ok then my second explanation is correct. so let's say the tollway removes the 24 sets of traffic lights and there is no longer a use for them.
as i am sure we can both agree, the tollway will make the roads more efficient for all users/cars.
A: more cars can access the tollway and use it due to the lack of congestion originally caused by traffic = more noise pollution since there will be an increased number of cars going through each day.
B: since the tollway has removed the traffic lights, what we will see is a higher level of traffic and congestion on streets beyond the tollway. think about it like this, if there are a bunch of cars on the tollway and they move onto 'local streets' (where traffic lights still exist), it will cause cars to backup on local streets and lead to more traffic.
D: tollway has replaced traffic lights = less congestion, less traffic because there is no more stop and start of cars (which happens with traffic lights). therefore travel times for users of the tollway decreases.
C is the only one left and i can explain again if necesary
