Goal and impact

The model supports mobility policy choices. The results influence the design of public space and traffic regulations, such as speed limits. In addition, the results are used for environmental calculations, such as noise and emission calculations.

Considerations

This approach makes it possible to transparently inform policy choices for future developments.

Human intervention

All inputs and outputs are checked and interpreted by experts. Output is never copied one-to-one to inform a decision.

Risk management

The risk of wrong policy choices based on the model is minimised.

Operations

Data

  • Generalised socio-economic data (inhabitants and jobs at postcode 4 level)
  • Network file of the road network
  • Scenarios of the CPB
  • Traffic counts

Technical design

The traffic model works with a continuous trip per person per day, taking into account all forms and combinations of trips, such as bicycle, car, public transport, shared transport and walking.

  • The risk model (the algorithm) helps choose which NOW applications to investigate further. It gives clues as to whether the information given in the NOW application is correct. With these indications from the risk model, SZW reviews the application.

  • This algorithm has a low impact. Traffic information systems collect information about the traffic, or provide information to the traffic. They also regulate traffic with rollovers, pollers, barriers, etc.

  • This model, also called the Traffic Safety Meter, maps the regional road safety risk themes. It is based on the twelve risk themes defined in the 'Utrecht Traffic Safety Survey' and the RUA. Available to all road authorities in the province of Utrecht (municipalities, water board and province).
