Problems solved by technology

[0009] However, the above model cannot directly give the traffic congestion conditions, especially when various traffic parameters change, it can directly give the overall description of the traffic congestion problem, which makes it difficult for traffic system researchers to directly use

Abstract

The invention discloses a stability modeling method of a macroscopic traffic flow viscosity model, which is used to solve the technical problem that the existing models are difficult to directly deal with the problem of traffic congestion. The technical solution is to establish a new traffic model on the basis of the existing model to obtain the relationship between traffic congestion and system stability, so as to determine whether there will be traffic congestion or other abnormal phenomena from a macro perspective by using the perspective of global stability , provide a basic basis for traffic control and decision-making, and be directly applied to deal with traffic congestion problems.

Description

technical field [0001] The invention relates to a modeling method, in particular to a stability modeling method of a macro traffic flow viscosity model. Background technique [0002] In recent years, with the great increase in the number of various means of transportation, facilities, roads, and traffic management systems in many countries in the world have been difficult to adapt to this speed of development, especially in large and medium-sized cities with insufficient traffic infrastructure and traffic signal control. Inconsistency, lack of traffic guidance system, confusion of vehicle scheduling and management, awareness of traffic regulations of traffic participants and many other reasons lead to urban traffic congestion, which in turn leads to a series of social and economic problems such as traffic safety and environmental pollution. question. [0003] Because the traffic problem is a complex large-scale system problem, it involves the comprehensive control of urban ...
