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.

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
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

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.

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.
