Here are some key features of BRT: 1. **Dedicated Lanes**: BRT systems often use dedicated lanes to minimize delays caused by traffic congestion.

The California Air Resources Board (CARB) is the state agency responsible for regulating air quality in California. It was established in 1967 and operates under the California Environmental Protection Agency (CalEPA). CARB's primary mission is to achieve and maintain healthy air quality for all Californians, which includes reducing air pollution and greenhouse gas emissions.

Carpooling is a transportation arrangement where multiple people share a vehicle to travel together to a common destination or along a similar route. This practice can reduce the number of vehicles on the road, lower transportation costs, decrease travel time, and minimize environmental impact by reducing emissions. Carpooling can happen informally, such as friends or coworkers driving together, or through organized platforms and apps that connect riders and drivers.

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.

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.

"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.

DTU Roadrunners is a running club based at the Technical University of Denmark (DTU). The club typically offers opportunities for students, faculty, and staff to engage in running activities, participate in races, and promote an active lifestyle within the university community. The club may organize regular training sessions, social runs, and events to encourage participation in running as a form of exercise and social interaction.

Indirect land use change (ILUC) refers to the unintended consequences of biofuel production on land use in regions not immediately connected to the biofuel production process. When biofuels are produced, they can lead to changes in land use patterns that may not be directly associated with the initial agricultural activity.

The Eco-Runner Team Delft is a student-led initiative based at Delft University of Technology in the Netherlands. The team focuses on the design, construction, and racing of hydrogen-powered and energy-efficient vehicles. Their primary aim is to promote sustainable transportation and raise awareness about renewable energy technologies. The Eco-Runner Team participates in various competitions, including the Eco-Runner Challenge, where teams from around the world develop vehicles that run on hydrogen fuel cells.

The effects of cars can be examined from various perspectives, including environmental, economic, social, and health-related aspects. Here are some key effects of cars: ### Environmental Effects 1. **Air Pollution**: Cars emit pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), and volatile organic compounds (VOCs), contributing to poor air quality and respiratory issues.

The FIA Foundation for the Automobile and Society is a charity organization associated with the Fédération Internationale de l'Automobile (FIA), which is the governing body for world motor sport and the promoter of international motor sport. Founded in 2001, the FIA Foundation focuses on key issues related to road transport, mobility, and their impact on society. Its mission is to promote sustainable mobility and improve road safety globally.

A volvelle is a type of interactive paper device that consists of one or more rotating wheels or disks, often used in books or other printed materials. The disks are usually attached to a central point, allowing them to spin and reveal different information or images beneath them. Volvelles were historically used for various purposes, including teaching, demonstrating astronomical concepts, calculating dates, and even for entertainment.

Flexicar is a car-sharing service that allows users to rent cars on a flexible, short-term basis. This service is part of the broader trend of car-sharing and mobility services, which provide an alternative to traditional car ownership. Flexicar typically enables users to access a variety of vehicles, from compact cars to larger models, based on their needs at any given time.

Food miles refer to the distance food travels from where it is produced to where it is consumed. This concept is often used to measure the environmental impact of food transportation, as longer distances typically mean higher greenhouse gas emissions due to transportation, whether by truck, plane, or ship. The idea behind food miles is to highlight the carbon footprint associated with transporting food products. It encourages consumers to consider the source of their food and the environmental implications of their food choices.

The Global Alliance for EcoMobility is an international network that promotes sustainable and eco-friendly urban mobility solutions. Launched in 2015, the alliance aims to foster collaboration among city leaders, policymakers, urban planners, and various stakeholders to advance sustainable transportation practices.

Hitchgathering is an event designed for hitchhikers, travelers, and people interested in the hitchhiking community to come together, share stories, and exchange experiences. These gatherings often focus on themes such as adventure, community, and alternative forms of travel. Participants typically engage in various activities, such as storytelling, workshops, and possibly organized rides or group hitchhiking experiences. The goal is to foster connections among those who share a passion for travel and exploration through hitchhiking.

A hydrogen station, also known as a hydrogen refueling station (HRS), is a facility designed to refuel hydrogen-powered vehicles, such as hydrogen fuel cell electric vehicles (FCEVs). These stations serve a vital role in the hydrogen economy by providing the necessary infrastructure for vehicles that use hydrogen as a clean fuel source.

Hypermobility in the context of travel typically refers to the phenomenon where people frequently move between different cities, countries, or regions for work, leisure, or personal reasons. It can encompass various aspects, such as: 1. **Frequent Travel**: Individuals who travel often for business or personal reasons might be referred to as hypermobile.
