City service is mostly provided by four local transportation companies: Unión de Camioneros de Yucatán (UCY), Alianza de Camioneros de Yucatán (ACY), Rápidos de Mérida, and Minis 2000. Bus transportation is at the same level or better than that of bigger cities like Guadalajara or Mexico City. Climate-controlled buses and micro-buses (smaller in size) are not uncommon.
The main bus terminal (CAME) offers first-class (ADO) and luxury services (ADO PLATINO, ADO GL) to most southern Mexico cities outside Yucatán with a fleet consisting of Mercedes Benz and Volvo buses. Shorter intrastate routes are serviced by many smaller terminals around the city, mainly in downtown.
Several groups and unions offer Taxi transportation: Frente Único de los Trabajadores del Volante (FUTV) (white taxis), Unión de Taxistas Independientes (UTI), and Radiotaxímetros de Yucatán, among others. Some of them offer metered service, but most work based on a flat rate depending on destination. Competition has made it of more common use than it was years ago.
Taxis can be either found at one of many predefined places around the city (Taxi de Sitio), waved off along the way or called in by Radio.
Unlike the sophisticated RF counterparts in the US, a Civil Band radio is used and is equally effective. Usually a taxi will respond and arrive within 5 minutes.
Another type of Taxi service is called "Colectivo". Colectivo taxis work like small buses on a predefined route and for a small fare. Usually accommodating 8 to 10 people.
Uber also offers services in Mérida.
Mérida, Yucatán is twinned with 13 cities:
