Road Traffic — Counting Sections — Department of Loiret — 2007
收藏资源简介：
Homogeneous traffic sections on the departmental road network of the Loiret — Edition 2007 **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 | | — | — | | — | | ‘PL’ | ‘char’ | | ‘MJA’ | ‘integer’ | | ‘NUM_OBJ’ | ‘integer’ | | ‘LIEU’ | ‘char’ | | ‘PRDFIN’ | ‘char’ | ‘PRDFIN’ | ‘SHAPE.LEN’ | ‘double’ | | ‘TYPE_DE_PO’ | ‘char’ | | ‘ETI_1’ | ‘char’ | ‘ETI_1’ | ‘ObjectID’ | ‘integer’ | | ‘SECTEURS’ | ‘char’ | | ‘PRDDEB’ | ‘char’ | ‘PRDDEB’ | ‘ETI_2’ | ‘char’ | ‘ETI_2’ | ‘FIN’ | ‘double’ | | ‘DEBUT’ | ‘double’ | | ‘IDROUTE’ | ‘char’ | ‘IDROUTE’ | | ‘DECALAGE’ | ‘double’ | | ‘PR_COMPT’ | ‘char’ | ‘PR_COMPT’ | | ‘SAVE_X’ | ‘double’ | | ‘CATEGORIA’ | ‘char’ | | ‘SAVE_Y’ | ‘double’ | For more information, see [the metadata on the Isogeo catalog](https://open.isogeo.com/s/1742fb942d7b4756b9778c3b3cbc992e/HWglEr-z4Bry_rKQOTINX9gAH4Yu0/r/47a4ccf6752840f19de56ef5801a5dc7).
# 卢瓦雷省（Loiret）干线公路网均质交通路段——2007版 **采集背景** 掌握道路总交通量（所有车型合计）相关数据，是依据道路重要性与通行速度确定其几何设计参数、开展事故核查以及规划线路或安全设施配置的核心前提。同时，基于重型货车交通量计算道路修复或改扩建项目所需的路面结构，同样不可或缺。 **采集方法** 卢瓦雷省干线公路网已被划分为均质交通路段。除固定监测站点外，D2I工作组每年会开展临时交通量统计，以充实道路交通量基础数据集。年度内累计完成近500处测点的单日连续安装与布设作业。为巩固并保障道路交通量基础数据集的可靠性，明确每路段至少每5年开展一次交通量统计，统计频率依据预设判定标准确定。 **数据属性** | 字段名 | 别名 | 数据类型 | | ------ | ---- | -------- | | PL | 无 | 字符型（char） | | MJA | 无 | 整型（integer） | | NUM_OBJ | 无 | 整型（integer） | | LIEU | 无 | 字符型（char） | | PRDFIN | 无 | 字符型（char） | | SHAPE.LEN | 无 | 双精度浮点型（double） | | TYPE_DE_PO | 无 | 字符型（char） | | ETI_1 | 无 | 字符型（char） | | ObjectID | 无 | 整型（integer） | | SECTEURS | 无 | 字符型（char） | | PRDDEB | 无 | 字符型（char） | | ETI_2 | 无 | 字符型（char） | | FIN | 无 | 双精度浮点型（double） | | DEBUT | 无 | 双精度浮点型（double） | | IDROUTE | 无 | 字符型（char） | | DECALAGE | 无 | 双精度浮点型（double） | | PR_COMPT | 无 | 字符型（char） | | SAVE_X | 无 | 双精度浮点型（double） | | CATEGORIA | 无 | 字符型（char） | | SAVE_Y | 无 | 双精度浮点型（double） | 如需获取更多信息，请参阅[Isogeo目录中的元数据](https://open.isogeo.com/s/1742fb942d7b4756b9778c3b3cbc992e/HWglEr-z4Bry_rKQOTINX9gAH4Yu0/r/47a4ccf6752840f19de56ef5801a5dc7)。
