Why does the road feel more and more blocked now? There are 790 thousand private cars in Ji'nan.
life daily May 8th news (reporter Yin Baolong) traffic jam, the current has become a hot topic in the province city people, and the basic reason for the traffic jam is that the car is less than the number of cars, the urban planning can not keep up with the growth of the number of cars, then the current number of cars and road resources What is the situation? On the afternoon of 8, the traffic police brigade held a discussion with 25 key enterprises in Lixia District.
by the end of 2011, the number of motor vehicles in Ji'nan had reached more than 130 million vehicles, of which 930 thousand were cars, and among the cars, private cars accounted for 790 thousand, reaching 85%. In the 5 years from 2007 to 2011, vehicle ownership increased from 460 thousand to 930 thousand, with an average annual growth rate of 25%. In the past 5 years, the average annual growth of private cars has reached over 30%.
the growth of motor vehicles is so rapid, but the growth of road resources is relatively lagging behind. According to statistics from relevant departments, the average annual growth of road length is only 3.4% over the past 5 years, and the average annual growth of Road area is only 6.1%. With the development of the city, there is a certain distance between the place of residence and the work unit. The phenomenon of tidal congestion is particularly obvious in the morning and evening.
Lixia District is a busy area in Ji'nan, with relatively concentrated vehicles. Guo Jichun, the captain of the traffic police brigade, said that in the peak period, 15 of the 24 main roads in the lower region reached saturation, 22 sub roads, 17 saturated roads, 42 branches and 20 saturated. Therefore, although the traffic police work overtime, but the contradiction between the number of vehicles and the road resources makes congestion difficult to solve in the short term.
according to the theory of traffic saturation, the ratio of vehicle flow to road design capacity is the saturation coefficient. If it reaches 0.75, it will feel blocked. According to the data provided by the traffic police, even in the flat peak period, the traffic flow per hour at the intersection of ten and Thousand Buddha mountain roads often reaches more than 6000 vehicles, and the saturation is 1.25, and the congestion level can be imagined.
