Analytical Approach: Categorization Categorization Prioritization Prioritization Comparative Analysis Comparative Analysis

Analytical Approach: Categorize (FDOT) Categorize (FDOT)  Area Type (Urban, Suburban, Rural)  Number of Lanes (2, 4, 6, 8)  Median Type (Undivided, Divided, Divided-Restricted, 1-Way)

Analytical Approach: Categorization (FDOT Model) Categorization (FDOT Model)  Area Type (Urban, Suburban, Rural)= 3  Number of Lanes (2, 4, 6, 8) = 4  Median Type (Undivided, Divided,= 4 Divided-Restricted, 1-Way) 3 x 4 x 4 = 48!!

Analytical Approach: Other Categorization Tools Other Categorization Tools  Traffic Volume  Speed Classes  Access Management Standards  Terrain (Well, Not in Florida :)  Intersection Configuration  Intersection Traffic Control  Ad Nausea…

Analytical Approach: Prioritization Prioritization  Magnitude of Problem  Crashes  Injuries  Trend  Rate vs. Frequency  What is an Acceptable Crash Rate??
