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 (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 (result).
The system (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 (go) up, until now has been a great drop in both. One reason (be) that the shared streets system encourages people to be more (care). Without traffic rules, people slow down and pay more attention each other. Normal traffic systems, on the other hand, depend on signs, 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 (free) when there is a lot of traffic.
