In the context of network capacity planning and management, traffic matrix (TM) estimation plays a crucial role, as it provides the means for computing the volume of traffic that flows between all pairs of nodes in a network. Since the TM estimation problem was first addressed in [13], various techniques for its solution have been introduced based on observed traffic counts on every link in the...

Estimation of the origin-destination trip demand matrix (O-D) plays a key role in travel analysis and transportation planning and operations. Many researchers have developed different O-D matrix estimation methods using traffic counts, which allow simple data collection as opposed to the costly traditional direct estimation methods based on home and roadside interviews. In this paper, a new fuz...

road transport is a ubiquitous source of lead contamination in the soil near highways with direct and indirect impacts on human health. accumulation of traffic-induced lead in the soils depends on gasoline lead content, traffic volume, as well as meteorological conditions. to evaluate the effect of traffic on soil lead concentration, 113 samples from the topsoil (0-15 cm) were collected in a re...

Pavement rehabilitation could affect the accident severity index (ASI) since restoration measures means more safety for road users. No research or project has been carried out to identify hazard points to build a linear model based on crash severity index. One of the very popular accident severity index models used in all countries is based on linear models to rehabilitate pavements and this pa...

As availability and reliability of observed traffic data significantly affect the accuracy of traffic state estimation, traffic data from probe vehicle technique, which has a potential of network coverage, might be useful to improve the traffic state estimation. The applications of probe vehicle data are still limited as they mostly concentrated on travel time detection, such as in Chen, while ...

OVERVIEW: Traffic control systems for automobile traffic are being set up that allow more advanced traffic signal control according to traffic conditions and provide drivers with the real-time traffic information that they need to make their own driving decisions. The traffic information required by the driver includes traffic regulations, degree of congestion, parking space availability and so...

background: cardiac output (co) is the total volume of blood pumped by the heart per minute and is a function of heart rate and stroke volume. co is one of the most important parameters for monitoring cardiac function, estimating global oxygen delivery and understanding the causes of high blood pressure. hence, measuring co has always been a matter of interest to researchers and clinicians. sev...
