The variation trajectory of liapunov exponents of car - following fleet and the variation orderliness of average speed , average headway and average space on steady condition were discussed 文章从分析城市快速道路跟车行为入手,利用李雅普诺夫特征指数,定性与定量相结合,讨论了跟驰车队中的混沌特性。
Whether major road construction projects will be carried out in the next few years with the aim of reducing the average number of vehicles on each kilometre of road surface and increasing the average speed of vehicles 会否在未来数年进行主要道路工程计划,以减少本港每公里道路的平均车辆数目,以及增加车辆的平均时速?
The quantitative relational expression is obtained about the coefficient of additional pressure loss and the froude number by experiment , and the relation is made clear between the average speed of waste plastics particles and the pressure loss of per unit length 由实验得出废塑料输送管内气力输送附加压力损失系数与弗劳德准数的定量关系式,废塑料颗粒平均速度与单位管长压力损失的关系。
So the dreamlike metro train travels at the average speed of 35 kilometers an hour , passing through the central downtown area of guangzhou where the most population in guangzhou are densely inhabited , the traffic is the busiest and the commercial outlets are highly concentrated 有如一趟梦幻列车,以每小时35公里的平均速度,穿越广州人口最稠密、商业网点最集中、交通最繁忙的市中心腹地。
Based on the experiences of our teaching and research room in intelligent traffic monitoring , a real - time motion detection algorithm is used in our hardware system to detect multiple traffic parameters such as the number of the vehicles and the average speed and so on 论文结合教研室在车流量和车速检测方面的经验,在这个硬件平台上,采用一种基于检测线的快速运动检测算法对车流量检测进行了仿真验证。
