1. Definitions

The following definitions is provided as information for use in RSMP and may be simplified from their original meanings.

RSMP Nordic takes no responsibility for the correctness of the definitions.

Red rest
The signal group has no green demand.
Red rest without start order
The signal group isn’t allowed to demand green (green demand held back) without a start order.
Red rest with privilege measurement
The signal group has no green demand but can turn green when other signal groups in the same phase are turning green (signal group status G/0) or are green (signal groups status 1/2/3/4/5). A green demand which arrives late when other signal groups are green according to the above, results in a change to green.
Red with reservation
The signal group is red due to other priority.
Red with request
The signal group waits for signal group status 1/2/3/4/5 of conflicting signal groups to end.
Red with start in own stage
The signal group waits for signal group status 6/7/8/9/N/O/P of conflicting signal groups to end.
Minimum green
The shortest time which can be shown green for each respective signal group, this time can´t be shortened.
Max. minimum green
The signal groups status ”minimum green” should be able to be extended with a traffic controlled variable part up to a maximum “Max. minimum-green”. If one or multiple detector logics are programmed to extend signal group status “Max. minimum-green”, then the detector logics will extend the minimum green time if they are active during red signal picture. Signal group status “Max. minimum-green” should optionally be able to be shortened or not at prioritization.
Maximum green (extension)
The signal group should be able to extend its showing of green through extension, e.g. from detector logics. When the signal group has green demand and status minimum green has ended, the signal group should continue its display of green in status maximum green. Maximum green should be measured in parallel with minimum green up to a maximum “maximum green”. Signal group status “maximum green” should optionally be able to be shortened or not at prioritization.
Green rest
A signal group continues its display of green due to one or multiple signal group/s in the same traffic pattern has more demand for green (signal group status 1/2/3), The signal group has no conflict. It waits to be changed, by the rest mode.
Green passive
A signal group continues its display of green due to other signal groups in the same traffic pattern has more demand for green (signal group status 1/2/3). The signal group has conflict. It waits to change, by conflicting signal group(s).
Fixed past-end-green
When the signal group is ordered to change to red it should be able to continue to be green with a configurable fixed time.
Extra green according to intergreen times
Signal groups remains green if possible, according to the conflicting signal groups
Variable past-end-green
When the signal group is ordered to change to red it should be able to continue to be green during a traffic controlled variable time (O function). Signal group status “Past end green” should optionally be shortened or not at prioritization.
Variable yellow or yellow green
Signal group status ”fixed yellow” can be extended with a traffic controlled variable part “Variable yellow”, the signal group status is usually extended by detector logics. (V function).
Variable red
The fixed red time/intergreen time should be able to be extended with a traffic controlled variable part. It is usually measured in parallel with the fixed time whereby it must be longer to have any effect. (R function)
