( American Society of Civil Engineers (ASCE) , 2018 , Conference)In presence of financial constraints and dire need for inspecting deteriorated sewer pipelines, inspection prioritization tools are required. This paper presents a defect based risk assessment model for prioritizing ... -
Evaluation of traffic noise in the state of qatar
( CRC Press/Balkema , 2018 , Conference)Mitigating traffic noise is a major concern for transportation departments worldwide. A number of noise mitigation procedures are recognized to control noise emitting from traffic stream. However, noise reduction potential ... -
The dynamic interaction effects of railway tunnels: Crossrail and the Grand Central Recording Studios
( SAGE Publications Ltd , 2018 , Article)In cities around the world, underground railways offer an environmentally friendly solution to society's increasing demand for mass transport. However, they are often constructed close to sensitive buildings, where the ... -
Evaluation of Transit Signal Priority Implementation for Bus Transit along a Major Arterial Using Microsimulation
( Elsevier B.V. , 2018 , Conference)Transit Signal Priority (TSP) provides preferential treatment for public transit vehicles at signalized intersections when implemented. TSP is usually provided by interrupting the typical signal timings and extending the ... -
In-service video-vibration monitoring for identification of walking patterns in an office floor
( International Institute of Acoustics and Vibration, IIAV , 2018 , Conference)Footfall-induced vibrations in office floors can create significant problems for the occupants and facility owners. Such vibrations cannot be modeled by traditional load models since the vibration response of a floor depends ... -
Determining relative weights of sewer pipelines' components and defects
( American Society of Civil Engineers (ASCE) , 2018 , Article)Condition assessment models for sewer network components can be considered a tool for key personnel to make informed decisions regarding the required interventions on the basis of the current conditions of these components. ... -
