How to add a dynamic traffic model

Dynamic traffic model

A dynamic model changes (over time), according to changes in the 3D world. An example of a dynamic traffic model is a model in where is calculated how the traffic intensity changes when building a certain amount of houses. Effectively the TRAFFIC_FLOW attribute of the roads will be updated with a new value, when building houses in the Tygron Platform. To create such a model, first create a Geojson file with the roads that will be changed by a certain Action or Measure and import the file. In an Excel file, the calculation for how much and when the traffic intensity changes has to be made. This file can be uploaded as either an indicator or panel. The indicator or panel explanation text in this case is not relevant. The Excel is only used to define the model and import it in the Tygron Platform.

The Excel implementation of a simple dynamic traffic model, consists of the following consecutive steps:

• Retrieval of the original traffic density in Area X - SELECT_ATTRIBUTE_WHERE_NAME_IS_TRAFFIC_FLOW_AND_AREA_IS_X

• Calculation in an excel file, with the new traffic density as outcome - original traffic density + change

• Output of the new traffic density for constructions in Area X - UPDATE_BUILDING_TRAFFIC_FLOW_WHERE_AREA_IS_X
