Low Jerk Throttle & Brake Controllers for Public Buses

Some railroad reg. requires a passenger train to decelerate with a
jerk < 2 m/sec^3.  Don't how or even if they do it on trains but it's
a good idea to keep the jerk down when passengers are out of their
seats and walking to an exit.

It could be done automatically on public buses to reduce tumbling down
the aisle incidents.  It would also reduce the multi tasking load on
bus drivers trying to pull out into heavy traffic before passengers
are seated..

The brake pedal would have an override, i.e., stomping all the way
down, in case a pedestrian stepped out in front of the bus.

The number of elderly will soar along with fuel prices so this will
save a lot of lives.

As a Senior Citizen who in-spite of a Berg Balance Score in low-mid 
20's actually can walk with 2 canes

*NO* !!!!!!!!!!!!!!!!!!!!!!!

I do not believe you have:
  1. observed the problem set in the field
  2. correctly identified the actual condition of maximum hazard
  3. considered "Law of Unintended Consequences"

That conjours up an image of someone being rated for how well they balance
on a large block of ice floating on flowing water.

Gee, that was almost interesting.

How about a minuscule flake of ice ;/

OP had not done homework.

sounds dangerous. trains don't have to deal with other traffic.

you should try this on a simulator, perhaps the TORCS software could be
modified to emulate with your constraints.

There has to be a reason why you've posted this on alt.g-w, surely?

He doesn't feel like he exists if someone is not giving him sh*t about
his ideas.  Plenty of that being flung in alt.g-w.

IMHO, the location of the jerk is the driver's seat, so that's where
you want to be removing the problem.

A bus can operate at up to 200 passenger miles / gallon.
