Insight into travel document turnover

To ensure that Rotterdammers do not have to wait too long at the counter for their travel documents, it is necessary to predict how busy it will be. This algorithm predicts the number of travel documents to be requested by Rotterdammers, on which the planner bases the number of employees to be deployed.

Goal and impact

PURPOSE: The timely provision of travel documents to Rotterdammers so they can comply with their identification obligation.


IMPACT: The algorithm's impact on residents and businesses is low. It complements the current planning process. The algorithm is designed to predict the number of people at the counter in order to minimise Rotterdam citizens' waiting times and make the best use of our capacity. To do so, we use minimal personal data and take appropriate measures to mitigate risks.

Considerations

Processing the personal data to predict the demand for travel documents is an invasion of privacy, the impact and residual risk of which is low. The purpose is to provide timely travel documents to Rotterdammers so they can comply with their identification obligation. Setting this against the low impact and residual risk, the use of the data for this purpose is proportionate.

Human intervention

There is always human supervision by the Direction & Planning team and the Management Team. The planner also interprets the results of the application.

Risk management

Field not filled in.

Legal basis

The processing is necessary for the performance of a task carried out in the public interest.

Elaboration on impact assessments

Work sessions were convened to carry out the DPIA. The outcomes of the working sessions confirmed that the risks are limited.

Data

The following data will be used:

- birth dates

- expiry date of travel document and date of retention,

- number of missing travel documents per day

- number of Rotterdammers becoming Dutch citizens per day


Technical design

To ensure that Rotterdammers do not have to wait too long at the counter for their travel documents, it is necessary to predict how busy it will be. We do this using this algorithm. The algorithm looks at the number of expired travel documents, the average number of lost travel documents, but also at how early a person applies for a new travel document. It also monitors births, deaths, naturalisation and other factors. Based on all these data, a prediction is made of the number of Rotterdammers who pass by on a day to apply. This is expected to produce better predictions than the standard model (NVVB), ultimately resulting in shorter waiting times for Rotterdam citizens.
