One shortcoming, however, is that, except for walking, all other travel modes resulted in an increased averagetraveltime.
缺点是除步行外，各类交通方式的平均出行时间有所增加。

Based on the theory of random effectiveness and urban traffic network, a random model used for computing averagetraveltime in a road network is established.
以随机效用理论为基础，建立了整个路网中车辆在路网容量极限状态下的平均行驶时间模型。

Based on the error analysis of the algorithms based on average speed and averagetraveltime, this paper promoted the urban traffic situation evaluation methods based on probe vehicle data.
