A taxi service provides transportation for passengers in vehicles that can be hailed on the street or booked in advance. Taxis are typically driven by licensed drivers and can accommodate one or more passengers, depending on the vehicle size. The fare is usually calculated based on distance traveled and time taken, with meters installed in the taxi to ensure accurate billing. Taxi services are commonly found in urban areas, where they offer a convenient alternative to public transportation. Many cities have established regulations to ensure safety and reliability, and some taxi companies also offer ride-sharing options through mobile apps, making it easier for passengers to request a ride from their location.
