# What do you mean by time mean speed?

**Time mean speed**( ) As noted earlier,

**time mean speed**is the

**average**of all vehicles passing a point over a duration of

**time**. It is the simple

**average**of spot

**speed**.

Consequently, how do you calculate time with speed?

The **space**-**mean speed** is then calculated by dividing the distance between instrumented locations by the **average** travel **time**. The **time**-**mean speed** is associated with a point over **time**, whereas the **space**-**mean speed** is associated with a section of roadway.

**speed**measured is known as Spot

**Speed**. Journey

**speed**is the distance divided by total journey time. Total journey time includes all delays due to

**traffic**.

**Running speed**is the distance divided by

**running**time, i.e. total journey time minus delays.

Subsequently, one may also ask, what is free speed?

The point C refers to the maximum density kjam and the corresponding flow is zero. OA is the tangent drawn to the parabola at O, and the slope of the line OA gives the **mean free** flow **speed**, ie the **speed** with which a vehicle can travel when there is no flow.

**Traffic flow** shall be calculated by multiplying the **measured** density by the **measured** travel speed.
