摘要: 利用交通模型为多用户与多场景提供共享服务是大数据背景下交通模型发展面临的巨大挑 战。以深圳市交通仿真系统三期工程为例,提出以交通模型体系为核心、以多源交通大数据为底 座、以模型参数与规划决策指标自动标定为支撑、以模型共享服务为导向全流程集成的信息化仿真 系统架构,以实现复杂交通数据环境下模型高效共享服务的目标。以交通土地在线协同系统为例阐 述模型共享服务的技术方法,面向法定图则修编、城市更新规划两类存量用地规划需求,构建中观 尺度多种交通方式评估模型;从简化模型操作、保障数据安全的视角,交通模型系统采用基于B/S 的云服务架构,包含用户端的项目评估申请、评估管理、评估结果和项目审核,以及服务端的数据 与地图服务接口、模型与方案数据中间件转换、平台数据存储管理、交通模型仿真调用等功能。实 践表明,共享服务理念下的深圳市交通模型系统扩大了模型应用范围,能较好地支撑规划多场景、 多用户定量评估需求。

Abstract: In the context of big data, developing a transportation model that can provide shared services for multiple users and scenarios is substantially challenging. Taking the third phase of Shenzhen traffic simulation system project as an example, this paper presents an information-based simulation system architecture. The proposed architecture aims to achieve efficient shared services of the model in a complex traffic data environment. It integrates the entire process, centering on the transportation model system and leveraging multi-source traffic big data. It is supported by the automatic calibration of model parameters and planning decision indicators, with a focus on shared services of the model. Using the online transportation land coordination system as an example, the paper describes the technical approach for the model shared services. It also builds an evaluation model for mesoscale multi-modal transportation, addressing two types of planning demands of stock land: statutory map revision and urban renewal planning. To simplify model operation and ensure data security, the transportation model system adopts a B/S-based cloud service architecture. It offers user-side functions such as project evaluation applications, evaluation management, evaluation results and project reviews, as well as service-side functions such as data and mapping service interfaces, middleware transfer of model and plan data, storage and management of platform data, and simulated calls of the transportation model. The practice shows that the shared services concept has expanded the application scope of the Shenzhen transportation model system and provided better support for quantitative assessment needs for planning across multiple scenarios and users.
