I disagree with congestion zones mainly because it causes more pollution from public transport such as the tube, busses and taxis. Therefore I disagree with the original question. I personally think that in years there would be less pollution because more people would have eco-friendly cars which would help. From my previous research there have been advantages of a congestion zone and are that it limits traffic and helps cut down pollutants being admitted into the air and cost that is paid helps go towards more environmentally friendly transport. The disadvantages of a congestion zone are that the public have to pay just to go to work or enter the city center. Another disadvantage is that the public resort to using different routs which could result in more congestion zones. I like the fact that the money being paid from a congestion zone goes towards environmentally friendly transport but I strongly disagree that the public have to pay just to travel to work. I think in my over all conclusion I disagree with congestion zones and would be easier if they were removed.
When I looked at the graph about the amount of pollutants outside the nitrogen is decreasing over time. As for sulpher dioxide and benzene they are also decreasing but they are much lower than the amount of nitrogen, I think this shows that there are less cars out of the zone because the numbers are decreasing, this could be because of congestion charges. Then journey times are shortened due to less cars being present. I don’t think nitrogen fits well in the graph because it starts off at a high amount of gas even though I don’t think it would make much difference. I think the data is very accurate because it comes from a reliable source plus a website to prove that. The site from the government makes you know the information is correct. I think the data is accurate and could be tested again (repeat test) but scientifically it wouldn’t need to.
