摘要
公路交通量不均匀系数作为公路工程可行性研究和公路网规划中样本OD资料扩大的重要参数,直接影响到基年OD产生的精度。文章收集了广东地区2007年详细的交通量调查资料,采用统计分析的方法,按不同等级、不同地区对各种车型的周和月不均匀系数进行分析,找出不均匀系数的分布规律,作为公路可行性研究和公路网规划工作中参数取值的参考。
The coefficient of dishomogeneity in highway traffic volume is an important parameter as the feasibility study of highway project and the sample OD extending data in the planning of highway network,it affects directly the base year data accuracy.The surveyed data on the detailed traffic volume in Guangdong Province in 2007 was collected in this article,and the dishomogeneity coefficient was examined with statistical analysis method in a week or a month for all type of vehicles in the different grades and areas,to find out the distribution law of the coefficient as reference to take values of coefficient in the feasibility study and the planning work of highway network.
