摘要
从交通效率的新视角出发,采用总出行时间来衡量土地利用形态的交通效率和宏观可达性。通过把总出行时间分解为组团内部的出行时间与组团之间的出行时间,推导出指标的函数表达式,并建立了一定经济、土地、人口约束下,总出行时间最小的城市土地利用优化模型。结合城市交通规划模型,提出了能体现土地利用与交通系统循环反馈关系的求解方法,从交通效率最大化或局部最大化的角度,对土地利用—交通系统的一体化规划进行了有益的尝试。
From a new viewpoint of transportation efficiency, authors propose the aggregative total travel time to measure the level of transportation efficiency and macro-accessibility of one given land-use pattern. By dividing the total travel time into aggregative inter-group travel time and intra-group travel time, authors deduce the function of total travel time and establish an urban land-use optimum model, which can maximize the transportation efficiency and macro-accessibility under certain restrictions of economy, land and population. Finally, authors attempt to solve the optimum model from the viewpoint of integrated urban land-use, transportation system planning and propose a solving method which can realize the circular relationship between urban land-use pattern and transportation system.
