Statewide GIS Mapping of Recurring Congestion Corridors
Recurring congestion occurs when travel demand reaches or exceeds the available roadway capacity. This project developed an interactive geographic information system (GIS) map of the recurring congestion corridors (labeled herein as hotspots) in the state of Maryland. The map allows users to obtain images, turning-movement counts, travel times, and roadway schematics for individual hotspots. The GIS map was also converted to a keyhole mark-up list (KML) file so that it can be used in Google Earth's 3-D environment. It is hoped that this study will lead to a statewide mapping of hotspots and help the Maryland State Highway Administration to allocate the resources necessary for the mitigation and management of recurring congestion.
