The given bar chart provides data about the count of car trips into the city centre made by locals and non-locals from 1996 to 2005. The units are given in thousands.
Overall, journeys by car were more trendy among residents before parking meters were inserted into the downtown. However, after including it, the travels by citizens dramatically dropped, although movements conducted by visitors remained steady; when streets were closed both of them fell in numbers.
According to the diagram, in the beginning, the difference between commuters and outsiders was approximately 5000, 10000 and 5000 respectively. Inhabitants’ trip remained close to this level until 1999, after which it decreased sharply, reaching nearly 4000 in 2002. By contrast, tourists’ campaigns rose from 5000 in 1996 to under 8000 in 1999.
Two major policies stayed roughly constant over the period, between 2000 and 2002. When two streets were closed to traffic – from 8000 to 3000 for locals and 5000 to 4000 for visitors – leaving both groups at similarly low levels by the end of the given period.
