EFFECTS OF PAVEMENT SURFACE DEFORMATIONS ON TRAFFIC FLOW

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Effects of Studded Tires on Pavement Wear and Traffic Safety

IN T R O D U C T IO N The question of whether the use of metal studs in automobile tires should be permitted as an aid to winter driving has been a highly controversial issue in Minnesota for a number of years. The state leg­ islature in biennial sessions had legalized their use on Minnesota roads and streets for six successive winters from October 1965 through May 1971. But during its last ses...

Effects of Asphalt Pavement Conditions on Traffic Accidents in Tennessee Utilizing Pavement Management System (PMS)

Intelligent Pavement for Traffic Flow Detection – Phase II

This project is the extension of a Northland Advanced Transportation System Research Laboratory (NATSRL) FY09 project, titled as " Intelligent Pavement for Traffic Flow Detection " , which aims to explore a new approach in detecting vehicles on a roadway by making a roadway section as a traffic flow detector. Sections of a given roadway are paved with carbon-nanotube (CNT) enhanced pavement; th...

Intelligent Pavement for Traffic Flow Detection – Phase I

This project explored a new approach in detecting vehicles on a roadway by making a roadway section itself a traffic flow detector. Sections of a given roadway are paved with carbon-nanotube (CNT)/cement composites; the piezoresitive property of carbon nanotubes enables the composite to detect the traffic flow. Meanwhile, CNTs can also work as the reinforcement elements to improve the strength ...
