- DOMI Street Closures For GIS Mapping
- Description
- ## Overview This dataset contains all DOMI Street Closure Permit data in the Computronix (CX) system from the date of its adoption (in May 2020) until the present. The data in each record can be used to determine when street closures are occurring, who is requesting these closures, why the closure is being requested, and for mapping the closures themselves. It is updated hourly (as of March 2024). ## Preprocessing/Formatting It is important to distinguish between a permit, a permit's street closure(s), and the roadway segments that are referenced to that closure(s). The CX system identifies a street in segments of roadway. (As an example, the CX system could divide Maple Street into multiple segments.) A single street closure may span multiple segments of a street. The street closure permit refers to all the component line segments. A permit may have multiple streets which are closed. Street closure permits often reference many segments of roadway. The `roadway_id` field is a unique GIS line segment representing the aforementioned segments of road. The `roadway_id` values are assigned internally by the CX system and are unlikely to be known by the permit applicant. A section of roadway may have multiple permits issued over its lifespan. Therefore, a given `roadway_id` value may appear in multiple permits. The field `closure_id` represents a unique ID for each closure, and `permit_id` uniquely identifies each permit. This is in contrast to the aforementioned `roadway_id` field which, again, is a unique ID only for the roadway segments. City teams that use this data requested that each segment of each street closure permit be represented as a unique row in the dataset. Thus, a street closure permit that refers to three segments of roadway would be represented as three rows in the table. Aside from the `roadway_id` field, most other data from that permit pertains equally to those three rows. Thus, the values in most fields of the three records are identical. Each row has the fields `segment_num` and `total_segments` which detail the relationship of each record, and its corresponding permit, according to street segment. The above example produced three records for a single permit. In this case, `total_segments` would equal 3 for each record. Each of those records would have a unique value between 1 and 3. The `geometry` field consists of string values of lat/long coordinates, which can be used to map the street segments. All string text (most fields) were converted to UPPERCASE data. Most of the data are manually entered and often contain non-uniform formatting. While several solutions for cleaning the data exist, text were transformed to UPPERCASE to provide some degree of regularization. Beyond that, it is recommended that the user carefully think through cleaning any unstructured data, as there are many nuances to consider. Future improvements to this ETL pipeline may approach this problem with a more sophisticated technique. ## Known Uses These data are used by DOMI to track the status of street closures (and associated permits). ## Further Documentation and Resources An archived dataset containing historical street closure records (from before May of 2020) for the City of Pittsburgh may be found here: [https://data.wprdc.org/dataset/right-of-way-permits](https://data.wprdc.org/dataset/right-of-way-permits)
