Save prediction formula

  1. Identify the model that best explains pedestrian movement
  2. Fit model
  3. Left click on Response -> Save Columns – > Prediction Formula A

Save prediction formula on existing

  1. A new Prediction formula column should appear
  2. Right click on the prediction formula column.
  3. Press formula
  4. A formula should appear. This is the predicted formula for the urban performance model.
    Ie. Ex_Pedmov = B0  + B1*NACh + B2*StepDepth B
  5. Copy down this formula
  6. Now you have gotten the existing observed and existing predicted pedestrian movement figures.

Apply prediction formula on existing

  1. Open GIS table from previous applications.
  2. Table -> Maintenance – > Table Structure
  3. Create new columns call it existing predicted pedestrian movement C
  4. Add field -> existing_predicted
  5. Update columns using the saved formula D
  6. Table -> Update Columns
    ie. LogPedmov = 0.131908 + (0.35866*LogCh)

Apply prediction formula on proposed

  1. After creating the urban performance model for existing, you could now apply it on the proposed design.
  2. The proposed urban performance forecast model must follow the same parameters as the existing urban performance model.
  3. For example if the existing performance model uses the following formula;
    Existig Ped_mov = Log (Existing_Ch) + Log(Existing_Step depth from Tube Station)
  4. Then the proposed performance model must keep the same parameters as the proposed model using the following formula;
    ie. Pr_pedmov = Log(Proposed Ch) + Log(Proposed Step depth from tube station)
  5. Thus for the proposed design in this case both proposed choice and proposed step depth from tube station must be calculated. Please follow step 1 and 2 for the recalculation of these measures. E and F
  6. You should now be able to calculate a proposed predicted movement.
