In recent years, transportation agencies have increased construction of raised medians on urban and suburban arterials. With respect to access control, raised medians restrict left turns to midblock and intersection median openings. While improving the operations and arterial signal coordination, the economic impacts of restricting these left turns may be felt by owners of businesses and properties adjacent to the arterial. This paper describes the research to date in the third year of a 4-year study to evaluate the economic impact of raised medians. The primary purpose of the project is the development of a methodology to determine if there are any economic impacts on adjacent businesses when a raised median is installed. In the first year, researchers developed a methodology and tested it on a case study in College Station, Texas. After analyzing the procedures and results of that test, they revised the methodology and tested it on 10 case studies in six other Texas cities during the second year. The third year is being used to analyze the data collected in the additional case study locations and to collect additional data. The final year will be used to collect postconstruction data along two corridors and complete all analyses. The current methodology, consisting of eight main steps, provides a logical structure by which the user can identify case studies, collect data, and analyze data: identify sites with potential corridors, identify corridor characteristics, contact sources of information, inventory businesses and establishments along the subject corridor, obtain information about businesses, prioritize businesses to be surveyed, collect data by personal interviews, and analyze and summarize data.
