I have to agree with most of what has been said when it concerns dealing with most sane human behavior; however what if those who do have mental disorders or learning difficulties are faced with barriers that are less than complete blocks to a crossing, I.e. Half barriers? Do they actually understand the consequences of their actions when the train is coming? We all assume those using a crossing will do so understanding the reasons behind the flashing lights and why the barrier is down. There are other aspects to human behavior other than the plain stupid who risk life and limb to save a few minutes. Just a different view point to this thread.
