Research will be conducted on counter measures by incident and grade crossing type that have been implemented and successfully reduced crashes and incidents at grade crossings throughout the country. Working with the NJ TRANSIT Planning and Engineering Departments, a list and map of grade crossings that are used by NJ TRANSIT will be provided to support this work. Statistical and other safety data provided by NJ TRANSIT will be used to determine the number and type of crashes or incidents at each grade crossing in the last five years to help prioritize improvements. Using the research data, recommendations for countermeasures will be made for the top 20 grade crossings with the highest number of incidents. Concept plans and cost estimates will be prepared for each crossing.
