this paper introduces a mesh generating algorithm for solving the traffic flow equation as a conservation law equation. the idea behind the new method is to use the characteristic curves and moving non-oscillatory finite volume method. in addition, when characteristic curves intersect, the proposed scheme uses shock speed equation in order to improve computational efficiency. we also compare...

[email protected] I N T H I S E D I T I O N O F I S PA D M I N , I L O O K at the area commonly referred to as “traffic shaping.” Traffic shaping is the process by which network operators manage the somewhat random flow of packets to and from their networks to achieve the desired flow characteristics. Synonyms for “traffic shaping” include “packet shaping,”“bandwidth limiting,”“rate limiting,...

We contribute to an improved understanding of Internet traffic characteristics by measuring and analyzing modern Internet backbone data. We start the thesis with an overview of several important considerations for passive Internet traffic collection on large-scale network links. The lessons learned from a successful measurement project on academic Internet backbone links can serve as guidelines...

Short-term prediction of traffic flow is central to alleviating congestion and controlling the negative impacts of environmental pollution resulting from vehicle emissions on both inter- and intra-urban highways. The strong need to monitor and control congestion time and costs for metropolis in developing countries has therefore motivated the current study. This paper establishes the applicatio...

Background: A road traffic accident is an incident on a way or street open to public traffic, resulting in one or more persons being killed or injured, and involving at least one moving vehicle. The purpose of this study was to present the prevalence and factors associated with road traffic accident in Chuko town , Southern Ethiopia Materials and Method: Community based cross sectional study w...

Neighborhoods within the hierarchy of urban structure are one of the smallest socio-physical building blocks of cities. Traditional neighborhoods of Iranian historic cities benefited from strong social relations which were flourished over the years and were manifested in the neighborhoods centers. In the modern era, the new master plans and the complementary local plans have disintegrated th...

A modified approach to treat traffic flow parameters (flow, density, and speed) has been introduced in this paper. A queuing analysis has been conducted on traffic flow data on Interstate 94 in the Minneapolis–St. Paul metro area. A methodology has been developed to calibrate loop detector count data. Corrected flow data has been subjected to analysis using queuing analysis to compute densities...

Many address lookup methods for an IP router have been recently proposed to improve a packet forwarding capability, but their performance prediction is very limited because of lack of considering actual traffic characteristics. It is necessary to consider actual traffic to predict more realistic performances on routers, specially in case of layers 3 and 4 switches whose performances are more in...

As an important component of intelligent transportation-management systems, accurate traffic-parameter prediction can help traffic-management departments to conduct effective traffic management. Due the nonlinearity, complexity, and dynamism highway-traffic data, traffic-flow is still a challenging issue. Currently, most spatial–temporal traffic-flow-prediction models adopt fixed-structure time...
