The excellent public transport system in Austin provides cheap public buses and vans that cover all neighbourhoods, including downtown and the university campus, for a flat fare. Transfers between buses are free and valid for three hours. Single fares start from $1.25. Taxis are available from hotel taxi stands during the day and by phone at night. Pedicabs can also be found on the streets in the entertainment districts like East and West 6th Street, and the Warehouse District. Multiple local ride-hailing services are available along with larger companies like Uber and Lyft.Driving in Austin can be very confusing, with a lack of clear east-west routes through the city centre and the fact that locals tend to refer to highways by unofficial names. The city centre can become congested at rush hour.
