Aside from the outrageous costs at a time of deficits , the real point is that if our society is so degraded that no one will assist the blind at traffic crossings , it is beyond the government 's ability to fix . As part of a major experiment to be announced today , computers emulating the human brain will monitor the level crossings , deciding when it is safe to lower and raise gates , and when cars and pedestrians should be allowed to pass through . The primary focus of the program is to elevate the importance of public awareness regarding the potential hazards at rail-highway grade crossings , and the dangers of trespassing on railroad right-of-way . In reviewing permit applications required for road or railroad crossings , consideration shall be given to crossings with or adjacent to existing facilities , such as roads and utilities . Underpasses , special fencing at traditional wildlife crossings , and warning devices placed directly on automobiles can reduce collisions . Since rules prohibit speeds in excess of 79 miles per hour where there are grade crossings , you can calculate the amount of approach track needed if you know how much advance warning you need ( someone who got on the tracks as the gate closed behind him needs time to get off before getting hit by the train ) . The park will receive nearly $ 900,000 to make improvements to the railroad including the upgrade of railroad signals at grade crossings , and for the purchase of a railroad maintenance vehicle and an Americans with Disability Act accessible railcar . The Office of R & D has conducted outreach meetings with constituent groups to discuss projects in the areas of human factors , grade crossings , hazardous materials , track , equipment , and train control matters . From a safety perspective , the project resulted in the elimination of numerous rail-highway grade crossings , thereby significantly enhancing safety for the motoring public and also contributing to more fluid movement of trains .
