1. Urban planning restrictions: Dujiakan is located in downtown area, and urban planning restricts road expansion and reconstruction. Therefore, it is impossible to alleviate traffic congestion by directly expanding roads.
2. Incomplete road network: The road network near Dujiakan is relatively imperfect, the road connection is not smooth, and there is no efficient transportation hub, which leads to poor vehicle mobility and increases the possibility of traffic congestion.
3. Increase in car ownership: With the development of social economy and the improvement of people's living standards, more and more families buy cars, which leads to the increasing number of cars on the road and the increasingly serious traffic congestion.
4. Improper traffic management: The traffic management department has shortcomings in road arrangement, traffic signal lamp setting and road planning, which is also one of the reasons leading to traffic congestion.
5. Insufficient public transport facilities: The public transport facilities in Dujiakan area are not enough to meet a large number of travel needs, resulting in some private cars occupying public transport resources and aggravating road congestion.
In a word, the traffic jam in Dujiakan involves many factors. To solve it, we need to take comprehensive measures from urban planning, road network improvement, traffic management, public transport facilities construction and other aspects to effectively alleviate the traffic congestion problem.
