A device for computing a traffic index necessary for computing a signal control parameter, comprises a first computation unit which computes normalization data which is expressed as a ratio of an entrance road traffic variable of an intersection of interest to a saturation traffic flow; and a second computation unit which, by using the normalization data, computes the traffic index which is defined with an expression in which the entrance road traffic variable is included in the numerator and the saturation traffic flow is included in the denominator.
一种用于计算信号控制参数的计算所需的交通指标的装置,所述装置包括:第一计算单元,其计算被表示对象交叉路口处的流入道路的交通变量与饱和流率的比率的归一化数据;以及第二计算单元,其通过使用归一化数据来计算在分子中包括流入道路的交通变量并在分母中包括饱和流率的公式定义的交通指标。
