Main Roads Western Australia and Anditi have revolutionised road safety assessments with an approach that automatically detects road infrastructure data applied on 2,000km of roads across the State. In their goal of Star Rating the safety of 80 per cent of the State’s most travelled roads,
Main Roads WA partnered with iRAP and Anditi to design and develop a more automated, accurate and cost-effective solution for road assessment, to update roadside risk ratings and extract asset management data. The project analysed 2,000kms of urban and rural roads using Anditi’s RoadViewer technology and 3D Web Portal.
The world-first LiDAR-derived iRAP-accredited technology enables the automated extraction and visualisation of road safety attributes and asset data from Mobile LiDAR and 360 Degree Imagery. The technology captured median type and width, roadside objects, centreline rumble strips, intersection types, street lighting, trees, and property access points.
Main Roads WA Project Manager Fritha Argus stated that, in the past, managing road assets meant that surveyors had to drive thousands of kilometres along the roads and record videos while observing roadside features.
She spoke enthusiastically about how their collaboration with iRAP and Anditi enabled them to expedite data accumulation, cut costs, and most significantly, allowed for scalability on their network with ease.
This approach adheres to the criteria of both AusRAP and iRAP Star Rating while reducing data collection costs by more than half. Moreover, it eliminates the need for manual data collection along these roads and thus enhances workplace health and safety.
Main Roads WA are taking steps to reach its road safety objectives, while also managing and accessing its geographic information resources to be able to assess their maintenance needs and ensure they adhere to regulations.
The timing of this project is crucial for Australian road agencies. It aligns perfectly with the National Road Safety Strategy 2021-2030, which intends to halve fatalities and serious injuries per capita. Strengthening the security of infrastructure planning and investment, as well as regional roads, are essential objectives of the Strategy.
This follows in the footsteps of the 2018-2020 National Road Safety Action Plan, which established targets seeking that 90% of trips on national highways and 80% of journeys on state highways meet a 3-star or better safety rating by 2020.
More than 280,000km of Australia's roads have been assessed via AusRAP Star Rating by various transportation organisations and clubs.
iRAP Global Innovation Manager Monica Olyslagers pointed out how the automation of data capture created in this project could bring about the routine large-scale safety Star Rating assessments and Fatality and Serious Injury Estimates to be a fundamental part of the highway asset management process.
She maintained that faster, more economical data collection methods would allow for far-reaching safety audits to be conducted yearly. This information would be beneficial in fostering developments in road safety as well as providing guidance for both state and national decision-making and investments.
An estimated 1,100 to 1,200 people succumb to fatalities from road collisions yearly in Australia. Additionally, 40,000 experienced lasting disabilities due to the incident.
