veh_op_costs: Calculate vehicle operating costs over full appraisal period

In DanBoyB/cba: A collection of tools for simple cost benefit analysis of simple road realignment schemes

Description

A function to read in appraisal paramaters, fuel and non-fuel costs calculated and traffic projections to calculate scheme vehicle operating costs

Usage

veh_op_costs(opening_yr, appr_period = 30, resid_period = 30, disc_rate,
  price_base_yr = 2011, ave_veh_occ = 1.2, traffic_proj, speed_ex,
  speed_prop, fuel_costs, non_fuel_costs)

Arguments

opening_yr	The proposed year of scheme opening
appr_period	The standard appraisal period in years
resid_period	The residual value period in years (in addition to the standard appraisal period)
disc_rate	The test discount rate as a decimal
price_base_yr	The price base year assumed for the appraisal. Defaults to 2011
ave_veh_occ	The average vehicle occupancy (persions per vehicle)
traffic_proj	A dataframe of annual traffic flow projections
speed_ex	Average speed on existing route in kph
speed_prop	Average speed on proposed route in kph
fuel_costs	Table of fuel costs generated by fuel_costs_km function
non_fuel_costs	Table of non-fuel costs generated by non_fuel_cost_km function

Value

A dataframe of discounted scheme benefits
