公交运行对行驶车速影响的实验研究

Experimental Research on Influence of the Public Transport on Traffic Speed

行驶车速 (或时间 )与其影响因素之间的函数关系一直是交通流特性研究的重点。本文在对实测数据分析研究的基础上 ,认为公交车在站台的停车情况对路段行驶车速有显著的影响 ,道路的交通条件越好其影响越明显 ;然后经过严密的数学论证得出结论 :在某些道路上公交停车次数而不是机动车流量是决定行驶车速的主要因素 ;最后给出了以交通量和公交停车次数为自变量的二元线性回归公式 。

The functional relationship between traffic speed and its factors is the emphasis of study on traffic flow all the while. It's considered that bus parking at the bus stop has a prominent influence on traffic speed based on the field test data, the better the roadway's condition will be, the more obviously the influence will be. The conclusion is reached after the mathematical reasoning: It's not the traffic flow but the parking times of bus that become the primary factor influencing the speed in some types of roadways. At last, the linear regression expressions with two variables traffic flow and parking times are reached, with strict test check.
