Chesapeake and Virginia Chapters of ATSSA Meeting October 13th ,2016

Introduction  HSIP is a core program administered at the federal level by US department of Transportation FHWA office of safety.  The primary objective of HSIP :  To identify and improve locations where high concentration or risk of vehicle crashes that result in death or injuries and to implement strategies to attain VA towards Zero death vision.  To make significant progress in reducing highway fatalities and serious injuries on all public roadways.  HSIP project planning and development process have been developed in consultation with FHWA given the MAP-21 Act and FAST Act guidelines final ruling(policy) and funding provided.  FAST Act builds on changes made by MAP-21 provisions to accelerate project delivery and promote innovation.  VDOT’s HSIP consists of the following programs:  Highway Safety Program (HSP)  Bicycle and Pedestrian Safety Program (BPSP)  Highway-Rail Grade Crossing Safety (H-RGCP) 2  Local Agency Safety Program (LASP).

HSIP Implementation Guideline

 HSIP Implementation Process involves:  Identification of High Crash Locations  Analysis of Problems and Countermeasures  Prioritization and Scheduling of Improvement Projects.

 HSIP applications submission and adding safety projects to Virginia Six-year improvement program (SYIP) will only be considered if HSIP Implementation guidelines are followed.  HSIP Implementation Guideline contains High Level discussion on:  HSIP Project Life Cycle.  Highway Safety Program (HSP)  Bicycle and Pedestrian Safety Program (BPSP)  Highway Rail Grade Crossing Safety (H-RGCP)  Local Agency Safety Program (LASP) 6

HSIP Project Tracking Tools

 In house developed project tracking tools.  Tools ensures timely delivery of the HSIP funds and tracks VDOT HSIP projects in a more intuitive and useful way.  Tools help project manager to improve schedule performance.  Contact HSIP staffs for accessing to VDOT tableau project tracking tools.

7

HSP/BPSP Application- Smart Portal  Smart Portal is one-stop-shop for submitting projects applications for various funding programs.  HSIP partners should use Smart Portal for submitting projects applications for HSP and BPSP.  H-RGCP and Systemic Improvement has been scheduled for next year development.  Contact Portal administrator to obtain log-in credentials.

Outside VDOT Resources

 HSIP additional Resources are obtained from OUTSIDE VDOT website – Highway Safety Projects folder.  Contact HSIP Staffs to obtain log-in credentials.

FHWA Preferred Safety Countermeasures

10

Traditional Vs Systemic

 Traditional approaches to safety focused on identifying high crash locations and constructing projects to address predominant concerns at these locations.  Systemic approaches to safety focused on managing safety that typically involves lower unit cost improvement that are widely implemented based on high-risk factors.  Systemic approach to safety is a data-driven process that involves analytical techniques to identify sites for potential safety improvement.  Systemic approaches suggest HSIP projects for safety improvement that are not typically identified through traditional site analysis approach.  MAP-21 places a significant emphasis on Systemic improvement as part of the safety management process.

12

Example Traditional Intersection • Rebuild Intersection  Move curb  Add capacity  Rebuild/replace signal  Some R/W required • Cost: $2-4 Million • Schedule: 2-4 years

• Crash reduction  10-15 crashes/year

Systemic Intersection Deploy flashing yellow arrow at 25 intersections • •

Cost: $500K Schedule: 1 year



Crash Reduction  36% of all left turn angle collisions  90 crashes/year

13

Systemic Projects – Flashing Yellow Arrow

Cost: $20K/intersection Crash Reduction: 36 % of left turn angle crashes Schedule: about a year

14

Systemic Projects – High-Visibility Traffic Signal Backplates

Cost: $7-11K/intersection (much less if doing other work) Crash Reduction: 15% of all intersection crashes 29% of fatal/injury crashes Schedule: less than a year FHWA’s proven safety countermeasure

15

Systemic Projects – Road Diets

Cost: $20-30K/mile for pavement marking changes Crash Reduction: 20-47 % of all crashes particularly rear end, angle, and sideswipe crashes Risk reduction for peds and bikes Schedule: less than a year if coordinated with resurfacing FHWA proven safety countermeasure 16

Systemic Projects –Signal Timing

Elements: • Cycle length, split, Offset, Yellow and Red Clearance intervals, pedestrian clearance interval, pedestrian phase selection. Cost: $5K/intersection

Crash Reduction: 20-33 % of all crashes Schedule: less than a year 17

Systemic Projects – Ped Refuge Islands

Cost: $20-30K/location if no R/W needed Crash Reduction: 40-45 % of all crashes Schedule: 1-2 years

FHWA proven safety countermeasure

18

Systemic Projects – Other Ped/Bike Projects

• Ped countdown Signals $1200/Each • Rectangular Rapid Flashing Beacon $30-40K per location • HAWK Signal $90-120K per location FHWA Proven Safety Countermeasure • High-Visibility Crosswalk $15K/intersection • Green Bike Lanes in conflict areas $20/square foot

19

Systemic Projects – Curve Delineation

Cost: $5K/location Crash Reduction: 30-50% of all crashes Schedule: less than 1 year

FHWA proven safety countermeasure

20

Systemic Projects – Rumble Strips

Cost: $7K/mile – center line RS $12K/mile – shoulder RS Crash Reduction: 44-64% - center line RS 36% - shoulder RS Schedule: less than 1 year
