This paper has proposed a method to estimate traffic density using the output(traffic flow and time mean speed) of fixed traffic detectors.

本文提出了一种利用定点检测器数据（流量和时间平均速度）来获取交通流密度的方法。

An accident investigator later examined the scene and estimated the speed at point of impact was between 30mph and 35mph which "must mean the approach speed would have been greater", said Mr Lamb.

It will mean a minimum speed of 100Mbps (megabits per second) for secondary schools and 10Mbps for primary and special schools by 2014, the Welsh government said.
