摘要
为研究农村人口日常出行距离分布特征,通过实地问卷调查获得农村样本人口出行数据库,结合统计理论,推导出农村人口出行距离分布函数模型,在分析分布函数参数对模型影响的基础上,使用不同省份的两地区农村人口出行数据,对模型进行实证研究和参数误差分析。结果表明：农村人口出行距离分布模型绝对误差小于0.10,具有很强的通用性和实用性;不同地区在使用该模型时,可依据本地情况调整函数取值范围,对中短距离出行较多的地区,出行距离累计分布在10 km以内时可适当增大,增大程度控制在0.10以内;而中长距离出行较多的地区,出行距离累计分布在20 km以内时,可减小0.05~0.10。
To study the trip distance distribution character of rural population in China,the travel database of samples in rural areas was obtained by questionaire survey,then the trip distance distribution function model was analyzed by using statistics theory.Meanwhile,two different provinces rural population trip data were selected to testify the model＇s validity and analyze the parameters error based on the effect factors of the function parameters.The result shows that the absolute error of rural population trip distance distribution model is less than 0.1,the model has generality and practicability.Different regions can adjust value range of the function when use the model.For the area with high percent of middle and short trip,the cumulative distribution can increase properly in less than 10 km,and the enlargement can limit of 0.1.For the area with high percent of long trip,the cumulative distribution can decrease between 0.05 and 0.1 in the scope of 20 km.4 tabs,4 figs,6 refs.
