大数据所涉及的信息量规模巨大,大数据技术使得人类认识世界的思想及方法发生变革。智慧物流是利用集成化、智能化、移动化技术,使物流系统具有思维、感知、学习、推理判断和自行解决物流中的某些问题的能力,它包含了智能运输、自动仓储、动态配送及智能信息的获取、加工和处理等多项基本活动,为供方提供最大化的利润,为需方提供最佳的服务,同时也应实现消耗最少的自然资源和社会资源,从而形成完备的智慧物流综合管控体系。论坛的主题是大数据与智慧物流,面向大数据技术在智慧物流领域的应用问题,着重研讨大数据背景下智慧物流体系、理论和方法,推动我国现代物流行业健康有序协调发展。     

城市交通与信息化

信息技术的不断发展为城市交通运行改善带来新的契机,城市交通与信息化是一个对中国未来城镇化模式影响非常深远的命题。首先从道路交通管理、公共交通服务、交通综合信息平台等六个方面阐述中国交通信息化的发展状况,总结交通信息化在信息采集、数据分析、决策支持、信息发布以及社会关注五个方面的发展趋势。指出交通信息化应更关注城市交通、都市圈交通的特点,在认识城市交通本质和服务对象的基础上进行总体设计。最后,强调智能交通信息化发展目标应与城市整体发展目标相一致,应考虑公众、企业、政府层面的不同诉求进行交通信息化的顶层设计。

综合交通枢纽智慧停车场的建设可以实现枢纽客流的快速疏散,提高枢纽运行效率,降低管控压力。目前交通枢纽停车场的建设更注重停车场自身运营管理中智慧系统的建设,但对旅客停车出行链缺乏一体化融合,对周边交通缺乏一体化协同,并出现多主体管理缺乏信息交互的情况。结合智慧停车场功能需求,研究实现功能需求的关键技术,希望为综合交通枢纽智慧停车场建设提供经验借鉴与思考。     

Innovative strategies for urban car-sharing systems and a simulator to assess their performance

In this paper, three innovative car-sharing systems for urban areas are proposed, based on fleets of individual intelligent vehicles with three service characteristics: instant access, open-ended reservations and one-way trips. These features provide high flexibility but create an uneven distribution of vehicles among stations. Therefore, relocation of vehicles must be performed. Three different system procedures are proposed: in the first system, relocations are performed by users; in the other two, vehicles relocate automatically, thanks to their automation. In the first two systems, vehicles are accessible only at stations, whereas in the third they are also accessible along roads. In order to provide transport managers with a tool to test systems in different realities, an object-oriented simulator is developed. The simulation provides outputs of system performance, in terms of user waiting times and system efficiency. The proposed systems are simulated for the city of Genoa, in Italy, and a comparative analysis is presented.     

An integrated framework for embedding large-scale dynamic traffic assignment models in advanced traveler information systems

In recent years, increasing attention has been drawn to the development of various applications of intelligent transportation systems (ITS), which are credited with the amelioration of traffic conditions in urban and regional environments. Advanced traveler information systems (ATIS) constitute an important element of ITS by providing potential travelers with information on the network's current performance both en-route and pre-trip. In order to tackle the complexity of such systems, derived from the difficulty of providing real-time estimations of current as well as forecasts of future traffic conditions, a series of models and algorithms have been initiated. This paper proposes the development of an integrated framework for real-time ATIS and presents its application on a large-scale network, that of Thessaloniki, Greece, concluding with a discussion on development and implementation challenges as well as on the advantages and limitations of such an effort.
