Median treatments on arterial roadways for safety and efficiency

摘要

In recent years there has been a steady growth of traffic volumes on urban and suburban arterials in large metropolitan areas in the USA, primarily due to the growth in population and lack of capacity in the existing freeway system. The development of localized shopping centers and other strip commercial and office developments along roadways have created an increased demand for mid-block access. The demand for turning in and out of these roadside strip developments often cause both operational and crash problems.
