The start of the school summer holiday season, at the end of June, is the cue for a mass exodus from the city, as many local residents head off on holiday for a week or two or more. As a result, Prague’s traffic is generally lighter in summer, and the Prague Public Transport Company (Dopravní podník hlavního města Prahy) makes the most of this situation to carry out repairs. In addition, it issues a special summer timetable of reduced or temporarily suspended services.
