I came up with a concept a little while ago. Why don't crossings use rising bollards along with barriers? Would be reasonably costly to install, but would stop cars on the spot. A lot like is used in Manchester for the bus lanes. Would be one way to stop people jumping crossings. Barriers would still be an advantage to stop pedestrians and cyclists ect, who I know can be just as bad, if not worse than motorists.

The main reason we have half barriers is that vehicles can carry on when the barriers have started to come down
If "bollards" were installed vehicles could get "stuck on the crossing.

What about those one way catches often seen at car parks to prevent people driving against them? OK in the correct direction as they lay flat but stay up if you try to drive against them. I think the people who risk getting hit by a train will be more likely not to risk tyre damage. I do not mean the type where a great wide section rises up but the smaller 'finger' type that can be driven over at a reasonably fast speed.

All the suggestions would cost the earth & baring in mind how many level crossings there are some accidents are bound to happen
I will say this again most crossing accidents are caused by miss use.

Ban cars. Problem solved!

Exactly Silver Fox, these days Systems don't just need to be "Fool Proof".......they need to be "Idiot Proof".......

It's so dangerous now, that cost! Is not an option anymore ......

Bring back the manned crossings!.........or, spend the cash for under or over passes at all rail and road junctions!.......

Ban level crossings

one life too many lost through people not thinking hate to be a nanny but if there were no level crossings there would be a few less accidents

On some lines in the Nottinghamshire / Lincolnshire area where the land is FLAT there are a lot of hump back bridges which solve the problem, Over bridges would be better for the railway as they stay on the flat there's nothing for oversized lorries or Double Decker Busses taking the wrong route to hit and close Both Railway and Road.
AND
A bridge building program would give a lot of jobs to out of work people.

Do you know how many level crossings there are between Nottingham & Lincoln alone?
What about the line from Doncaster to Peterborough via Lincoln?

To be honest this is one of those issues where cost SHOULD be irrelevant the Transport people should get their wallets open and DWP should too

Are you saying that a level crossing with a usage of about five cars a day should be bridged?:confused:
There are hundreds of such crossings(low use) through out the railway system.
