Dr Charles Karl

Network Operations | ADVI

Dr Charles Karl leads the Network Operations, Freight and Heavy Vehicles teams with the Australian Road Research Board (ARRB). In addition, Charles is the co-technical lead for the Australian Driverless Vehicles Initiative (ADVI). Some current areas of research and development which Charles is directly involved with include: congestion, ITS assets, safety, road user charging, compliance and enforcement, urban freight, freight data, autonomous vehicles, field testing, trials and pilots.

Charles's doctoral thesis in 2003 investigated the response of drivers to a dynamic traveller information system which he had co-developed through a business he founded earlier. In 1999, Charles co-founded Custom Traffic Pty Ltd, which developed a traveller information system based around an aggregation engine that fuses traffic data from traffic control systems such as SCATS, into speeds and travel times for each link and movement on the road network. This information is supplied to travel information service providers such as Intelematics Australia and utilised in products such as the SUNA traffic information and on Google maps.

Dr Tim Martin

Performance Modelling | Asset Management

Dr Tim Martin has graduate and post graduate qualifications in Civil Engineering and a PhD in predicting network-level pavement deterioration from Monash University. Before joining Australian Road Research Board (ARRB) in 1990, Tim spent some 17 years in the investigation, planning, design, contract management and economic evaluation of major Australian and international engineering projects that included bridges, dams, river diversions and open cut mining works.

Tim's research at ARRB has involved leading a road track cost attribution study that underpins heavy vehicle charging. Tim designed and implemented a major observational study using long-term pavement performance (LTPP) and long-term pavement maintenance (LTPPM) sites, experimental studies with accelerated load testing, resulting in the development of pavement deterioration and works effects models for arterial roads. These models are in-pavement life-cycle costing analyses and the estimation of marginal road wear costs. This research extended to the development of deterioration models for unsealed and sealed local roads as part of a national study across all Australian states and the assessment of levels of service for heavy vehicles.
