The relationships between traffic parameters, such as the ramp flow, speed, density and mainline flow at the ramp junction, are established by mapping time-space plane to speed-density plane.

积分后，得到了匝道单车道流量与匝道连接处速度、密度和流量的理论关系模型。

The notion that the speed of thought could be measured, just like the density of a rock, was shocking.

人们可以测量思想的速度，就像测量岩石密度一样，这样的观点确实有点骇人。

When combined, the cache capacity on the drive, the disk algorithms used, the interface speed, and the areal density, produce a disk transfer time.

驱动器上的缓存容量、所使用的硬盘算法、接口速度和磁录密度组合到一起，就构成了磁盘传输时间。

We are hopeful that VelociRFTA will become a model for other communities, similar to ours, which lack metropolitan density, but want urban-like speed, convenience, and efficiency, at an affordable price, in order to address their transit and mobility needs.
