Study on Statistical Intervals Chosen for Traffic Flowson Urban Roadways
Chao Gao · Journal of Guangdong Communications Polytechnic · 2008
By using correlation dates of Xueyuan Road and Jingsong Middle Road in Beijing,traffic flows on urban roadways are studied in the paper,the results that based on the analysis of influences to traffic flows on urban roadways which caused by crossroads signal show that the statistical intervals should less than signal cycle of upriver and downriver crossroads. Curvilinear models that choose 20 second,1minute,2minute,3minute,4 minute and 5 minute as statistical intervals are given in the paper,the models which choosing 2 minute,3 minute,4 minute and 5 minute as statistical intervals are more reasonable than others,otherwise,the model that choose 2 minute as statistical interval is more accordant with urban roadway fact,so choosing 2 minute as statistical interval of urban roadway is the best choice.
