Cycling is a physical activity and mode of transportation that involves riding a bicycle. It can be practiced for various purposes, including recreation, fitness, commuting, and competitive sports. The act of cycling engages various muscle groups and offers numerous health benefits, such as improved cardiovascular fitness, strength, and flexibility. There are different types of cycling: 1. **Recreational Cycling**: Enjoyed as a leisure activity, often in a scenic environment or as part of social gatherings.
Cyclability typically refers to the quality and measure of how conducive a place is for cycling. It encompasses various factors that influence the ease, safety, and enjoyment of biking in a given area. Key components of cyclability include: 1. **Infrastructure**: Availability of bike lanes, bike paths, bike parking, and bike-sharing programs. 2. **Safety**: The degree to which cyclists feel safe from traffic, including measures like traffic calming, signage, and lighting.
"Complete Streets" is a transportation policy and design approach aimed at creating roadways that prioritize all users, including pedestrians, cyclists, motorists, and public transportation riders. The goal is to provide safe and accessible transportation options for everyone, regardless of age or ability. Key features of Complete Streets include: 1. **Multimodal Infrastructure:** Development of infrastructure that accommodates various forms of transportation, such as bike lanes, sidewalks, crosswalks, public transit facilities, and roadways for vehicles.
The Commuter Challenge is an initiative designed to encourage individuals to use sustainable transportation methods, such as walking, biking, carpooling, or public transit, instead of driving alone. Typically organized as a competition or campaign, the challenge aims to raise awareness about the environmental impact of commuting habits, promote healthier lifestyles, and reduce traffic congestion. Participants often log their commutes over a specific period, track their travel modes, and may earn rewards or recognition for their efforts.
Chariot was a transportation company that aimed to provide a commuter shuttle service using a network of shuttles in urban areas. Founded in 2014, the company focused on offering an alternative to traditional public transportation and ride-sharing services, often targeting employees commuting to and from work. Chariot's service operated with a model that allowed riders to reserve seats on shuttles running along fixed routes, with trips typically designed to cater to the needs of commuters.
Certification for Sustainable Transportation typically refers to programs or initiatives that evaluate and recognize transportation systems, vehicles, or practices that adhere to sustainability principles. These certifications aim to promote environmentally friendly practices in the transportation sector, which is a significant contributor to greenhouse gas emissions and other environmental impacts.
A Certificate of Entitlement (COE) is a key component of the vehicle registration system in Singapore. It is essentially a license that allows an individual to own and use a vehicle in Singapore for a specified period, typically ten years. The COE system was introduced to regulate the number of vehicles on the road and manage congestion.
Carsharing is a transportation service that allows multiple users to rent vehicles for short periods of time, typically by the hour or day, rather than owning a car. This service is designed to provide the convenience of vehicle access without the costs and responsibilities associated with car ownership, such as maintenance, insurance, and parking. Key features of carsharing include: 1. **Accessibility**: Users can easily reserve a vehicle through mobile apps or websites.
Carpooling is a transportation arrangement where multiple people share a vehicle to travel together to a common destination or along a similar route.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
