Optimised Signal Capacity and Delay, Phase-based Rapid Optimisation of traffic signals

OSCADY PRO, is a phase-based traffic signal optimisation program. OSCADY PRO has been developed in conjunction with the Centre for Transport Studies at UCL (University College London). The software makes use of a number of unique optimisation techniques and can be used for isolated junctions, or the results can be exported into TRANSYT for use in linked systems.

OSCADY PRO allows the import of files from OSCADY Classic (previously known as OSCADY 5).

A significant advantage of OSCADY PRO is that it can automatically generate and optimise stages and stage sequences. All that's needed is for the user to supply minimum intergreen times in the form of an intergreen matrix; the program does the rest and calculates all possible optimum stages and stage sequences. From this starting point, the program then produces sets of individual phase timings that maximise capacity and/or minimise delay. Phase delays and repeated greens are automatically handled by the program.

Of course, OSCADY PRO allows the user to input stages manually when an existing junction is being evaluated or when it's necessary to force a particular stage.

TRL wish to acknowledge the valuable support of our partners at the Centre for Transport Studies at UCL in the development of this product.
