Example service and resilience targets for an earthquake event

Intervention costs/service measures	Target type	Description	Target	Measurement
Intervention costs	Maximum increase in intervention costs	The costs of the emergency measures	Maximum emergency budget: €2 000 000 per event	By way of the bookkeeping system of the infrastructure owner
Intervention costs	Maximum total intervention costs	The total costs incurred until the travel time service is returned to normal	Maximum total costs: €4 500 000 per event

Travel time	Maximum decrease in service	The increase of travel time after an earthquake event	Below 45 min per trip	By way of automated traffic flow monitoring system
	Shape of losses of service curve during restoration	The way in which travel time returns to normal after an earthquake event	Within 1 week after the earthquake: max delay of 30 min per trip Within 3 weeks after the earthquake: max delay of 15 min per trip
	Maximum allowed restoration time	The total time from onset of the earthquake event until normal travel time	Within 12 weeks after the earthquake: no traffic delays
