Multi-lane hybrid traffic flow model: a theory on the impacts of lane-changing maneuvers
This paper introduces a multi-lane hybrid theory that treats lane-changing as temporary blockages, because this is what is physically observed in reality. For maximum accuracy lanechanging vehicles are modeled as discrete particles endowed with limited acceleration capabilities that interact realistically with the multi-lane continuum stream. This discrete-continuum (hybrid) setup is parsimonio...
متن کاملDynamics of the Multi-Depot Pickup and Delivery Problem
This contribution gives an introduction to an integrated vehicle routing and resource allocation problem. We refer to it as the Swap Trailer Problem and formulate the mathematical model. After the analysis of dynamic decision problems and the development of a framework for this problem, we highlight the dynamic aspect of the problem. Two different solution strategies are supposed. Special prope...
متن کاملImpacts of Snowy Weather Conditions on Expressway Traffic Flow Characteristics
Snowy weather will significantly degrade expressway operations, reduce service levels, and increase driving difficulty. Furthermore, the impact of snow varies in different types of roads, diverse cities, and snow densities due to different driving behavior. Traffic flow parameters are essential to decide what should be appropriate for weather-related traffic management and control strategies. T...
متن کاملthe 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...
15 صفحه اولDynamic pickup and delivery problems
In the last decade, there has been an increasing body of research in dynamic vehicle routing problems. This article surveys the subclass of those problems called dynamic pickup and delivery problems, in which objects or people have to be collected and delivered in real time. It discusses some general issues as well as solution strategies.
