(QUeues And Delays at ROadworks)
QUADRO is a DfT computer program maintained and distributed by TRL. The purpose of the program is to provide a method of assessing the total cost of major road maintenance works. This can include direct costs such as resurfacing and reconstruction but also the cost imposed on road users while the roadworks are being carried out. QUADRO can be used to compare the full costs of alternative maintenance options and to assess the maintenance implications of different options for road improvements.
