区域交通模型建设思考——以广东省综合交通模型为例

中国区域交通一体化迫切需要开展区域交通模型研究,而传统交通模型建模方法在数据基础、调查方法上的不适用性造成区域交通模型的研究多停留于理论层面.打破传统的交通建模基础数据需求,明确多层次空间模型体系,依托高速公路联网收费数据,铁路、水运、航空等监测数据构建广东省综合交通模型.阐述在有限基础数据的背景下广东省综合交通模型框架、路网设置特点、交通分区方法、出行频次模型、目的地选择模型、区域货运模型等建模的关键技术方法.

Regional Transportation Model Development: A Case Study of Guangdong Comprehensive Transportation Models

Current regional transportation integration in China urgently needs research on regional transpor-tation models. However, the data and survey methods for traditional travel demand modeling methods are not applicable to the integrated regional transportation system, which has made the regional model develop-ment only exist at theoretical level. By going beyond the data requirements for traditional transportation models, this paper develops Guangdong comprehensive transportation models with a multi-level spatial structure using the highway ETC data and monitoring data from railway, water transportation and air trans-portation. The paper elaborates the crucial techniques of Guangdong comprehensive transportation models with limited data in several aspects:model structure, network setting principles, traffic zoning, travel fre-quency model, destination choice model, regional freight model, and etc.
