INVESTIGATION OF ACCESS POINT DENSITY AND RAISED MEDIANS: CRASH ANALYSIS AND MICRO-SIMULATION

This product provides usable information yielded from researching access management benefits. The product describes the findings of microsimulation 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.
