 - the current phase is implicitly available for continuation as long as its maxDur is not reached. Detectors of the current phase get a bonus priority
 - the phase with the highest priority is used with phases coming earlier in the next list given precedence over those coming later

+  - if the traffic light uses [custom switching rules](#type_actuated_with_custom_switching_rules) then the default phase is the **last** value of the 'next' attribute
 - if a particular phase should remain active indefinitely in the absence of traffic it must have its own index in the 'next' list as well as a high maxDur value
 - if an active detector was not served for a given time threshold (param **inactive-threshold**), this detector receives bonus priority according the time it was not served. This can be used to prevent starvation if other phases are consistently preferred due to serving more traffic
