Accessibility is a critical factor in a state’s quality of life and economic competitiveness. The ability of people and businesses using multiple transportation modes to access employment, customers, commerce, recreation, education and healthcare in a timely fashion is critical for the development of a region and a state. Maryland’s quality of life and economic development is being hampered by high levels of traffic congestion and reduced accessibility, but stands to benefit from a statewide program to improve accessibility in the Old Line State and could realize significant benefits from a proposal for an even more robust program to improve mobility. TRIP’s “Keeping Maryland Mobile” report examines the mobility and efficiency of the state’s transportation system and improvements needed to enhance access.
