Project Title

Experimental and Numerical Characterisation of Low-Cost Roadside Barrier Solutions

From

02-2011

08-2013

Summary

The NRA is seeking low-cost roadside barrier solutions for National Secondary Roads suitable for implementation following road realignment projects. The current project proposes to use well-established computational modelling techniques to evaluate the potential for proposed new designs that are based on freely available low-cost natural building materials (e.g. stone wall, earth etc.) and which meet cost, aesthetic and engineering requirements. The proposed designs will simultaneously be evaluated for aesthetics and lifecycle cost and a cost/benefit analysis on the proposed designs will be performed by comparison with existing products. A scaled prototype of the final proposed design will be produced and physically crash tested to predict the likely performance of the proposed new design in a full-scale barrier test. If the scaled prototype physical test indicates a high potential for success, a full-scale barrier test will be performed at TRL in the UK.

Project Title

Testing, modelling and optimal design of noise barriers for Ireland

From

10-2010

10-2012

Summary

Noise barriers must satisfy a number of standards with regards to their acoustic performance in a laboratory environment along with their mechanical performance and general safety requirements. However these test methods are not developed with a view to on-site testing or to determine continued performance of barriers. The proposed project aims to improve current assessment procedures for determining the acoustic performance of road traffic noise reducing devices. This will initially involve an assessment of the current European standard method for determining values for sound reflection and airborne sound insulation for a noise barrier using an in-situ technique. An alternative, relatively cheap and rapid technique for measuring the in-situ performance of noise barriers will then be developed.

Project Title

ROTHAR: Route planning and network modelling for cyclists

From

10-2010

10-2014

Summary

In a road network, cyclists are the group exposed to the maximum amount of risk. Route choice of a cyclist is often based on level of expertise, perceived or actual road risks, personal decisions, weather conditions and a number of other factors. Consequently, cycling tends to be the only significant travel mode where optimised route choice is not based on least-path or least-time. The project will involve collecting a significant amount of data using Smart Phones from selectively chosen volunteer cyclists in Dublin representing a wide cross-section of the entire gamut of cyclists. A repository will be established for the cycling routes and other variables for anonymous but uniquely identified cyclists. Interrelationships and clustering for targeted sub-groups within cyclists will be explored from this data. The research will eventually develop a cycling network map of the city with all possible routes marked and indexed according to their safety, reliability, travel time, energy requirement and other attributes. This map would provide an invaluable tool to cyclists in terms of journey safety and time efficiency. CLARITY has funded 5000 for development of a smart-phone based app.

Project Title

Short-term modelling of traffic variable

From

10-2008

10-2012

Summary

Short-term Traffic Flow Forecasting (STFF), the process of predicting future traffic conditions based on historical and real-time observations is an essential aspect of Intelligent Transportation Systems (ITS). This project aims at developing univariate and multivariate STTF algorithms using time-series and neural network algorithms. VARMA model, Structural time-series models, adaptive MLF & RBF models are used to develop new and efficient prediction algorithms using SCATS and MIDAS data. Along with this, vehicular air-pollution levels are also modelled and predicted.

Project Title

Automatic Detection of Damage using Image based Techniques in Underwater Marine Structures

From

10-2011

10-2014

Summary

This project proposes to automate damage detection in underwater marine structures using image based techniques. Access to underwater structures is usually limited and an automated detection can potentially very significantly improve the condition monitoring, operational complexity and financial implications related to deterioration of the structures. The project will develop image based techniques particularly suited to underwater conditions and automatically detect damage and related features of interest. Advanced image segmentation and texture analysis techniques will be significantly employed in this project. Isolation of diverse surface features like marine growth, dusty regions and presence of marine life will be established. Additionally, this image based Non-Destructive (ND) approach will explore the appropriateness and limitations of resurrecting archived image and video data of underwater inspections.
