A Before-After Safety Evaluation of a New Part-time Protected Right-turn Signal Strategy
This presentation reports on a before-after safety evaluation of a new part-time protected right-turn signal strategy at signalised intersections applying Artificial Intelligence (AI)-based video analytics. For this purpose, the permissive right-turn signals at five signalised intersections were converted to part-time protected right-turn signals, in which protected right-turn signals were mainly implemented during off-peak hours. The […]
Risky Business! Inappropriate risk allocation and understanding the civil industries most difficult risks to price
Proper risk allocation is essential for ensuring project viability, sustainability, and long-term success. Inappropriate risk allocation can undermine the success of civil infrastructure projects by increasing costs, causing delays, reducing quality, stifling innovation, and damaging relationships. The Collaborative Project conducted several industry workshops and one of the key themes that has come up is ensuring […]
Digital Engineering Delivering Benefits for the Coomera Connector Stage 1 Central Project
Project Background: The Coomera Connector, extends for 45km between the Logan Motorway and the Pacific Motorway Interchange at Loganholme and Nerang-Broadbeach Road in Nerang. Once delivered, Coomera Connector will cater for regional population and employment growth, relieve pressure on the Pacific Motorway M1 by reducing its use for local trips, and improve safety and travel […]
Collaboration in TIC-CO Construction
Mt Lindesay Highway – Stoney Camp Rd to Chambers Flat Rd Duplication Project The collaborative endeavour undertaken for this project transcended mere construction; it symbolised a collective drive towards shared success fueled by a common vision. Prior to commencement, Senior Management and the Principal’s administration team forged a strong partnership, recognising mutual alignment in desired […]
Positional Aspects of Geotechnical Control Systems
The frequency of natural disasters worldwide has increased over the last century, with theAsian Pacific region experiencing the highest relative number of natural disasters (GlobalNatural Disaster Assessment Report, 2021). An increase in frequency and intensity of naturaldisasters is forecast as a direct effect of climate change (IPCC Climate Change Report, 2023).To allow critical infrastructure to […]
Integrative Decision Support Tool for Flood-Informed Road Infrastructure Investment Prioritisation
The Inland Freight Route Link Flood Study (IFRLFS), conducted by the Department of Transport and Main Roads (TMR) in collaboration with AECOM, HARC, and NineSquared, represents a significant advancement in flood performance planning for road infrastructure. Central to this study is the development of a groundbreaking decision support tool (DST) designed to guide investment decisions […]
CADD Tools – Exploring technology to improve data quality and enrich user experience
There is a state government mandate to reach digital by default by 2032. Digital by default means moving from paper-based data to data in digital format. TMR has committed to this mandate by implementing a range of digital engineering initiatives including Building Information Modelling on major projects. However, to achieve digital by default, TMR needs […]
Computer vision for vulnerable road user detection at traffic signals
Safe and efficient traffic signal operations rely on accurate detection of all road users, including vulnerable road users (VRU). However, conventional inductive loops struggle to detect pedestrians and push bikes as they have no or little amount of metal. To address this challenge, the ITS and Electrical Technology team evaluated computer vision technology in the […]
Autonomous defect logging
RoadTek has been progressively deploying a new technology referred to as “Autonomous Defect Logging” across the state’s Operational areas between August 2023 and March 2024. The technology involves the installation of a mobile phone to the inside of road inspector’s windscreens where continual still images are taken at predetermined frames per second. The images are […]
Spraying behaviour of polymer and crumb rubber modified binders (NACoE project P111)
Bitumen sprayers in Australia are designed to apply a satisfactory transverse distribution of binder across the pavement from a series of nozzles. These sprayers are calibrated annually to assure this transverse distribution is being achieved, and the calibration is often undertaken with an oil at ambient temperatures that mimics the properties of a conventional bitumen […]
