VDOT Highway Safety Program: Systemic Improvements Demonstration

Join our Highway Safety Team Staff Meeting to learn about the VDOT HSIP Application and Systemic Safety Improvement projects on November 21, 2017. Explore how Systemic and Spot Highway Safety Projects contribute to safer roadways, with examples of low-cost safety countermeasures. See live demonstrations of the Smart Portal for enhancing highway safety. Visit our demo portals to experience the VDOT HSIP Application firsthand. Discover how to select and implement safety improvements efficiently with our Systemic Tool. Get insights on funding distribution, project evaluation, and more to enhance safety across various roadway types. Contact our VDOT Project Manager for further details and guidance.

  3. Types of HSIP Projects • VDOT Business Plan Action Item 3.2.3 States: • Systemic Highway Safety Project – • A project that consists of a lower-cost/high-benefit highway safety countermeasure that is deployed at multiple higher-risk roadway locations to address a particular crash type. • Systemic projects rarely involve reconstruction of the existing roadway features. • Typical lower-cost safety countermeasures range from $1000 to $100,000 per treated location. • Spot Highway Safety Project – • A project that deploys a safety countermeasure or countermeasures at a single location or along a single corridor on the highway network. • The scope of work often involves reconstruction of existing roadway features or construction of new features such as turn lanes or new travel lanes. • Typical cost to treat a single location is much higher than the individual cost of a single location within a systemic project. • Costs for spot projects can vary widely but are generally in the $100,000 to $10,000,000 range.

  4. Systemic Low Cost Safety Countermeasures Examples: Retroreflective Backplates • High intensity Activated Crosswalk Beacon Flashing Yellow Arrow Ped Refuge Islands • Cost:$20K/intersection • CRF:36 % of left turn angle crashes, 15% of total crashes • Cost:5-7K/intersection • CRF:15 % of all intersection crashes • Cost: HAWK Signal: $90-120K per location • CRF: 29% Total Crashes, 69% Ped Crashes. • Cost: $20-30K/location if no R/W needed • CRF:Ped crash by 46%40-45 % of all crashes FHWA proven safety countermeasure

  5. Systemic Low Cost Safety Countermeasures Examples: Road Diets Rumble Strips/Stripes Curve Delineation Safety Edge • Cost: $20-30K/mile for pavement marking changes • CRF: 29% of all crashes • Cost: $5K/location • CRF: 30-50% of all crashes • Cost:$536-$2,145K per mi • for both sides of the road • CRF: 20%in total crashes. • Cost: $7K/mile – center line RS, $12K/mile – shoulder RS • CRF: 44-64% - center line RS, 36% - shoulder RS FHWA proven safety countermeasure

  8. Guideline and Development The Systemic Tool provides the process and outlines to select systemic safety improvements and projects. The Systemic Tool provides a framework for determining a reasonable funding distribution between spot safety and systemic safety improvements, and discusses the evaluation of systemic safety programs.

VDOT Systemic Application • Focus crash types include: • Angle • Roadway Departure • Rear-End • Sideswipe • Head-On • Bicycle • Pedestrian • The focus facility types include: • Signalized Intersection • Unsignalized intersection • Segment • Curve • Mid-block Select the Systemic Improvement Type Angle Signalized Intersection 5 Years 3 • Risk Factor • Poor visibility of signal • Inadequate signal timing • Excessive speed • Slippery pavement • Inadequate sight distance • Red-light running • Inadequate lighting 50 Inadequate Signal timing Flashing Yellow Arrow 5 Left Turn Crashes in 5 Yrs. • Proposed Systemic Improvement: • Flashing Yellow Arrow • Install additional signal head per approach • Replace 8" signal head with a 12" signal head • Re-time traffic signals for better coordination and for proper red and amber clear intervals • Retroreflective Backplate 40 100 40 40 $ 0 $ 0 $15,000 20 $1,000 $674,877 $600,000 $60,000

  13. VDOT Systemic Application • Applicable Crash Type: • All • Cross median • Fixed object • Head on • Run off road • Angle • Left turn • Right turn • Bicycle • Pedestrian Left Turn 0.7 www.cmfclearinghouse.org Flashing Yellow Arrow $5,302,332 $674,877 7.9 7.9

  14. CMF’s Clearinghouse • Star Quality Rating based on a scale 1 to 5, where 5 indicates the best rating. • We recommend highest star rating and use engineering judgement to select the suitable CMF value. • We are working on developing VA specific CMF value. • CMF should be selected based on the applicable severity and crash type. • CMF should be applied only to the severity/crash type for which they were developed.

  15. VDOT Systemic Application Not Needed $ 0 Not Needed $ 0 Not Started $660,000 2018-10-01 2018-12-01 $660,000 $660,000

  16. VDOT Systemic Application • Location Tab: • Mapping features is linked to VDOT LRS. • Locate the study area where the proposed improvements will be implemented. • Users can add multiple area/systemic sites. • Location is a Required Field.
