VS-PLUS is a control method for road intersection controlled by traffic lights. The traffic lights are connected to a controller where VS-PLUS runs as a separate process. The software is best suited for traffic-actuated control of an intersection. In order to detect the traffic, a sufficient number of detectors must be connected to the controller. The detector signals are typically scanned 10 times per second. The software is suited as well for implementing public transport priority systems. VS-PLUS does not provide a programming environment but allows the traffic engineer to ''parametrize'' the control. It uses an abstraction model for the necessary parameters such as "desired priority" that can be set as a parameter. VS-PLUS supports the North American NEMA software standard for intersection control. Due to the parametrization capabilities the software can communicate with central traffic computers and implement their current strategy by parameter changes. This enables re-coordination of a Green Wave still keeping the local optimizations. During development and test of the parameters, the control can be simulated on a PC using a microscopic traffic simulator (as TransModeler, VISSIM, AIMSUN, or Paramics). == See also == * Traffic engineering * Road traffic control 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「VS-PLUS」の詳細全文を読む スポンサード リンク
