Road Traffic — Counting Sections — Department of Loiret — 2010

Homogeneous traffic sections on the departmental road network of the Loiret — Edition 2010 **Collection context** Knowledge of the total traffic to be flowed on a road (all vehicles combined) is essential in order to give the track geometric characteristics in relation to its importance and the speeds used, to draw up accident checks and to propose route or safety arrangements. It is also essential to calculate the road structure necessary for rehabilitation or development projects, based on heavy goods traffic. **Collection method** The departmental road network has been divided into homogeneous traffic sections. In addition to permanent stations, temporary counts are carried out by D2I teams each year to complete the road traffic base. Each year, nearly 500 meter installation and deposit have been carried out on a time-by-day basis. In order to consolidate and secure the road traffic base, it was decided to count at least once every 5 years the traffic of each section. The counting frequency is calculated according to predefined criteria. **Attributes** | Champ | Alias | Type | | — | — | | — | | ‘MJA_PL’ | ‘integer’ | | ‘PRCPT’ | ‘char’ | ‘PRCPT’ | ‘SHAPE.LEN’ | ‘double’ | | ‘ABF’ | ‘integer’ | | ‘ABD’ | ‘integer’ | | ‘cumuld’ | ‘integer’ | | ‘PL’ | ‘double’ | | ‘PRDFIN’ | ‘char’ | ‘PRDFIN’ | ‘OBJECTID_1’ | ‘integer’ | | ‘PRD’ | ‘integer’ | | ‘ROUTE’ | ‘char’ | | ‘IDROUTE’ | ‘char’ | ‘IDROUTE’ | | ‘MJA’ | ‘integer’ | | ‘ObjectID’ | ‘integer’ | | ‘PRF’ | ‘integer’ | | ‘CATEGORIA’ | ‘char’ | | ‘CUMULF’ | ‘integer’ | | ‘TYPE’ | ‘char’ | | ‘LIEU’ | ‘char’ | | ‘PRDDEB’ | ‘char’ | ‘PRDDEB’ For more information, see [the metadata on the Isogeo catalog](https://open.isogeo.com/s/1742fb942d7b4756b9778c3b3cbc992e/HWglEr-z4Bry_rKQOTINX9gAH4Yu0/r/c55a8eda49da4230b333f0b70690775f).## 卢瓦雷省（Loiret）省道网均质交通路段——2010版 **采集背景** 掌握道路总交通量（所有车型合计）是开展以下工作的必要前提：依据道路重要性与通行车速确定其几何设计参数、开展事故核查工作、拟定路线优化或安全保障方案；同时，基于重型货运交通量计算道路修复或改扩建工程所需的路面结构参数，同样离不开交通量数据支撑。 **采集方法** 该省道网已被划分为若干均质交通路段。除固定监测站点外，D2I团队每年还会开展临时交通量统计，以完善基础交通数据库。每年完成近500个测点的安装与部署，并按日开展计时统计。为巩固并保障基础交通数据库的可靠性，规定每条路段至少每5年开展一次交通量统计，统计频次依据预设标准确定。 **属性** | 字段名 | 别名 | 数据类型 | | ---- | ---- | ---- | | MJA_PL | 无 | 整型 | | PRCPT | PRCPT | 字符型 | | SHAPE.LEN | 无 | 双精度浮点型 | | ABF | 无 | 整型 | | ABD | 无 | 整型 | | cumuld | 无 | 整型 | | PL | 无 | 双精度浮点型 | | PRDFIN | PRDFIN | 字符型 | | OBJECTID_1 | 无 | 整型 | | PRD | 无 | 整型 | | ROUTE | 无 | 字符型 | | IDROUTE | IDROUTE | 字符型 | | MJA | 无 | 整型 | | ObjectID | 无 | 整型 | | PRF | 无 | 整型 | | CATEGORIA | 无 | 字符型 | | CUMULF | 无 | 整型 | | TYPE | 无 | 字符型 | | LIEU | 无 | 字符型 | | PRDDEB | PRDDEB | 字符型 | 如需了解更多信息，请参阅[Isogeo目录元数据](https://open.isogeo.com/s/1742fb942d7b4756b9778c3b3cbc992e/HWglEr-z4Bry_rKQOTINX9gAH4Yu0/r/c55a8eda49da4230b333f0b70690775f)。
