3月28日下午，应北京交通大学交通系统科学与工程研究院的邀请，香港科技大学土木环境工程系讲座教授、“长江学者”讲座教授杨海教授来到我院交流访问，为广大师生作题为“Credit Charge-cum-reward Scheme for Green Multi-modal Mobility”的讲座。

　　杨海教授基于促进绿色交通，缓解交通拥堵和排放的研究背景，对积分收费奖励机制（Credit Charge-cum-reward , CCR）计划进行了系统阐述，从理论上和数字上证明，所提出的CCR方案通过收费和奖励率以及差异化的收费和兑换价格来调节出行者的定期模式使用行为，从而灵活地促进多模式的出行需求管理。报告期间，杨教授还与在场师生们进行了热烈的讨论和交流。

　　报告题目：Credit Charge-cum-reward Scheme for Green Multi-modal Mobility

　　摘要：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.
