Presentation Transcript

  1. Purpose “…to evaluate existing pedestrian crosswalks and determine if additional countermeasures are needed to facilitate a safe and convenient pedestrian crossing of S. Atlantic Avenue (CR A1A).”

  2. Project Limits

  3. Project Limits

  4. Looking north at Sea Woods Blvd

  5. Looking north from 17thAv

  6. Looking south from 12thAv

  7. AADT and LOS Comparison for S. Atlantic Av

  8. Marked Crosswalk Inventory

  9. Looking south at mid-block crossing between 6th Av and 7th Av

  10. Looking west at mid-block crossing between 6th Av and 7th Av

  11. 8-Hour Pedestrian/Bike Volumes Crossing S. Atlantic Av

  12. Crash Summary Over 42 month period: • 66 total crashes • 1 fatality • 19 crashes with injuries (23 injuries) • 6 pedestrian/bicycle/motorcycle crashes • 53 daytime crashes, 13 nighttime crashes • 59 crashes with dry conditions, 7 crashes with wet conditions

  13. 42-Month Crash Analysis

  14. Vehicle Gap Size Analysis Minimum gap required for safe pedestrian crossing at 20th Street(5 lanes/60 feet) – 27 seconds “…pedestrians would have enough gaps to cross one direction at a time, but not both the directions in one stretch.”

  15. Qualitative Assessment • With 14 marked crosswalks within the 3.05 mile project length, the spacing between them averages 1,240 ft • Sidewalks are not continuous throughout the project limits • Horizontal curve between 5th Av and 6th Av limits sight distance • Ponding occurs on crosswalks after rains • No paved shoulders from 27th Av to 7th Av; bicyclists and motorists must share lane or use sidewalk • 85th percentile speeds: 50 mph from city limit to 27th Av and 48 mph from 27th Av to 3rd Av • From observations in the field (and from gap study), it appears difficult for pedestrians to cross the 5-lane section • None of the existing mid-block crosswalks showed sufficient pedestrian crossing volume to warrant a mid-block crosswalk

  16. Beneficial Measures • Install continuous bicycle facilities along S. Atlantic Avenue • 4’ Paved Shoulders • 5’ Paved Shoulders • Install sidewalk along the east side of S. Atlantic Avenue between 27th Avenue and 7th Avenue • Install Rectangular Rapid Flashing Beacons (RRFBs) • Supply Pedestrian Flags • Install Median Refuge Islands • Install Advance Yield Markings with Signs • Install Additional Marked Crosswalks at Intersections • Install On-Street Parking • Reduce Vehicular Travel Speed

  17. Comparison of Beneficial Measures

  18. Summary of Crosswalk Measures
