NNEPRA plans to increase train service frequency between Boston & Portland.The team analyzed train consist, speed, frequency, train horn near crossing.Until recently, the team had to count structures from aerial maps.Instead they used GIS analyses to determine the screening distance and multiple buffers within ArcGIS were developed.GIS analysts performed spatial analyses to determine how many homes would be impacted.This refined approach resulted in significant cut to overall project cost & time
