4. SSMs are deterrents; they are additional treatments that can be applied to grade crossings that will reduce the number of grade crossing violations.

5. Aiming at the weakness of traditional evaluation methods, traffic conflict technique and fuzzy synthetic evaluation were introduced into grade crossing safety evaluation.

6. Top speeds of up to 80B110 mph onprimarily shared track (eventually using PTC technology), with advanced grade crossing protection or separation.

7. A bus ran into a train at the level grade crossing.

8. The French ban gradecrossings when train speeds reach 100 mph and enhance grade crossing equipment for corridors with train speeds between 80 and 100 mph.
