is about 5 vehicles per minute per lane OR 12 seconds per vehicle.
There are nearly 400 freeway on-ramps in the Phoenix metropolitan region. Only about 180 of them have ramp meters at this time. Ramp meters are typically installed as part of the Freeway Management System expansion.
At present (2010) freeway ramp meters cannot be centrally controlled from the Traffic Operations Center. This capability, to be added in 2012, will enable the ramp metering operation to be more responsive traffic local conditions and special events.
Cameras – Video images from cameras provide a real-time view of traffic on Valley freeways. These are the same camera images you often see during TV traffic reports. In fact, you can view snapshots of freeway images at www.az511.com. ADOT monitors these cameras from the ADOT Traffic Operations Center to see how traffic is moving on freeways and identify trouble spots. If an accident happens on the freeway, ADOT operators can assess the scene and provide information to public safety and emergency crews.
Dynamic Message Signs – These electronic overhead signs can display timely and important traffic information such as incidents, upcoming construction and closures, restrictions on freeway lanes, or even
special event venue traffic guidance. ADOT also displays AMBER Alert information on the electronic signs. There are 65 signs in the metro area, with more planned. Technology is just one tool to help maximize our region’s freeway network. HOV lanes, also known as ‘carpool lanes’, are specially designated freeway lanes for use by those vehicles with two or more occupants, buses, and motorcycles. HOV lanes carry more passengers in fewer vehicles than general purpose lanes and help to reduce emissions. HOV lanes are designated by a diamond marking and signage, and are in effect during the morning and late afternoon rush hours.
什么是高速公路管理系统
20世纪90年代中期以来，一直是及其区域高速公路系统的关键组成部分。阿多的高速公路管理系统包括技术和系统，帮助改善交通河谷高速公路，信息流提供约崩溃或建造驾驶者，并帮助阿多和其他机构更好地应对交通事故。
你可以看到它的高速公路上工作的每一天。
一些技术，你看到在地铁区域的高速公路包括：
匝道仪 - 在高速公路入口处这些信号调节合并到高速公路车辆的时机。兰普米运作在早上和下午的上下班时间。有些入口坡道有1米的斜坡信号，有两个人，每个通道之一，即允许交替的车辆进入停机坪。
调节繁忙时间的交通车流进入高速公路意味着我们可以容纳更多的车辆每小时的高速公路上，帮助交通在稳定速度前行，缩短通勤时间，并提供更高的安全程度。
这些车辆在被允许进入一个咪表坡道高速公路率取决于在高速公路上的交通挤塞水平，立即由一个传感器位于上游的坡道衡量。最快的速度在哪些车辆可以进入一米一非拥堵高速公路匝道约10分钟，每线每车车辆或6秒。在拥挤的高速公路重速度最慢的是每线约5分钟车每车或12秒。
有近400名高速公路在凤凰城都会区，坡道。只有约180名已在这个时候坡道米。兰普米，通常安装在高速公路管理系统的扩展部分。
目前（2010年）高速公路匝道不能集中运营中心从交通控制米。这种能力，将在2012年加入，将使匝道的运作，更能当地交通条件和特别活动。
相机 - 从相机提供交通实时查看视频图像上谷高速公路。这是相同的摄像机图像你经常在电视交通报告中看到。事实上，你可以查看www.az511.com高速公路图像快照。阿多显示器从阿多特交通营运中心，看看这些相机正在高速公路上的交通，并找出故障点。如果事故发生在高速公路上，阿多运营商可以在现场评估，并提供信息，公众安全和救援人员。
动态信息标志 - 这些电子架空标志可以显示如事故及时和重要的交通信息，即将建设和封锁，高速公路上行车，甚至限制
特别活动场地的交通指导。阿多也显示在电子标志安珀警报信息。有65个迹象，都会区与更多的计划。技术只是一个工具，以帮助最大限度地提高本地区的高速公路网络。高容量车道，也被称为'以供这些车辆使用两个或更多的占用，公交车和摩托车共乘车道'，是专门指定的高速公路通道。 HOV车道的行车线的车辆减少携带更多的乘客比一般用途线，并有助于减少排放。 HOV车道的行车线指定一个标记和标志钻石，实际上是在早上和傍晚繁忙时间。
