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.
BNA Score. A score out of 100 points representing the quality and connectivity of the bike network in a given area (typically a city) generated by the BNA.
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 Ratings. A PeopleForBikes program that measures the quality of bike infrastructure in cities.
City rating. A city’s overall score in the City Ratings program, out of 100 possible points. For U.S. cities, the city rating consists of two inputs: The Community Survey Score, worth 20% of the total, and the Bicycle Network Analysis Score, worth 80% of the total score. For international cities, the city rating may or may not include a Community Survey Score. If not, the city rating is equivalent to the BNA Score.
City Snapshot. A survey fielded by PeopleForBikes in which respondents, typically city transportation staff, provide input to inform the Bicycle Network Analysis and City Ratings, such as local speed limits and initiatives to improve bike infrastructure. The City Snapshot is not scored.
Community Survey. An opinion survey fielded by PeopleForBikes that measures how people feel about bicycling in their city. Anyone can respond for a city that they live in, work in, or frequently visit.
Community Survey Score. An aggregate score for a city out of 100 points based on responses to the Community Survey.
Rank. A city’s numerical place among all cities rated (can be subdivided by country, region, state, population size), e.g. 4 out of 158 small U.S. cities
Scorecard. A specific kind of brochure that summarizes City Ratings 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).

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.
City Rating Entry. A series of values compiled by the city ratings program for a specific city. Each value is a score out of 100 for a category like "employment", or "retail" for instance.
