Why speed bumps at the exit?

If you place it after the boom / barrier you may interfere with the drivers ability to pick up speed to join the traffic. That may create accidents.

The speed bump before the boom also seems like a waste. Normal people will in any case slow down.

For abnormal people you can place a notice "Speedster you are still alive because it is illegal to shoot you"

If you have speed humps, they should always be placed in front of the barrier, as traffic flows.

I tend to agree with Hendrik. Depending on the size and layout of your lot, they may do more good in the interior than at the entry/exit.

If there is a barrier why the heck do you need a bump...? Presumably the car has to stop for the barrier.
maybe a bump before the bump to stop the cars hitting the bump too fast
What exactly is the purpose of the bump?
Involuntary urination is common enough without encouragement

U r bump right. the bump is required to stop the cars hitting the bump too fast. otherwise you will replace your bump very often....

to all of you guys, thanks for the encouraging as well as amusing contributions...

all the best,

Have you considered inflatable speedbumps that look like concrete speed bumps?

Where do you want people to slow down?

Is a car park, the same as a parking lot?

Hello jackychang777,

I am wondering if you are a professional car park builder? Where ever you are, if you are building the park for the 'public', then local 'by-laws' and 'reg's' will dictate where or if there should be humps anyway. If you are building for a private customer, say under a tower block for instance, then I can see that a hump every 50 metres would help stop any 'fun and games like racing?

I think you may find that humps are used to slow traffic as it comes to a 'junction' in the car park.

Very odd asking questions like this when you are a builder of car parks though? I would have thought you would have this info' to hand before you started, or it would be on the plans?

Hi BB,

you find it odd because unfortunately, u did not get the point.

when i say controlled car park, i mean like those paid car parks where cards are used to enter and exit from the car park. there are cases when a parker who tries to evade payment of fee will simply "tailgate" an exiting vehicle and beat the lowering of the boom/barrier. this leads to likely hitting the boom/barrier.

therefore, there is a need to slow down the first exiting car or slow down the "tailgating" car to avoid such situation.

in a nutshell, the humps being referred to are meant to protect the boom/barrier.

if it were in the plan, i won't ask about it.

thanks.

Hello jackychang777,

You are right, I did not 'get' the question in the first place. But I did not mean to insult you, OK?

Take care

In the situation you describe, I would try to space the speed humps close enough that an exiting car would have to ride over a series of humps. Close enough that speed would need to be slow, accompanied by turn that would not allow tailgating. Space the humps so that they are not able to hit front and rear tires at the same time. That will slow the cars well. Instead of a timer on the gate, use an electric eye to drop the gate after the first car. Make the gate appear to me more substantial. If they fear the gate, they will not want it to hit their car.

The sort of people who would try to avoid payment are the same sort of people that would try to catch some air going over the speed bumps just for fun. Double gating or video systems with a legal authority to issue citations would demonstrate a determination to stop the problem. Too expensive you say. If your losses aren't considered sufficient to justify installing a serious system, don't waste your time on bumps.

You could follow the designs of the idiots in my town and put them everywhere. For example, at a popular natural foods market here, there are three humps in the entrance drive that are so close together that a crew-cab long-bed pick-up truck can almost hit the second one while still on the first one.

Also, don't forget your streets either, you need them placed in frequent spacings there as well.

I agree with 'Guest' regarding placement in the lower intestinal tract.

I think it really depends on the size of the lot....but I don't see a reason why you would put them at the exit and not anywhere else.
