7月16日下午，新加坡南洋理工大学王志伟博士应邀来访我院，并在新主楼A716房间作了题为“The discrete-time second-best dynamic road pricing scheme”的学术报告。报告会由田琼教授主持𓀕、我院相关领域20余名师生参加。
拥挤收费被视为缓解交通拥堵的有效手段🧑🦰，已经在新加坡成功实施多年。拥挤收费的目的主要是为了缓解交通拥堵👆🏽、提高路网利用效率🤚。当道路网络中的任一路段均可实施收费时👇，通过收费可以实现系统最优，得到最优收费策略🙋🏼。然而，现实中的部分道路无法实施收费，王志伟博士介绍了自己在具有限制条件下有关收费的研究，提出了动态的次优收费模型。该模型可以用来制定动态收费方案，从而实现交通流从任意初始状态到期望状态的演化🤴🏻🎢。
报告过程中👩🏻🏫，与会老师不时与王博士就相关问题进行交流和探讨✊🏽；报告结束后，与会人员还就相关问题与王博士进行了深入的交流🧑⚕️。王志伟博士还分享了自身科研和工作经历𓀈🧜🏽♂️，结合实际🐥，从学习、工作、生活等方面为到会学生提了诸多有益的建议👱🏻。
