加拿大阿尔伯塔省土地利用交通模型的发展

摘要

加拿大阿尔伯塔省经济的飞速发展,使得为全省制定合理的交通规划成为一项迫切的任务,在这种情况下,本文提出了全省的土地利用交通模型.该模型以PECAS(生产、交易和消费分派系统)结构为基础,实质是在整体经济的前提下考虑基本的交通需求(商品、服务、劳动力交换的流通过程)而进行交通规划.生产、交易和消费分派系统是一种空间经济模拟系统,它侧重交通规划和发展规划,近几年在美国提出并在一些州和城市得到应用.阿尔伯塔省土地利用交通模型受其模型建立基础,尤其是MEPLAN和TRANUS模型的影响,但该模型在理论基础和行为描述上都做了明显的改进.本文从数据源和标定方法方面介绍加拿大阿尔伯塔省的土地利用交通模型的建立和发展.%The rapid economic growth in Alberta, Canada makes statewide transport planning a pressing task. A statewide land use transport model is developed at the University of Calgary to satisfy such a need. The model is based on the framework of PECAS((P-)roduction, (E-)xchange, (C-)ommodity (A-)llocation (S-)ystem). The virtue of such a system is that it brings the transportation planning in the context of the whole economy by considering the fundamental transport demands: the exchange of goods, services, and labor. The PECAS framework is a spatial economic simulation system with a focus on transportation planning and land development planning, which has recently been developed and applied in a number of states and metropolitan regions in the United States. It has the draw from the previous models, especially MEPLAN and TRANUS, and provides significant improvements on theoretical basis and behavior representation. This paper describes the design and development of such a model for the Canadian province of Alberta in terms of its data sources, novelty, and strategies for further calibration.
