摘要
动态交通信息服务是社会化特征显著的智能交通系统理念中的重要组成部分之一,也是提高基于位置服务可用性的核心所在。动态交通信息服务的实现,需要在实时交通信息获取与微观交通仿真技术的基础上,构造各种应用模型和算法,并与地理信息系统环境下的交通信息管理与发布平台相结合,提供满足公众需求的信息服务,为公众出行、交通管理、物流运输等应用提供有效支持。目前业界存在几十种微观交通仿真模型和对应开发的微观交通仿真平台。这些模型和平台有着各自不同的特性,对地理信息系统的支持能力也存在很大差异。本文分析了SimTraffic、CORSim、VisSim、Paramics、AIMSUN、MITSimLab和TransModeler等7种几种业界成熟的微观交通仿真平台的技术特性,评价了它们对地理信息系统的支持能力,可为动态交通信息服务应用的研发提供有效参考。
Dynamic traffic information service is one of the most important components in the concept of Intelligent Transportation System, which has a notable feature of socialization, and is the core to enhance the usability of Location-based services. To realize dynamic traffic information service, all kinds of applying models and algorithms should be constructed, and be combined with traffic information management and publishing platform, on the basis of obtaining real-time traffic data by microscopic traffic simulation. Ultimately, the models and algorithms can provide satisfied tri Pinformation services for the public, and support effectively public trip, traffic management, transport and logistics, etc. Currently there are dozens of microscopic traffic simulation modes in the transportation field. Various microscopic traffic simulation models and the corresponding systems developed have different characteristics and ability to support GIS. The paper analyzes technical features for seven mature microscopic traffic simulation systems in transportation field, such as SimTraffic, CORSIM, VisSim, Paramics, AIMSUN, MITSIM and TransModeler. It also evaluates their ability to support GIS, which could provide a reference for study and development of dynamic traffic information services.
