you can do a second render with advanced tab - depth render.

You will get a black and white depth mask. looks like the attached image.

Then can can blur in photoshop whatever you want..

Your concept looks promissing and, of course, I like the tramway

It is called Depth of Field or DOF
Joke gave good advice.

If your goal is a quicker rendering but to create the DOF (blur depth of field) effect in post-pro,
  1. In Twilight Render, make a rendering without any DOF.
  2. Save this image. "render"
  3. Render again using the Tech>Specialized>Depth Render pass in the Technical render settings.
  4. Save this image "depth"
  5. (render this image at double the resolution for better quality depth render, then resize it to match rendered image in photo editor.)
  6. Open Photoshop >Open "render" image.
  7. Open "depth" image.
  8. Duplicate the "render" image to Layer1, and create a mask on that Layer1.
  9. Select all on the "Depth" image and CTRL-C copy that image
  10. Alt-click the Mask on Layer1 of the Render image, and now you should see all white mask.
  11. CTRL-V paste the depth render into that Mask.
  12. Filter>Distort>Lens and choose in the settings for the filter the source to be the "layer mask".
  13. Try changing the different blur settings.
