EVERY DAY COUNTS

Launched in October 2010

Designed to:

  • Shorten project

development & delivery

  • Enhance the safety and

performance of our highways and bridges

  • Improve environmental

sustainability

EVERY DAY COUNTS SAFETY INITIATIVES

Pedestrian & Bicycle Safety Intersection Safety Roadway Departure Data Driven Safety Analysis

  • Safety Edge
  • High Friction Surface Treatments
  • Intersection Control Evaluation (ICE)
  • Roundabouts & Mini Roundabouts
  • Restricted Crossing U-Turn Intersection (RCUT)
  • Safe Transportation for Every Pedestrian (STEP)

SAFE TRANSPORTATION FOR EVERY PEDESTRIAN (STEP)

 Road Diets

  • Reduce speeds & No. of lanes
  • Create space for ped. facilities.

 Pedestrian hybrid beacons

  • provide positive stop control

 Pedestrian refuge islands

  • Shorten crossing distance
  • Elderly & limited mobility

pedestrians  Raised crosswalks

  • reduce vehicle speeds.

 Visibility enhancements

  • Detect ped. particularly at

night. Road Diet HAWK Refuge Island Raised Crosswalk Crosswalk Visibility Florida:

  • Institutionalized

INTERSECTION CONTROL EVALUATION (ICE)

Benefits:

  • Consider all available Intersection Controls beyond Traditional Controls
  • Select an optimal control for a specific site and problem.

Florida: Adopted and is in the process formalizing this concept. Resources:

  • Caltrans ICE Policy Directive
  • Minnesota DOT ICE Tech. Memo

RCUT STOP SIGNAL DDI ROUNDABOUT

ROUNDABOUT

Benefits:

  • Reduce conflict points:32 to 8 for

vehicles & 16 to 8 for pedestrians

  • Benefit Cost Ratio as high as 15
  • Reduce Crashes by 70% - 90%

Florida:

  • Intersection Design Guide
  • 3-step screening tool
  • Plans Preparation Manual (PPM)
  • Constructed 22 with 16 in design

RESTRICTED CROSSING U-TURN INTERSECTION (RCUT)

Benefits

  • Reduce conflict points : 32 to 18
  • Reduce Serious Injuries crashes

by 42% to 70%

  • 30% increase in throughput and

40% reduction travel time Florida:

  • Early Phase of the

implementation

SAFETY EDGE

Benefits

  • Simple 30 degrees edge pavement
  • Easy and inexpensive to install
  • Eliminate Edge Drop-off
  • Effective Lane Departure Recovery
  • Pavement edge Density & Stability

Florida

  • Only a few counties
  • “Greenbook”
  • Available shoe at the LTAP center

HIGH FRICTION SURFACE TREATMENT

Benefits

  • Increase friction by 87%
  • High Benefit Cost Ratio of 40
  • Reduce Crashes by 30% to 80%

Florida

  • A Study by Texas A&M Transportation Institute (TTI)
  • HFST Guidelines: Project Selection, Material &

Construction

  • Part of Safety Tool Box w/Specifications - Sec. 333
  • Installed at 57 locations in Florida.

WHY? DATA DRIVEN SAFETY ANALYSIS (DDSA)

DDSA introduces two tools: Predictive analysis:

  • Crash, Frequency, Features & Volume
  • Existing Safety Performance
  • Safety performance of various alternatives
  • Proposed Safety Performance.

Systemic analysis:

  • Severe crash locations are random
  • High-risk features remain consistent
  • Identify high-risk features across a network
  • Low-cost treatment across network.

Benefits:

  • Decision based on safety performance
  • Better Targeted Safety Investments
  • Effectively Reduce Fatalities and Serious

Injuries Florida:

  • Early Stage of integrating DDSA into the

HSIP Program LIMITED RESOURCE
