How do I fix the length of a stage that has traffic on it?

Question: I’d like to know how to fix the length of a stage that has traffic on it. The particular stage mostly has pedestrian phases running but also has a vehicular traffic phase running too; hence the need to ensure the optimiser does not try to favour traffic during optimisation.

Answer:

TRANSYT 15 and TRANSYT 14:

Although you cannot add a stage maximum, you can set a maximum green time for the relevant phase. This should be sufficient for you to resolve this issue.

TRANSYT 13:

A maximum value cannot be applied in TRANSYT, while a minimum CAN be set, i.e. the “User Stage Minimum” in T13Mode). Therefore the only way is to add a VERY NEGATIVE delay weighting to the traffic link (i.e. favours delay!) so that the TRANSYT optimiser is discouraged from adding green time to it.
