Glossary
In the BNA Mechanics world, there are a lot of concepts which use a lot of words, some times even different ones to say the same thing. The goal of this glossary is to reduce the confusion and improve the clarity of the vocabulary used in the different projects.
Bicycle Network Analysis (BNA). Software that analyzes the quality and connectivity of bike infrastructure in cities.
City Ratings. A PeopleForBikes program that ranks cities annually based on their ratings generated by the BNA.
BNA Analysis. A set of actions that is used to produce a Rating for a single city.
Submission: A quadruplet consisting of a city name, state, country, and FIPS code, provided to initiate an analysis in the BNA. A Submission can have three approval statuses: Pending, Approved, or Rejected.
Pipeline: A set of actions being executed automatically in a specific order.
BNA Pipeline: Pipeline used to collect all the required input data to run a BNA Analysis.
BNA Output. The set of files and data generated by the BNA Analysis for a single city.
Rating. All input, output, and ancillary values associated with running the BNA once for a city. One line in the historical data file represents a rating.
BNA Component. A subsection of the Rating generated by the BNA. There are eight components of a Rating: Summary, Core Services, Infrastructure, Opportunity, People, Recreation, Retail, and Transit.
Rank. A city’s numerical place among all cities rated in a given year based on overall scores (can be subdivided by country, region, state, population size), e.g. 4 out of 158 small U.S. cities.
BNA Mechanics. Open-source working group, including volunteers.
Brochure. A visual document that can be distributed as an image (usually PNG or SVG file), a PDF file or a print.
City Snapshot. A feedback form on the City Ratings website that enables people to provide input to inform the future analyses for their city, such as local speed limits.
Scorecard. A specific kind of brochure that summarizes Rating data for each rated city.
SPRINT. Acronym summarizing the main factors that impact the BNA Score.
- Safe Speeds
- Protected Bike Lanes
- Reallocated Space
- Intersection Treatments
- Network Connections
- Trusted Data
Infrastructure. Refers to any facility that is built to allow people to move around using a bike or other micromobility device that typically travels under 20 mph (32 km/h).
Pipeline: A set of actions being executed automatically in a specific order.
BNA pipeline: Pipeline used to collect all the required input data to run a BNA analysis.

WARNING: the terms bellow are still waiting to be defined properly. They may or may not be included in the glossary.
Shortcode. A 2 to 4 letter code used in CSV file headers to simplify their inclusion in templates during a data-merge operation, typically using SVGGloo. The associated values may be rounded to be integers instead of decimals.
ShortCityRatings. A version of the city ratings where the headers are shortcodes and the values are rounded to be integers instead of decimals.
Shortscorecard. A scorecard with the shortened headers and rounded integer values.
Template. A file, typically an SVG file but it could be any text-based file format, whose goal is to be combined with a shortcode CSV file during a data-merge operation.
