As population growth increases, additional demands are placed on existing highway systems. Reconfiguring intersections and roadways to limit the number of access points to a particular roadway reduces congestion and has been shown to increase safety. A GoldSim model was constructed to quantify the environmental benefits due to reduced emissions and the economic impacts on businesses in areas where access management techniques were applied.
The model allows the user to adjust driveway spacing, implement different driveway consolidation strategies and install medians on a segment of highway and view the impact of those changes over time.
