解读HERE Maps实时路况标签 [英] Interpreting HERE Maps real-time traffic tags

问题描述

我已经阅读了所有HERE Maps API文档，但找不到答案.这里的实时流量REST API输出中的XML标签是什么意思?

I've read all the HERE Maps API documentation but couldn't find the answer. What is the meaning of the XML tags in the HERE real-time traffic REST API output?

<FI><TMC PC="4375" DE="Rivonia Road" QD="-" LE="0.55047"/><CF CN="0.83" FF="24.0" JF="6.8228" SP="10.78" SU="10.78" TY="TR"/></FI>

有人知道如何解释此输出(我在请求中使用了接近参数)吗?

Does anyone know how to interpret this output (I used proximity parameter in my request)?

推荐答案

我注意到很多人都有这个问题，答案很难找到.我已经在下面发布了标签含义的列表.

I noticed that a lot of people have this question and the answer is somewhat difficult to find. I've posted a list of the tag meanings I could find below.

• "RWS"-道路(RW)项目列表
• "RW" =这是用于在整个道路上流动的复合项. 每个具有交通流量的道路都将出现一个道路项目 可用信息
• "FIS" =流项目(FI)元素的列表
• "FI" =单个流程项目
• "TMC" = TMC位置的有序集合
• "PC" =点TMC位置代码
• "DE" =道路的文字描述
• "QD" =排队方向. "+"或-".请注意，这与 完全合格ID中的行进方向，例如用于 位置107 + 03021，QD为'-'
• "LE" =路段的长度.单位在 文件头
• "CF" =电流.此元素包含有关速度和速度的详细信息 给定流项目的卡纸因子信息.
• "CN" =置信度，指示如何确定速度. -1.0道路封闭. 1.0 = 100％0.7-100％历史值通常介于.7和1.0之间的值
• "FF" =在这条道路上的自由流动速度.
• "JF" = 0.0到10.0之间的数字，表示预期的 旅行质量.封路时，堵塞因素"将 是10.随着数字接近10.0，旅行质量正在提高 更差. -1.0表示无法计算出堵塞因子
• "SP" =速度(基于UNITS)受速度限制的限制
• "SU" =不受速度限制限制的速度(基于UNITS)
• "TY" =给定位置引用"容器的类型信息. 这可以是自由定义的字符串

• "RWS" - A list of Roadway (RW) items
• "RW" = This is the composite item for flow across an entire roadway. A roadway item will be present for each roadway with traffic flow information available
• "FIS" = A list of Flow Item (FI) elements
• "FI" = A single flow item
• "TMC" = An ordered collection of TMC locations
• "PC" = Point TMC Location Code
• "DE" = Text description of the road
• "QD" = Queuing direction. '+' or '-'. Note this is the opposite of the travel direction in the fully qualified ID, For example for location 107+03021 the QD would be '-'
• "LE" = Length of the stretch of road. The units are defined in the file header
• "CF" = Current Flow. This element contains details about speed and Jam Factor information for the given flow item.
• "CN" = Confidence, an indication of how the speed was determined. -1.0 road closed. 1.0=100% 0.7-100% Historical Usually a value between .7 and 1.0
• "FF" = The free flow speed on this stretch of road.
• "JF" = The number between 0.0 and 10.0 indicating the expected quality of travel. When there is a road closure, the Jam Factor will be 10. As the number approaches 10.0 the quality of travel is getting worse. -1.0 indicates that a Jam Factor could not be calculated
• "SP" = Speed (based on UNITS) capped by speed limit
• "SU" = Speed (based on UNITS) not capped by speed limit
• "TY" = Type information for the given Location Referencing container. This may be freely defined string
