From Microscopic to Macroscopic Traffic Models
نویسنده
چکیده
The paper presents a systematic derivation of macroscopic equations for freeway traffic flow from an Enskog-like kinetic approach. The resulting fluid-dynamic traffic equations for the spatial density, average velocity, and velocity variance of vehicles are compared to equations, which can be obtained from a microscopic force model of individual vehicle motion. Simulation results of the models are confronted with empirical traffic data.

Assessment of macroscopic models of Traffic Flow
The work discussed in this paper consists of a statistical assessment of various finite difference schemes for approximating macroscopic models of traffic flow. Using VISSIM we simulated traffic flow on a section of a freeway with arbitrary characteristics. VISSIM is a traffic flow simulator that uses a microscopic model for traffic. By using data from a microscopic simulation, we are able dete...
متن کاملIntegrated macroscopic traffic flow and emission model based on METANET and VT-micro
We present a framework to integrate macroscopic traffic flow models with microscopic emission and fuel consumption models. Since macroscopic traffic flow models do not provide the acceleration as an output, while microscopic emission and fuel consumption models require both the instantaneous speeds and accelerations as input, we describe how to generate these variables. In particular, we consid...
متن کاملDeveloping a Model of Heterogeneity in Driver’s Behavior
Intelligent Driver Model (IDM) is a well-known microscopic model of traffic flow within the traffic engineering societies. While it is a powerful technique for modeling traffic flows, the Intelligent Driver Model lacks the potential of accommodating the notion of drivers’ heterogeneous behavior whenever they are on roads. Concerning the above mentioned, this paper takes the lane to recognize th...
متن کاملHybrid microscopic-mesoscopic traffic simulation
Traffic simulation is an important tool for modelling the operations of dynamic traffic systems and helps analyse the causes and potential solutions of traffic problems such as congestion and traffic safety. Microscopic simulation models provide a detailed representation of the traffic process, which makes them most suitable for evaluation of complicated traffic facilities and Intelligent Trans...
متن کاملDerivation of non-local macroscopic traffic equations and consistent traffic pressures from microscopic car-following models
This contribution compares several different approaches allowing one to derive macroscopic traffic equation directly from microscopic car-following models. While it is shown that some conventional approaches lead to theoretical problems, it is proposed to use a smooth particle hydrodynamic approach and to avoid gradient expansions. The derivation circumvents approximations and, therefore, demon...
