Highway Safety Improvement Tracy Turpin, PE. Highway Safety Improvement Program Manager Virginia Department of Transportation Presented at Chesapeake and Virginia Chapters of ATSSA Meeting October 13 th,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) Local Agency Safety Program (LASP). 2

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. https://smartportal.virginiahb2.org/#/ 8
Outside VDOT Resources HSIP additional Resources are obtained from OUTSIDE VDOT website Highway Safety Projects folder. Contact HSIP Staffs to obtain log-in credentials. 9
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 Systemic Intersection Rebuild Intersection Move curb Add capacity Rebuild/replace signal Some R/W required Deploy flashing yellow arrow at 25 intersections Cost: $500K Schedule: 1 year Cost: $2-4 Million Schedule: 2-4 years Crash reduction 10-15 crashes/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 FHWA proven safety countermeasure 21
