Goal and impact
The application aims to contribute to the improvement of road safety in the province of Utrecht. The algorithm is a tool to obtain more, better and faster insights into traffic safety from a large number of different datasets. The results of the application are used to advise traffic experts on (policy) choices that reduce the risk of traffic accidents. This allows policy officers to detect high-risk locations, prioritise them, propose them for subsidy and monitor the development of risks over time.
Considerations
The model is directly linked to and reflects priority, regional road safety risk themes. The application's advantage with this is that it allows practical elaboration of established policies. Here, various facets can be combined and weighed against each other. The disadvantage is that the results of the model must be interpreted properly by users. Not all existing road safety risks can be expressed in data/risk indicators, and data may contain errors.
Human intervention
The algorithm is an analytical tool. The outcomes are advisory and thus interpreted and verified by humans. Model outcomes are never adopted 1-to-1. So there is no automated decision-making.
Risk management
Nationally established datasets are used as much as possible. Data quality is checked periodically and, where possible, updated annually. A disclaimer is in place stating that sources may contain incorrect or not up-to-date information. In addition, extensive documentation is available on the structure, content and use of the application. The results are always reviewed by a traffic expert before use. Finally, no personal data are processed or displayed.
Legal basis
The Road Traffic Act (article a4, c),
Road Infrastructure Safety Decree (section 3, et seq.)

Technical design
The system contains 12 risk themes, defined in cooperation with Utrecht road authorities. Each theme consists of one or more indicators (measurable component of a risk) and each indicator consists of one or more variables (characteristic derived from data). Each indicator and risk, based on a weighting framework, is assigned a score between 0 and 1. The final score of a road section is determined by (again) making a weighted sum of all risk scores (also a number between 0 and 1).

- Whereas ordinary traffic lights register by detection loops (sensors in the road) that traffic is passing over, 'smart' traffic lights additionally register via apps what kind and how much traffic is coming. This allows traffic lights to see traffic "arriving" earlier and thus determine how long the traffic light is on green.Last change on 2nd of April 2025, at 14:10 (CET) | Publication Standard 1.0
