TRAFFIC ENGINEERING FOR INCREASED MOBILITY AND SAFETY: CENTRAL ARTERY/TUNNEL PROJECT

The Central Artery/Tunnel Project in Boston is the largest and most complex highway project ever undertaken in the core of a major American city. It is funded by the Massachusetts Highway Department (MHD) and the Federal Highway Administration (FHWA), with the MHD being the owner of the project and the FHWA, the co-sponsor. The Central Artery/Tunnel project envisages a reduction of the surface streets from twelve travel lanes to six travel lanes; replacing the elevated highway with an underground expressway. The proposed plan improves the pedestrian flow by reducing the amount of conflict between pedestrians and vehicular traffic. To compensate the loss of travel lanes, an optimized traffic operations plan was necessary. Extensive and detailed models were developed for the Downtown Boston area simulating the traffic flow for the future full build condition.
