...挤状态的适当指标， 通常采用观测比较容易的占有率来代替交通密度 空间占有率（space occupancy） 时间占有率（time occupancy） (%) 100 × = ∑ X l O i i s (%) 100 ) / ( × = ∑ T v l O i i i t l i X 观测区间长度 v i T 观测时间长度 交通量、密度、速度...
The measurement accuracy of the vehicle flow, vehicle speed and timeoccupancy are exceed 90%.
对车流量、车速、时间占有率这三大重要交通量进行实时检测，准确率达90%以上。

You should, however, fix the nursery size at a large value to minimise time spent in garbage collection, and enable the tenured heap to resize itself according to occupancy to build in resilience.
