Abstract:The Louisiana Department of Transportation and Development (LADOTD) is constructing a high-speed, four-lane, rural arterial highway between Interstate 12 and State Route 21 in Bush, Louisiana, to address regional transportation mobility needs and potentially stimulate economic growth and activity in Washington and St. Tammany Parishes. This project will replace an existing two-lane, undivided highway with numerous access points in order to alleviate congestion, shorten travel time and improve safety. LADOTD applied predictive safety analysis to quantify safety performance when comparing proposed alternatives (including the No Build alternative) during the project’s engineering and design phase.
