JCT Consultancy quickGreen

QuickGreen is an innovative software tool to help signal engineers measure and calculate phase intergreens for traffic signal junctions. The software is designed not only to speed up the measurement process but also to reduce errors, improve the ease of checking of intergreens and assist with archiving intergreen calculations. The quickGreen process for determining intergreens is as follows: A drawing of the junction is imported into quickGreen from any of the usual sources including AutoCAD, a PDF, satellite imagery or even a scanned drawing. After importing the drawing is calibrated to a known scale within quickGreen. Lanes, Turning Movement Paths, and Pedestrian Crossings are added by overlaying them on the scaled drawing. Turning Movement Paths can be easily refined to fit any geometry using typically one or two control points on the path. As the model is built up, quickGreen will au
