Campaign wants people to use their cars less and to walk or cycle more.
Dublin Transport Office wants people to get out of their cars and walk or cycle to school and work.
With the schools closed for the summer, commuters in most cities are enjoying temporary relief from the traffic gridlock.
Under 5 per cent of commuters in Dublin use their bike to get about the city.
Results of a survey of 35,000 students in the Dublin region show that the numbers being brought to school by car has doubled since 1997. The Dublin Transport Office is hoping to reverse this trend.
The number of cyclists in Dublin is very low in comparison to other cities. In cities like Amsterdam up to half the population cycles.
David Maher of the Dublin Cycling Campaign says that the problem is that people are too attached to their cars. There is a lack of road space designated specifically for cyclists.
In the year 2000, 415 people were killed on Irish roads and 10 of these people were cyclists. This is a significant drop since 1991 when 40 cyclists were killed on the roads but safety is still a big issue.
Helen Fallon of the Dublin Transport Office points out that safety levels vary depending on where you live. She says that they are encouraging people who live in residential areas where traffic speeds are low to get on their bikes.
By 2016, the Dublin Transport Office wants to see one in three short journeys made by bicycle.
The Dublin Cycling Campaign believe that the targets set by the Dublin Transport Office are unrealistic and are not backed up by the supporting budget and investment required to ensure road safety.
One of the main problems facing cyclists is competing for space on the roads. Cycle lanes often just disappear. Cars drive on cycle lanes especially in rush hour and you've to watch out for car doors opening out on to the street.
