To promote green mobility and alleviate congestion and emissions, this study proposes a credit charge-cum-reward (CCR) scheme where the government determines mode-specific credit charging and rewarding rates and redemption and charging prices to achieve regulation objectives. Over a CCR scheme period, travelers choose either driving by consuming credits or taking transit to cumulate credits to minimize individual travel costs. At the end, the individual credit balance will be settled by the government at a charging(redemption) price for credit deficits (surplus). From the perspective of travelers, we consider their heterogeneity in value of time and characterize their periodic mode usage equilibrium by formulating a decision optimization problem. From the perspective of the government, we derive the condition about the differentiated charging and redemption prices for a Pareto-improving and revenue-neutral CCR scheme. We also investigate how the government can leverage differentiated redemption and charging prices and its credit-related budget to achieve certain objectives. We have proved theoretically and numerically that the proposed CCR scheme flexibly facilitate multi-modal travel demand management by regulating travelers' periodic mode usage behavior via charging and rewarding rates and differentiated charging and redemption prices.
