4 Focus Area Purpose/Scope Strategic Plan Vision: Safe, smooth, and quiet pavements. Mission To provide insight and applications that assist FHWA leadership in assuring that pavement surfaces meet and/or exceed our client s expectations. Scope The SC FALCON Team will provide a multi-year strategic plan that coordinates the activities within FHWA that are concentrated in delivering an effective pavement surface characteristics program.

5 FHWA Strategic Plan National Performance Objectives 4.1 Smoothness Pavements are designed, constructed and maintained to meet users expectations relative to ride quality. 4.2 Friction Pavements are designed, constructed and maintained to reduce friction-related crashes. 4.3 Noise Highway agencies use quiet pavement systems in noise-sensitive areas. 4.4 Splash and Spray Pavements are designed, constructed and maintained to reduce the potential for splash and spray.

6 Performance Measures Strategic Plan 4.1 Smoothness Good Ride Quality Percent of VMT on NHS with IRI less than 95 in/mi. - From HPMS Acceptable Ride Quality Percent of VMT on NHS with IRI less than 170 in/mi. - From HPMS

7 2007 Pavement Condition on the National Highway System (NHS) National Average = 56.7%, Target 57% in 2009 Good/Very Good (IRI of <95 /mile) > National Average > 1-10% below National Average > 10% below National Average 37.4% CA 70.5% OR 59.6% WA 65.9% NV 64.7% ID 53.5% UT 80.8% MT 66.8% WY 81.9% AZ 83.7% NM 45.5% CO 65.5% ND 62.0% SD 50.1% NE 79.6% KS 59.4% OK 57.0% MN 48.2% IA 73.2% MO 61.9% AR 48.6% WI 33.4% IL 62.5% IN 45.0% MI 84.1% TN 68.5% KY 76.5% OH 52.0% PA 69.4% WV 56.7% VA 67.8% SC 74.5% VT 57.7% NC 35.0% NY 69.1% NH 69.9% MD 66.2% ME 20.6% NJ 0.0% DC 74.2% MA 55.2% DE 51.0% RI 46.9% CT 43.6% TX 46.2% LA 59.9% MS 82.1% AL 94.2% GA 92.0% FL 53.1% AK 14.3% HI 3.1% PR Source: HPMS Compiled By: Office of Pavement Technology Federal Highway Administration March 2008

8 Performance Measures Strategic Plan 4.2 Friction Friction Improvement Consideration Factor Extent to which highway agencies consider friction in the pavement design, construction, management, and maintenance processes. - Rating by agency (self assessment) - Number of Agencies Friction Related Crash Rate Friction-related crash rate (related to wet-weather and pavement). - Number of agencies - Extent of National Highway Network

9 Performance Measures Strategic Plan 4.3 Noise Quiet Pavement System Consideration Factor Extent to which highway agencies consider quiet pavement systems in the pavement design, construction, management, and maintenance processes for noise-sensitive areas. Quiet pavement systems (initially defined by states in the self-assessments) Noise-sensitive areas (defined by states in the self-assessments)

10 Performance Measures Strategic Plan 4.4 Splash and Spray Splash/Spray Consideration Factor Extent to which highway agencies consider splash and spray in the pavement design, construction, management, and maintenance processes. - Rating by agency (self assessment) - Number of Agencies Rutting Condition Average rutting depth per sample unit. - From HPMS

11 National Strategies Strategic Plan Develop, promote, and deploy assessment capabilities and technologies to improve highway systems. Demonstrate the benefits of using pavement surface characteristics as a highway system performance indicator. Develop and implement policy guidance to align with quality assurance, environmental policy, and safety policy. Develop a national management program.

22 ProVAL 3.0 The Graphical User Interface (GUI) of ProVAL 3.0 is completely redesigned ProVAL 3.0 is very intuitive and easy-touse ProVAL 3.0 includes a lot of powerful new features It takes the profile viewing and analysis experiences to the next level

23 Files import and profiles selection Powerful viewing options Manage profile data using thumb nails Easy access of analyses

24 Powerful chart controls Better Input settings management Grinding strategy management Better reports and charting

25 Features ProVAL 2.7 ProVAL File and Project Management Separated project analysis file (*.pv2) and imported data files (*.ppf) are used to store analysis settings and profile data, respectively. An all-in-one single compressed file (*.pv3) is used to combine all imported profile data and analysis settings while imported data can be exported. 2 Sections Handling The features of point reset and/or cropping tools facilities are used to define and handle a single section of interest. Can only use lead-in and lead-out to define one section of interest. Sections facility in the Editor can be used to define multiple sections of various categories (e.g. generic, exclusions). Therefore, lead-in and lead-outs can be handled more gracefully. 3 Ride Statistics Separated modules are used for Ride Stats, Ride Stats at Interval, and Ride Stats Continuous analyses. A limit of one file to be analyzed is imposed in the latter two analysis modules. A single Ride Quality module is used to provide all three types of ride quality analyses. Also, multiple files are allowed to be analyzed for all three analysis types. 4 Input Settings Input set is used to handle input settings. An improved analysis template is used to manage input settings. 5 File selection Users need to manually select files for analysis. Only limited numbers of files are allowed. A file selector facility is used to speed up files and profiles selection. No limitation on number of file selections! 6 Milepost Display Mileposts can only be in increasing manner. Allow display of profile charts in terms of mileposts and in proper increasing or decreasing manner. 7 Charts Limited functions for chart controls. No charts for fixed interval reports and histograms. Now all charts come with zooming, scrolling, panning, and zoom history support. Charts also are added for fixed interval reports and histograms. Grinding charts are added to highlight grinding locations. 8 Report Save reports in HTML format. Generate reports in secured PDF format.
