| Research Abstract |
(1) Optimal funding for an individual transportation project is the policy mix of toll level and subsidy such that the marginal cost (mc) of tolling equals to the mc of subsidy funds. (2) Optimal toll expressway length and its funding is the policy mix of construction length, toll level and subsidy such that the marginal benefit-net expenditure ratio, the marginal cost (mc) of tolling and the mc of subsidy funds are all equal. (3) Optimal ordinary road length and its funding is the policy mix of construction length and road related tax level such that the marginal benefit-net expenditure ratio, the marginal cost (mc) of road related tax and the mc of subsidy funds are all equal.
