JCT Consultancy quickGreen v2.0.3.0
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 automatically locate intergreen conflict points and measure distances between stop lines and conflict points, as required by the calculation method described above. This results in X distances for the critical conflict points.
Traffic signal Phases are added to group lanes controlled by the same Phase.
The critical X distances are used to calculate a Phase Intergreen Matrix using the lookup table in the UK Traffic Signs Manual, Chapter 6.
Calculated intergreens can be overridden and adjusted if necessary and notes can be added to explain why adjustments have been made.
The Intergreen Matrix can be exported to LinSig or other signal design software.
Traffic - Pedestrian and Pedestrian - Traffic Intergreens can also be calculated.
A detailed PDF report showing how the intergreens were calculated as well as the final Intergreen Matrix can be produced.
quickGreen can easily accommodate changes to Junction geometry. As lanes or turn paths are moved conflict distances and intergreens are instantly recalculated allowing the effects of changes to Junction geometry to be quickly evaluated.

JCT Consultancy LinSig v3.2.33.0
JCT Consultancy was formed in the 1980s to develop and market the LinSig software package for Traffic Signal Design and to provide specialist traffic signal related consultancy advice to local authorities, consultants and central government. Since then further traffic engineering software products have been developed, and a comprehensive programme of training courses has been set up both to support the software and to teach general traffic signal design techniques. Still based in the historic City of Lincoln, JCT now employ a team of traffic engineers and software engineers who combine to provide world-class engineering services.
LinSig 3 is a major new version of LinSig and has been available since mid 2009. It adds many new features and extends the software in a number of significant directions. Since its original release in 1985 LinSig has been the UK industry standard software for the assessment and design of traffic signal junctions. Its unique attribute was and still is the combination of both traffic and controller modelling for comprehensive traffic signal design. The software has been instrumental in advancing UK phase (signal group) based methods of control giving maximum safety and efficiency for all road users.
One common application of LinSig is rapid testing of new traffic signal schemes which involve large numbers of alternative options. LinSig allows different options to be quickly modelled and rejected or taken forward possibly to more detailed resource intensive modelling such as microsimulation. Other common uses of the software include the interactive design of signalled roundabouts for which it is strongly established in the UK and overseas, transport assessments for land development and detailed modelling of networks of signal, priority and roundabout junctions.
