Traffic Flow on a Road Network
This paper is concerned with a fluidodynamic model for traffic flow. More precisely, we consider a single conservation law, deduced from conservation of the number of cars, defined on a road network that is a collection of roads with junctions. The evolution problem is underdetermined at junctions, hence we choose to have some fixed rules for the distribution of traffic plus an optimization cri...
متن کاملRoad Network Optimization for Increasing Traffic Flow
In the traffic flow on the city road network, it is observed that a new additional road, which is constructed for overcoming the traffic jam, causes more terrible traffic jam. This is well known as Braess’s paradox. Recently, it is pointed out that Braess’s paradox depends on the traffic density and the paradox disappears at high traffic density. The aim of this study is to describe the algorit...
متن کاملTraffic Flow Modelling on the Road Network in the Cities
Original scientific paper Planning of road transport infrastructure is a complex process. One of the major issues is determining the design elements of road infrastructure (road type and number of traffic lanes, cross-sectional profile, etc.). When designing roads, parameters from the international literature are used, containing values derived empirically from local data on traffic flow (mostl...
متن کاملTraffic Flow on Road Junctions
The paper deals with a mathematical model for fluid dynamic flows on road networks which is based on conservation laws. This nonlinear framework is based on the conservation of cars. We focus on traffic circle, which is a finite number of roads that meet at some junctions. The traffic circle with junctions having either one incoming and two outgoing or two incoming and one outgoing roads. We de...
متن کاملTraffic Flow on a Freeway Network
Traffic congestion is an unpleasant fact of modern life. Although difficult to quantify precisely, congestion must cost Californians millions of dollars per day. Since further extensive construction of freeways is unlikely, information technology is being increasingly looked to for amelioration by providing information allowing more efficient use of existing freeways. Statistics plays a major r...
