    Hi taylor,

    Is it possible to link passenger travel demand to both population and per capita GDP using the GrowthAs(.....) syntax or any other function directly in the LEAP?

    Is GrowthAs() only for a single variable?

    We can do it in an excel sheet but it will be very convenient and time saving if it can be directly formulated in the LEAP- expression.

    thanks for your time and continued support.


    Dorji

    Hi Dorji,

    A similar question has been answered in the following thread (refer to the fourth post in the thread): https://www.energycommunity.org/default.asp?action=9&fid=68&TID=3724

    Note that the Growth function combined with the Annual Growth function is like the GrowthAs function.

    Hope this helps!
    Thanks

    thank you Emily for providing the expression to combine two variables to activity projection..

    so the only issue is that we can't incorporate elasticity values in such combined expression.


    thanks

    Hi Dorji,

    I'm afraid there isn't an equivalent GrowthAs function which can incorporate two variables and their elasticity values. However, you can still build an expression that does this. Look at the first two posts in the following thread which covers this topic: https://www.energycommunity.org/default.asp?action=9&fid=22&TID=3779

    Thanks,
    Emily
