4 Goals of this Webinar Once you have completed this webinar, you will: Have an understanding of the U.S. Road Assessment Program (usrap) including the core protocols and how these apply to improving safety on rural roadways.

5 Learning Outcomes To achieve the webinar goal, you will learn to: Identify usrap s function and unique value in safety analysis Understand the application of the ViDA software in generating star ratings & safer road investment plans Use the ViDA software through a demonstration Pursue a usrap project in order to meet data-driven safety analysis needs in rural areas 5

6 Bruce Hamilton, Roadway Safety Foundation Identify usrap s function and unique value in safety analysis Understand the application of the ViDA software in generating star ratings & safer road investment plans Use the ViDA software through a demonstration Pursue a usrap project in order to meet data-driven safety analysis needs in rural areas 6

7 usrap Objectives Focus on reducing risk of fatal and serious injury crashes Assure that highway safety improvement programs are based on rational assessment of risk

8 usrap Objectives Work cooperatively with highway agencies Benchmark safety of road segments Allocate resources based on risks Infrastructure Enforcement Inform and provide guidance to motorists Foster collaboration

9 usrap established in 2004 by the AAA Foundation for Traffic Safety Modeled on successful EuroRAP and AusRAP programs

10 ROAD ASSESSMENT PROGRAMS EuroRAP AusRAP usrap irap

11 irap is a not-for-profit organization based in the U.K. irap was established in 2005 to help coordinate the EuroRAP, AusRAP, and usrap programs irap also took on a mission to apply RAP protocols in low- and middle-income countries RAP programs are now active in over 70 countries irap Global Technical Committee (GTC) assures technical quality of RAP protocols and tools

12 usrap Sponsor Roadway Safety Foundation 501c3 in Washington, DC dedicated to promoting road design improvements, safe roadsides, and enhanced operating conditions Through cooperative agreement with Federal Highway Administration, promotes usrap as appropriate tool for data-driven safety analysis in Every Day Counts 3 Contact: Bruce Hamilton (brucehamilton@roadwaysafety.org)

13 usrap and Rural Roads irap vision: A World Free of High-Risk Roads Engineering/design vital in Toward Zero Deaths/Vision Zero efforts Not all E s created equal Can t educate our way to Zero: Ambitious goals call for ambitious plans We need to design out risk & create cultural shift

14 usrap and Rural Roads State DOTs have solid crash data, but locals often don t And 75% of the nation s road mileage is under local control! usrap can be used anywhere, but is an especially value-added resource where: Crash data is lacking or unreliable (often local/rural) Hazard potential is high (2-lane rural highways) VMT is so low that the truly risky design of a road doesn t become evident in crash patterns (rural)

18 usrap Protocols Risk Mapping Performance Tracking Star Ratings Safer Roads Investment Plans NOTE: All based on fatal and serious injury crashes

19 What is a Safer Roads Investment Plan? Safer Road Investment Plan: A plan that suggests specific safety improvements at specific locations on a selected roadway network Input Data: Approximately 50 roadway and traffic characteristics for each 300-ft (100-m) segment of the roadway network Processing Software: web-based ViDA software Output: a safety improvement plan for your road network 19

20 What Does a Safer Roads Investment Plan Include? Safer roads investment plan for a road network includes: Specific countermeasures to be implemented Specific implementation locations Quantitative cost estimates Quantitative safety benefits (in crashes reduced and dollars) Cost-effectiveness measures Benefit-cost ratios All countermeasures meet a minimum benefit-cost ratio specified by the user Output in the form of tables, maps, and Excel spreadsheets

21 How Can a Safer Roads Investment Plan Help Your Agency? Plan focuses attention of the priority locations for safety improvement on your road system and the appropriate type of safety improvement(s) for each location Requires a 30-minute investment in input data coding per mile of road All results are based on benefit-cost analysis only improvements that meet a minimum benefitcost ratio that you specify are suggested

22 ViDA Software Performs network-level safety planning analysis to provide a safer roads investment plan Web-based and easily accessed on-line Free software use for all highway agencies and their consultants Uploads and processes input data for most roadway systems within a few minutes Displays results on-screen and in downloadable Microsoft Excel files No detailed site-specific crash data needed Network-wide crash data is useful for calibration

23 Who Can Benefit Most from Safer Roads Investment Plans? Highway agencies without good crash data No crash data available Manual crash reports but no automated data files Automated crash data files, but no location data other than verbal descriptions Highway agencies without good crash analysis systems Highway agencies with good road inventory data Highway agencies with video coverage of its road system In the age of Google Street View and Bing Streetside, that s almost everyone

24 usrap Analysis Process Coded Roadway Attribute Data Road Safety Scores Star Ratings Safer Road Investment Plans

25 STAR RATINGS

26 Star Ratings Star ratings have been used since the inception of RAP programs Star ratings are assigned based on presence or absence of road design and traffic control features related to safety Over 50 safety-related design and traffic control features are considered Star ratings are in 1 to 5 scale: 5-star road (full range of known safety-related design and traffic control features) 1-star road (limited safety-related design and traffic control features)

27 Star Ratings Separate star ratings by user type: Vehicle occupants Motorcyclists Pedestrians Bicyclists

28 Key Safety-Related Roadway Characteristics No. of lanes One-way/two-way Roadway width/lane width Shoulder width Horizontal alignment (esp. curve radius) Vertical alignment (esp. grades) Delineation Road surface condition Sidewalks

29 Key Safety-Related Roadway Characteristics Roadside severity Shoulder rumble strips Access point density Median type Intersection type Pedestrian facilities Bike facilities Area type (rural/semi-urban/urban) Land use (commercial/residential)

30 Key Safety-Related Roadway Characteristics Quality of curve Quality of intersection Quality of pedestrian crossing

31 Key Operational and Traffic Control Characteristics Traffic volume Motorcycle percentage Pedestrian flow Bicycle flow Intersecting road volume Speed limit 85 th percentile traffic speed

42 SAFER ROADS INVESTMENT PLANS

43 Safer Roads Investment Plans Site-specific plan for cost-effective safety improvements Includes safety improvements for an entire road network Developed from same database as star ratings Based on road attributes without the need for detailed site-specific crash data Network-wide crash data can be used for calibration No other comparable tool is available

44 Safer Roads Investment Plans Considers over 70 countermeasures Each countermeasure is reviewed for each 300- ft (100-m) road segment. A countermeasure is triggered if it makes engineering sense for the location Once a countermeasure is triggered economic analysis is performed

45 Safer Roads Investment Plans Countermeasures are incorporated in the plan for a given 300-ft (100 m) road segment if: countermeasure is not already installed BCR exceeds minimum BCR specified by the user countermeasure is compatible with other costeffective countermeasures for the same location countermeasure is not overridden by a mutually exclusive countermeasure for the same location that is more cost-effective countermeasure is consistent with countermeasures recommended for adjacent road segments

46 Safer Roads Investment Plans All analyses are based on consideration of fatalities and serious injuries Serious injuries are defined as Levels 3 through 5 on the Maximum Abbreviated Injury Scale (MAIS) corresponds to A injuries and all or most B injuries on the KABCO scale Ratio of serious injuries to fatalities can be based on actual crash data, where available

47 Safer Roads Investment Plans User provides data or best available estimate for network-wide average fatalities per year Program logic decides how to allocate those crashes to the various road segments on the network Results can be reviewed/verified with download file
