A mixed space-time and wavenumber domain model for predicting ground vibration from railway tracks
(
National Technical University of Athens
, 2015 , Conference Paper)
In this paper, a mixed model for studying ground vibration generated from surface railway tracks is presented. A ballasted track with nonlinear resilient components is modelled in the time domain using the Finite Element ...
Experimental validation of a numerical model for the ground vibration from trains in tunnels
(
DC/ConfOrg
, 2015 , Conference Paper)
Ground vibration and ground-borne noise from trains in tunnels are attracting increasing attention from researchers and engineers. They are important environmental issues related with the operation of underground networks ...
Modelling the dynamic pile-soil-pile interaction in a multi-layered half-space
(
DC/ConfOrg
, 2015 , Conference Paper)
Within the context of railway ground-borne vibration, the dynamic pile-soil-pile interaction remains an area that has not been sufficiently investigated. Whilst a number of researchers have scrutinised the vibration response ...
Effect of rail unevenness correlation on the prediction of ground-borne vibration from railways
(
DC/ConfOrg
, 2015 , Conference Paper)
This paper presents the influence of rail unevenness correlation on the predicted track and ground vibration. The study is based on an integrated railway model in the wavenumber-frequency domain with varying complexity ...
Quantifying morphology of sands using 3D imaging
(
American Society of Civil Engineers (ASCE)
, 2015 , Article)
Particle morphology plays a significant role in influencing engineering behavior of granular materials. Surface texture, roundness, and sphericity represent distinct multiscale measures needed to fully describe particle ...
Real-Time Dynamic Transit Signal Priority Optimization for Coordinated Traffic Networks Using Genetic Algorithms and Artificial Neural Networks
(
Taylor and Francis Inc.
, 2015 , Article)
Transit signal priority (TSP) has gained popularity in providing public transportation buses with preferential treatment at signalized intersections. Many studies have addressed its implementation in prompting enhanced ...
Fatigue characterisation of full-scale pavements using viscoelastic continuum damage approach for qatar
(
CRC Press/Balkema
, 2015 , Conference Paper)
The population and economy in Qatar have been expanding significantly in the past six years. Accordingly, Qatar is encountering huge development in infrastructure. The existing mix design methods have been developed in the ...
Assessment of linear and nonlinear viscoelastic responses of warm-mix asphalt binders
(
CRC Press/Balkema
, 2015 , Conference Paper)
Warm-Mix Asphalt (WMA) technology is widely used in the paving industry due to its impact on reduction of asphalt mixing and compaction temperatures. Characterisation of WMA in the past had focused on evaluating the linear ...
Mitigation of railway-induced vibration by using subgrade stiffening
(
Elsevier Ltd
, 2015 , Article)
Railway-induced ground vibration is often associated with sites with soft ground. Stiffening of the subgrade beneath the railway track is one particular measure that has potential to reduce the vibration level at such ...
Comparison of SimTraffic and VISSIM Microscopic Traffic Simulation Tools in Modeling Roundabouts
(
Elsevier B.V.
, 2015 , Conference Paper)
Abstract SimTraffic and VISSIM are two microscopic traffic simulation tools that are capable of modeling arterial roads with signalized intersections and roundabouts. This study compares the performance of the two simulation ...
