Traffic jams (堵塞) are a common problem in larger cities. In some cities, traffic jams get so bad during rush hour that it is sometimes   【小题1】 (fast) to walk than to drive. Traffic accidents are also a problem. Sadly these problems are not easy to solve. However, a traffic system (系统) being tested in several cities in Northern Europe has led to some surprising 【小题2】 (result).

The system 【小题3】 (call) “shared streets”. It is a system that has very few traffic laws. As a result, shared street areas have no traffic lights or street signs. Although most people would expect this to cause the number of traffic jams and accidents 【小题4】 (go) up, until now 【小题5】 has been a great drop in both. One reason 【小题6】 (be) that the shared streets system encourages people to be more 【小题7】 (care). Without traffic rules, people slow down and pay more attention   【小题8】 each other. Normal traffic systems, on the other hand, depend on signs, 【小题9】 people often miss or don't follow, leading to accidents. Also, the shared streets system decreases (减少) traffic jams because without fixed (固定的) parking spaces, it is easier for cars to move around   【小题10】 (free) when there is a lot of traffic.
