Why Consider a Road Diet? -- Case Studies New York City – Advantages & Disadvantages District of Columbia – East Street Tampa, FL – Nebraska Avenue 9 Enhanced SAFETY for ALL ROAD USERS LOW COST and LOW IMPACT Improved MOBILITY and ACCESS for all modes “COMPLETE STREETS” characteristics
10
New York City Road Diets 10 Pedestrian and Bicyclist Benefits Improved MOBILITY and ACCESS for all modes
11
Road Diet Advantages -- NYC Improved safety and mobility for cyclists and pedestrians Reduction in fastest speeds Crash reduction
12
Road Diet Disadvantages -- NYC Increased travel delay Increased delay on side streets Loss of passing opportunities
13
District of Columbia Road Diets 13 “COMPLETE STREETS” characteristics Livabililty and Complete Streets
14
Goals for DC Road Diets so far Create space for bike lanes Improve ‘livability’ Increase pedestrian safety 14

Nebraska Avenue – Summary Results 38 Reduction in crashes per year Improved pedestrian safety Reduction in key crash types – Sideswipe – Left Turn/Angle – Head on Crash Rate is less than the statewide average for 2-lane divided roadways (Previously 50% higher than the 4-lane undivided average). Favorably compares to the FHWA estimated reduction of 29%- 53% (Desktop Reference for Crash Reduction Factors) 59% reduction in crashes, 51% reduction in crashes per MVMT
