The majority of the city's residents move about Antananarivo on foot. The CUA sets and enforces rules that govern a system of 2,400 franchised private minibuses running on 82 numbered routes throughout the city. An additional 2,000 minibuses managed by the Ministry of Transportation run along 8 lines into the neighboring suburbs. These interlinked bus systems served around 700,000 passengers each day. These minibuses often fail to meet safety standards or air quality requirements and are typically overcrowded with passengers and their cargo. Police and ''gendarmes'' assist in regulating traffic at peak periods in the morning and evening, or around special events and holidays. Private licensed and unlicensed taxis are common; most vehicles are older Renaults or Citroens. Newer vehicles congregate near hotels and other locales frequented by foreigners willing or able to pay higher prices for better services.
