There are no specific way to calculate length of acceleration lane (LA). Even AASHTO 2004 Green book also only include tables to predict minimum LA. However, from Highway Capacity Manual 2000 (exhibit 25-5) shows calculation to get flowrate in lane 1 and lane 2. In the equation exists LA variables. Therefore, if you can know value of freeway demand flowrate (in pcu/hr) and flowrate in lane 1 and lane 2, then i guess you can get the answer for LA
You must calculate the change in velocity during each unit of time.
(any unit of length or distance) divided by (any unit of time)2 is a unit of acceleration.
The answer depends on whether the graph is that of speed v time or distance v time.
time
(any unit of speed) / (any unit of time)OR(any unit of length or distance) / (any unit of time, squared)is a perfectly appropriate unit of acceleration.If you're dealing with acceleration as a vector, then a direction also needs to go with it.

To calculate the acceleration of gravity, time (t) an object falling a certain distance (d) and the acceleration of gravity= d/t
No. That's only one of several possibilities. -- with initial velocity, distance, and time, you can calculate acceleration -- with final velocity, distance, and time, you can calculate acceleration -- with force and mass, you can calculate acceleration -- with initial and final momentum, you can calculate acceleration -- with initial and final kinetic energy, you can calculate acceleration -- with mass, velocity at either end, and kinetic energy at the other end, you can calculate acceleration And I'm sure there are several more that I've missed.
how do you calculate the acceleration of a moving object.

Acceleration = (change in speed) divided by (time interval)
The period (time) of one swing of a pendulum is(2 pi) times the square root of (pendulum length / acceleration of gravity). There are three variables in this formula ... the length of the pendulum, the period of itsswing, and the acceleration of gravity. If you know any two of them, you can calculate thethird one. You want to use this method to measure gravity ? Fine ! Massage the formulaaround to this form Acceleration of gravity = (length of the pendulum) times (2 pi/period)2 then start measuring and swinging.The more accurately you can measure the length of your pendulum, from the pivotto the center of mass of everything that swings, and the period of its swing, and themore completely you can isolate everything from outside influences, like air currents,the more accurately you can calculate the acceleration of gravity, in the exact place whereyou run the experiment.

When entering an expressway, never stop in the acceleration lane unless traffic is stopped. This would cause an accident if the traffic was not moving and a persons car was continuing to accelerate.
you can caculate the acceleration of a commercial airplane when the airplane slows down
Average acceleration = Change in speed/time so Time = Change in speed/Average acceleration
