SPR-4736: A Study of Suburban Arterial Safety Performance Based on Median Type

There is a need for guidance on selecting a proper median type when planning significant work on suburban arterial roadways to properly balance their safety and accessibility. This guidance will be based on the density of local land use, needs for access, traffic volumes, and desired speed limit. Equations, tables, and graphs, whichever most appropriate, will be provided to decide between a two-way left-turn lane and a continuous median with openings and their design.
