Adaptive Numerical Simulation of Traffic Flow Density.dvi

In this paper, we describe a one-dimensional adaptive moving mesh method and apply it to two traffic flow models introduced in 2009 by Kurganov and Polizzi. These models can be written as a scalar conservation law with a global flux. The proposed schemes are extension of the moving non-oscillatory central schemes, which belong to a class of moving finite volume methods. We also modify the model...

Numerical Simulation of a Mathematical Traffic Flow Model Based on a Nonlinear Velocity-density Function

A mathematical macroscopic traffic flow model known as Lighthill, Whitham and Richards (LWR) model appended with a closure nonlinear velocity-density relationship yielding a quasilinear first order (hyperbolic) partial differential equation as an initial boundary value problem (IBVP) was considered. The traffic model IBVP by finite difference method which leads to a first order explicit upwind ...

Numerical Simulation of Drift-Diffusion Traffic Flow Model

In this study, we present a numerical scheme to solve the drift-diffusion traffic flow model under the steady state. The drift-diffusion traffic flow model consists of a continuity equation and a nonlinear Poisson equation. The continuity equation describes the propagation of density along the road, and the Poisson equation describes the interaction among vehicles. The system equations cannot b...

the effect of traffic density on the accident externality from driving the case study of tehran

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
