基于GISDK的OD数据集成分析模块的开发研究

OD data Integration and Analysis Using GISDK

交通行业中涉及到的OD数据量大、信息量多,为改变以往OD数据处理效率低、精度不高、交通软件缺少OD调查数据统计分析功能等情况,提出运用主流交通分析软件TransCAD中提供的2次开发工具GISDK,进行OD数据统计处理模块2次开发,结合现状路网,采用平行路法,实现对区域OD数据进行高精度集成的思路。详细介绍采用平行路法集成区域OD数据的过程,实现了运用GISDK函数开发OD数据集成分析模块的功能,并利用实际数据验证了其可行性和有效性。

The OD data are usually of large quantity in transportation planning and analysis.To deal with the low efficiency and accuracy in OD data processing and lack of OD data analysis functions in transportation software,this paper presents a method of using the secondary development tools,GISDK,in the mainstream traffic analysis software TransCAD,to develop OD processing and statistical model.Together with the road network features,a parallel path method is proposed in the paper to achieve high-precision integration of regional OD data.This paper describes both the integration of regional OD data by using the parallel path method,and the implementation of the OD data analysis function.The feasibility and effectiveness of the proposed method have been verified by using the actual data.
