Casos de Sucesso Project Name: Brazil Nova Dutra Weigh Stations Client Name: Faixa Sinalização Viaria Limited End User: Concessionária de Rodovia Presidente Dutra S.A. (Nova Dutra) Contract Value: $635,000.00 USD Date of Award: October 1997 Date of Completion: March 2000 Location: Guararema (80 km East of São Paulo); Queluz (250 km East of São Paulo); Both on São Paulo - Río de Janeiro highway (Presidente Dutra BR116). Project Description: IRD has supplied, designed, supervised installation and commissioned two automated Single Load Cell Medium Speed WIM sorting systems, including Slow Speed WIM scale technology for citation issuance in 1999 and 2003. These systems have set the operational standard for future weight enforcement systems in Brazil. The Nova Dutra Weigh Station Systems consist of two weigh stations with selective and precision scales. The precision scales are used for the purposes of weight enforcement. In addition, mainline sensors are installed on the main highway adjacent to each weigh station to detect violators attempting to evade the weigh station. Each Weigh Station System will sort vehicles based on their weight compliance, and assist the operators in selecting vehicles for random safety inspections. If a vehicle is not in violation and is not selected for a random safety inspection, it can proceed through the Weigh Station with a minimum of delay. The vehicle's weights are determined by Weigh-In-Motion technology. The overall station control and operation is provided by "point-and-click" user display screens provided on four Windows NT machines. A video camera is located following the Slow Speed Scale. The image of each vehicle passing over the SSWIM is captured by a Windows NT PC and stored in a file. The file name of the file containing the image is stored in the Oracle Database with the appropriate vehicle record so the vehicle data can be matched with the vehicle image.
