A highly sophisticated modelling tool is now being offered by PTV. Called the PTV OPTIMA, this modelling tool is said to allow planners to develop an accurate picture of traffic flow.
The package receives data on traffic volumes and speed using detectors and signal control systems. This is then analysed and presented to personnel in a format that is claimed to be easy to understand. Should an accident occur, the system will determine the effect on traffic flow in real-time and will also assess an array of solutions simultaneously.
The PTV OPTIMA package can be integrated with the VISION software package, while the firm has developed interfaces to the VISUM transportation planning system. Users can employ VISUM as a data hub and develop a transportation model that can run in PTV OPTIMA. Using the PTV BALANCE tool allows a traffic-adaptive network to be established, providing a comprehensive view of an entire road network. This will allow signal plans to be calculated for the next five minute time period, which can be optimised and adapted to traffic situations.
