Transport Validation - Adjustement of price sensitivity and FE CHA

[johannah-pik]

Short-term:

• Adjustment of LDV share weight in CHA to meet historical data

Mid-term

• create Mix1..Mix4 that adjust tech/policy lever strength from very weak to very strong, to be used for ~NPI, NDC, PkBudg1520, PkBudg870 (all SSP2)

• create (rough) overview of levers and their settings in Mix and Conv, to prepare the discussion how to set them in NewMix1..NewMix4 (with NewMix1 probably similar to Conv, and NewMix3 similar to Mix) prepare table with proposed lever settings for NewMix1 .. NewMix4
  test proposed lever settings

• (Possibly): create interpolation of the 4 Mix settings, so that when we have targets in between, there is no discrete jump in policy strenghts but rather a continuous change. This might be matched to budget size, but this may cause problems when doing delay runs where a scenario is fixed to another scenario and then tries to meet the old budget - this will lead to much higher carbon prices (and thus policy stringency), but the budget wouldn’t change. Therefore, it may be advisable to map from carbon prices to technology strength
