Improving access management strategies has not only safety benefits in the order of millions annually, it has system performance benefits – travel time reliability – as a function of gross state product value – the movement/cost of the goods and services and the economic performance of industry in your state.  The cost of the supply chain – and the competitiveness of the products of your state competing against others in global trade.

FHWA/Safety/Intersection/Intersection Safety

Imagine a multilane urban/suburban roadway where traffic is heavy, yet moves well; accommodates drivers, pedestrians, and bicyclists; allows easy entry to and exit from businesses and other destinations; and has fewer crashes and other conflicts. Chances are this road is benefitting from corridor access management, a strategy that seeks an appropriate balance between the safety and mobility of a roadway facility with the access needs of adjacent land uses.

The purpose of this study was to determine whether acquiring additional limited access right-of-way (ROW) at the time an interchange is built and before the surrounding area is subdivided and developed, is in fact cost effective in light of potential costs and benefits. The study methodology included the following: (1) traffic operations analysis of the interchange with varying configurations of signalized access spacing, (2) safety analysis of interchanges with varied access spacing in Florida, and (3) a cost/benefit analysis of acquiring varying amounts of limited access ROW.
