Abstract:

This product provides usable information yielded from researching access management benefits. The product describes the findings of micro-simulation performed on real and theoretical corridors. The micro­simulation resulted in impacts that can be anticipated if certain access management techniques are implemented on arterial streets, given certain conditions. In addition, the product provides findings from crash analyses performed on case study corridors in Texas and Oklahoma. The case studies include corridors with and without raised medians, before and after raised median presence, and varying access point densities.
