TPL stops - Physical stops

Identification and location data of local public transport (TPL) stops. In the context of the Regional Transport Information System (SIRT), the LPT physical stops - understood as punctual infrastructures that allow citizens to use the scheduled service - are related to two other significant geographical entities: the company poles and knots (nodes-stop). In particular. for: PHYSICAL STOP or STOP means the stop point to allow access to the scheduled service is by its nature one-way. The stop has a unique coding on a regional scale. The stop is always associated with a single node-stop. One stop can correspond to one or more company poles (metadata available at https://www.dati.piemonte.it/#/catalogodetail/regpie_ckan_ckan2_yucca_sdp_smartdatanet.it_FermateTplFermateFisiche_26489). A node is a conceptual entity that groups one or more physical stops, generally the two stops that are in opposite directions of the road. It follows that the node has no direction or direction. Each node is identified by a regionally unique numeric code (metadata available at https://www.dati.piemonte.it/#/catalogodetail/regpie_ckan_ckan2_yucca_sdp_smartdatanet.it_FermateTplNodi_25847). COMPANY PALINA or PALINA, means the vertical signage that indicates the passage of a line service carried out by a given company at a specific stop. Each stake is always associated to a single stop and consequently to a single node (metadata available at https://www.dati.piemonte.it/#/catalogodetail/regpie_ckan_ckan2_yucca_sdp_smartdatanet.it_FermateTplPalineAziendali_26581). The datasets describe the individual entities (stops, nodes-stops and company poles) through their own attributes and two additional fields that report the identification codes of the other related entities. For a complete information we suggest the contextual consultation of the three datasets. It is currently possible that a stop has no associated poles or that a node has no associated stops. In addition, some poles may not have a company code associated with them. Work is ongoing to continuously update and improve the quality of the data. Under no circumstances can the Piedmont Region and the Piedmont Mobility Agency be held liable if they are used for purposes other than purely cognitive ones.

本数据集收录本地公共交通（Public Transport, 简称TPL）停靠站点的标识与位置信息。在区域交通信息系统（Regional Transport Information System, 简称SIRT）的语境下，实体公共交通停靠站（LPT Physical Stop，以下简称实体停靠站）指供市民搭乘定时班次服务的定点基础设施。实体停靠站与两类重要地理实体相关联：企业站牌（Company Pole，以下简称站牌）与节点式停靠站（Node-Stop，以下简称节点站）。

具体定义如下：
1. 实体停靠站（或简称停靠站）：指供乘客接入定时班次服务的停靠点位，其属性天然为单向通行。该站点在区域范围内拥有唯一标识码，且始终仅关联一个节点站。一个实体停靠站可对应一个或多个企业站牌，相关元数据可参见：https://www.dati.piemonte.it/#/catalogodetail/regpie_ckan_ckan2_yucca_sdp_smartdatanet.it_FermateTplFermateFisiche_26489。
2. 节点式停靠站（简称节点站）：为聚合一个或多个实体停靠站的概念性实体，通常对应道路双向的两个实体停靠站。因此节点站不具备通行方向属性，其拥有区域唯一的数字编码，相关元数据可参见：https://www.dati.piemonte.it/#/catalogodetail/regpie_ckan_ckan2_yucca_sdp_smartdatanet.it_FermateTplNodi_25847。
3. 企业站牌（或简称站牌）：指用于标识特定运营企业的线路班次在指定停靠站经停的立式标识牌。每个站牌始终仅关联一个实体停靠站，进而关联至一个节点站，相关元数据可参见：https://www.dati.piemonte.it/#/catalogodetail/regpie_ckan_ckan2_yucca_sdp_smartdatanet.it_FermateTplPalineAziendali_26581。

本数据集通过各实体自身属性，以及两个用于标注关联实体标识码的附加字段，对三类实体（实体停靠站、节点站与企业站牌）进行描述。如需获取完整信息，建议同步查阅这三个数据集。

当前存在部分实体无关联对象的情况：例如实体停靠站未关联任何企业站牌，或节点站未关联任何实体停靠站；此外，部分企业站牌可能未绑定企业编码。目前相关方正持续推进数据的更新与质量优化工作。
