Visualizing Road Network Congestion to Inform Regional Planning in Southern Maine

In this analysis, road traffic volumes and capacity estimates are used in conjunction with population data and population change forecasts to visualize the potential for congestion at present, and to project the potential for congestion in 2030. The areas most and least at risk of congestion are identified, so as to inform thought and effort around planning on a regional scale in southern Maine. The area of study includes large portions of York and Cumberland Counties, as well as a small portion of Androscoggin County, in the Greater Portland region
