旅游型中小城镇车辆速度与加速度分布特性研究
|
摘要
以旅游小城韶山为例,通过调查本地驾驶员和外地驾驶员在不同道路类型上的逐秒GPS数据,运用统计学方法对不同驾驶员类型、道路类型的车速分布特性进行了研究。首先,通过对车速的分布形式进行拟合,定性分析了不同驾驶员与类型道路的车速分布形式及其变化规律;然后,从驾驶员类型、道路类型两个角度对车速分布的集中趋势、离散程度以及加速度分布进行了分析。结果表明,驾驶员类型与道路类型对车速与加速度分布的形式以及参数值有着不同程度的影响,大多情况下旅游城镇车速分布较为符合正态分布,由于道路熟悉程度以及出行目的差异,本地驾驶员平均车速更高,不同驾驶员在景区车速分布特性差异更为显著。研究成果将对旅游型中小城镇交通的规划、设计、控制、管理以及评价提供科学依据和数据支持。
The study is based in a tourism oriented town,Shaoshan,where second by second GPS trajectory data of automobiles,driven by local drivers or tourists,was collected on different road types. The data was then processed to produce the speed distribution characteristics by general statistical methods corresponding to the driver and road types. First,the speed distribution forms of different driver and road types were qualitatively analyzed by fitting the survey data. Second,the central tendency and dispersion degree of the speeds plus acceleration distributions were analyzed from the drivers and the road types. The research results show that different types of drivers and road types have different degrees of influence on the form of vehicle speed and acceleration distribution and parameter values. In most cases,the speed distribution of tourism towns is more in line with the normal distribution. Due to the familiarity of roads and differences in travel purposes,the average speed of local drivers is higher than foreign drivers,and different drivers have more significant differences in the distribution characteristics of the speed in scenic area. The results would provide a scientific basis and data support for planning,designing,controlling,manageing and evaluating of a Tourism oriented town traffic.
