什么是出行即服务(MaaS)

随着通信技术、计算机技术、车辆技术的快速发展，物联网、互联网、车联网逐步形成并广泛应用，乘客、驾驶员、调度员、车辆、道路、出行环境及云端得以高效联通，智能网联、自动驾驶等新兴技术得到蓬勃发展，巨量时空大数据随之产生与获取，城市交通的发展进入了新技术时代.同时，在可持续发展目标的引领下，出行即服务、共享出行等新兴理念伴随着新兴技术的发展正逐步颠覆现有的城市交通运行场景与运营管理模式，相关理论研究与实践探讨将是未来一段时间内城市交通管理与服务领域的发展方向与研究重点.在总结城市交通发展机遇与挑战的基础上，首先分析了新技术时代解决城市交通管理与服务问题的新思路.随后，分别从交通大数据、共享出行、网联自动驾驶3个方面对城市交通管理与服务领域最新研究成果进行了全面的总结与综述.最后，梳理了新技术时代城市交通管理与服务的相关研究方向.

Integrated co-evolution model of land use and traffic network design

With the rapid development of communication technology, computer technology, and vehicle technology, the internet of things, the internet, and the internet of vehicles have gradually formed and are widely adopted. Passengers, drivers, dispatchers, vehicles, roads, travel environment, and the cloud can be connected efficiently. The emerging technology developed rapidly, such as intelligent interconnection, autonomous driving, etc. Besides, the big spatial-temporal data was generated and collected. The development of urban transportation has entered a new era. Meanwhile, under the guidance of the sustainable development goals, the development of emerging concepts such as MaaS, intelligent interconnection, autonomous driving, and sharing mobility are gradually subverting the existing urban traffic operation scenarios and operation management models. Related theoretical studies and practical discussions will be the development direction and research focus of urban transportation management and services in the future. Based on the summary of the opportunities and challenges of urban transportation development, the new ideas of solving urban transportation management and services problems in the new era was first analyzed. Then, the three aspects of transportation big data, sharing mobility, and connected autonomous vehicles were separately analyzed. Accordingly, the latest research on urban transportation management and services were comprehensively summarized. Finally, the related research directions of urban transportation management and services in the new era were sorted out.
