British industry is littered with hte ruins of engineering companies where they let the accountants and lawyers take over: excluding the actual engineers from senior management in many cases.

When you look into the details of these calculations (this is certainly true for HS2 in hte UK and I would be absolutely astonished if it is different elsewhere, as this is the standard method) the standard value ascribed to the time is the average pay of the people doing the travelling.
