武汉市公共交通信息系统建设与应用

全方位掌握公共交通运行现状和精确预测客流变化趋势是城市公共交通规划研究的重要前提，其时效性和准确性不仅关系到信息发布，还对预测模型的精度产生直接影响。为有效服务政府决策并科学指导公众智慧出行，运用智能化手段建立公共交通信息系统，其具有线网性能分析、客流监控预测、运行状态评估等功能。在整合武汉市公共交通信息资源的基础上，公共交通信息系统建立时空匹配算法判断乘客上车位置，通过车站吸引强度以及出行链模型模拟乘客下车站点，建立基于动态信息的公交运行评价指标体系等。抽样调查结果表明系统性能达到预期要求。同时，探索运用系统各项量化指标服务于城市公共交通线网优化调整、换乘优惠政策制定以及日常运营管理，为创建公交都市示范城市，落实公交优先发展战略提供技术支撑。

Development and Application of Wuhan Public Transit Information System

Comprehensively understanding current statues and accurately forecast trends of public transit passenger volume are important prerequisite for urban transportation planning. The timeliness and preci-sion not only affect information release, but also determine the accuracy of forecasting model. In order to better support government decision-making and develop a smart traveling system, the elements of public transit information system should include network performance analysis, passenger patronage monitoring and forecasting, operation status evaluation, and so on. This paper demonstrates Wuhan’s efforts in devel-oping public transit information system using Space-Time matching algorithm to infer boarding locations and using ABM philosophy to infer alighting locations. Survey results indicate that the proposed system can offer the qualified estimations. Additionally, the paper also explores to apply the quantitative indicators generated from this system to optimize the urban public transit network, study transfer policies and manage daily operation to some extent. Those attempts are further regarded as active efforts in building a public transit metropolis and implementing public transit priority development strategy.
