Goal and impact

  • The model supports policy choices on cycling mobility.
  • The outcomes influence the design of public space and traffic rules, such as right of way.

Considerations

This algorithm 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

Human intervention minimised the risk of wrong policy choices based on the model.

Operations

Data

  • Generalised socio-economic data (inhabitants and jobs at postcode 4 level)
  • Network file of the road network
  • Data on travel behaviour from CBS research
  • Scenarios of the CPB
  • Traffic counts

Technical design

The traffic model works with a continuous trip per person per day and only depicts cycling behaviour.
