England (Major) Roads Traffic Data

National Traffic Information Service (NTIS) collects traffic data from various sensors and makes them available in isolation or as “fused” services. The processed data is averaged across all lanes of the carriageway and reported on a per network link basis every minute. This is known as the Processed Traffic Data (PTD). Sensor-only data is that which has been collected from sensors on the road including data from MIDAS Gold sites every minute and from TMU and ANPR equipment every 5 minutes. Data such as speed, flows, occupancy, headway and travel times is processed and reported on a per network link basis.

Tables include:
- Traffic Metrics by Event (Traffic Flow, Traffic Concentration, Traffic Headway, Traffic Speed, Travel Time Data for each PTD Network Link/Event)

Fields include:
- Network Link ID
- Datetime of Event/Measurement
- Measurement Type (d2lm:TrafficFlow, d2lm:TrafficConcentration, d2lm:TrafficHeadway, d2lm:TrafficSpeed, d2lm:TravelTimeData)
- Measurement Value

Expected Workflow:
- Apply for this personalised service and Atheon will arrange to turn on your Traffic Data service
- All traffic data will be available immediately through the Snowflake datashare objects
- Any additional NTIS traffic signals that is added, will be made available in the same Snowflake datashare objects

国家交通信息服务（National Traffic Information Service，NTIS）从各类传感器采集交通数据，并可独立输出或以“融合”服务的形式对外提供。经处理的数据会对整条行车道的所有车道取平均值，并以每分钟一次的频率按每个网络链路（network link）为单位上报，该类数据即称为处理后交通数据（Processed Traffic Data，PTD）。纯传感器数据指从道路传感器采集的数据，包括每分钟更新一次的MIDAS Gold站点数据，以及每5分钟更新一次的TMU和ANPR设备数据。速度、流量、占有率、车头时距、行程时间等数据会经过处理后，按每个网络链路为单位进行上报。

原始NTIS Datex II服务的完整详情可访问以下网址获取：https://www.trafficengland.com/resources/cms-docs/user-guide.pdf

数据集包含以下表格：
- 按事件分类的交通指标（针对每个PTD网络链路/事件的交通流量、交通浓度、交通车头时距、交通速度、行程时间数据）

数据字段包括：
- 网络链路ID（Network Link ID）
- 事件/测量日期时间
- 测量类型（d2lm:交通流量、d2lm:交通浓度、d2lm:交通车头时距、d2lm:交通速度、d2lm:行程时间数据）
- 测量值

预期工作流程：
- 申请该个性化服务后，Atheon将为您开通交通数据服务
- 所有交通数据可通过Snowflake数据共享对象立即获取
- 后续新增的所有NTIS交通信号数据，也将通过同一Snowflake数据共享对象对外提供

背景与挑战

背景概述

该数据集由英国国家交通信息服务（NTIS）提供，涵盖英格兰主要道路的实时交通数据，包括速度、流量、占用率等关键指标，每分钟或每5分钟按网络链接报告。数据来自多种传感器，并经过处理融合，适用于交通分析和规划应用。
