阅读下面的短文并用英语回答问题,然后将答案写到答题卡相应的位置上(请注意问题后的字数要求)。

[1] Nowadays the cost of a new car has fallen in real terms so that it is cheaper than ever to own one, and better road conditions have also attracted more drivers. The result is overcrowding on the road system, which is one of the problems the local governments are faced with.

[2] When people travel to other towns, the problem might be relieved by getting them to park outside the town. Buses could be provided to take them into the centre. These Park and Ride projects are increasingly popular in the UK. At Southerton, for example, a council-funded project led to a 15% drop in city centre traffic over five months.

[3] What the council found, though, was that the project proved somewhat unpopular with shop owners in the area outside the centre. Many of their shops relied on passing car drivers for some of their trade. As the number of people driving past dropped, so did their incomes.

[4] Making car driving expensive is another way of ____________. Road taxes tend to mean that people use their cars less. Fining drivers who are in areas where cars have been banned can also tend to encourage them to leave their cars behind.

[5] However, one thing has to be got right for any solution to succeed. If we expect people to give up the habit of driving, we must give them an alternative they can rely on. Constant delays, unannounced changes to the timetable and sudden cancellations all discourage people from using public transport. People will only see it as a real choice if the buses and trains are on time.
