When there are many small and medium-sized vehicles in urban road traffic flow, the driving stability is good, the sight distance condition is good and the accident rate is low; When the proportion of large vehicles is high, the sight distance of small vehicles driving behind will affect the accident. Similarly, due to the large number of buses in urban traffic, the dynamic difference between buses and trucks makes the speed distribution more discrete, which is easy to cause traffic accidents.
In addition, motorcycles are a special part of urban traffic, which always have a negative impact on safe driving. Therefore, it is necessary to reduce traffic accidents caused by unreasonable urban road traffic composition. For example, trucks are prohibited from passing on roads in some cities, bus lanes are reasonably set up on roads in some cities, and motorcycle licenses are reduced.
For example, Beijing restricts the driving time of heavy trucks on the Fourth Ring Road. Some roads have bus lanes, and fines for occupying bus lanes have been included in the traffic law. Special vehicles drive on the road to reduce bumps.
However, I remember going to Hangzhou because some things were not handled well. I walked on the road to catch up with my working hours. Motorcycles and electric cars, in particular, are very fast and feel like walking on the sidewalk. I am particularly anxious, afraid of being scratched by them. Fortunately, there was an expressway at that time, so it was easy to have serious traffic accidents.
