2 What When Why How Who

3 What When Master Data Set Why How Who

4 What is it all about? ARNOLD Per the FHWA, State DOTs are required to provide an LRS Network for All Public Non Federal Owned Highways only by June 15, 2014

5 Why

6 Working Together Saves money $$$ It s the right thing to do

7 Examples of LBRS Users ODOT/ OGRIP Federal State County Local Department of Homeland Security Highway Patrol/MARCS Dispatch First Responders Townships Census Bureau Department of Natural Resources Auditors Cities Department of Agriculture Engineers Villages Ohio Utilities Protection Service Commissioners Emergency Management Agencies GIS

8 Why Data must be integrated at the local level Accurate Topology Road name Mileposts Linear references

9 LBRS Map Services Too much was not enough! In 2001 Ohio suffered from an abundance of data developed for specific business needs with little regard for interoperability, standards, maintenance, or authoritative sourcing. State agencies could pick from data developed by the: State DOT U.S. DOT Department of Census / TIGER Local Governments Vendor Community Address level data was virtually non-existent. Positional Accuracy 1994 Image Data Sources

10 Why Red dots represent Un-Posted Addresses SR-103 Interpolated SR-103 SR-103 SR-103 Field Verified SR-103

11 Road Attributes Local/county engineer identifier 911 and most other databases GPS coordinates Situs address Address Attributes 911 Community Field (specific & necessary for 911) DOT identifier Address location via LRS

12 LBRS Map Services Too much was not enough! Spatially accurate statewide road centerline data +/- 1 M Horizontal Verified Address ranges Site specific field verified address locations Higher confidence/increase reliability for geocoding Known accuracy & limits of data and use One set of geography Multiple attributes for different uses at all levels of government Locally maintained collaboratively funded

13 Clark County 4,383 crashes Before 24% (1,064) locatable 76% (3,319) un-locatable After 70% (3,061) locatable 30% (1,322) un-locatable

14 Located using existing road inventory data Additional Crashes located using improved road inventory data with house number and intersection information

15 ODOT Crash Data Analysis Study locate crash locations using three different models Street file from a leading national map data provider Street file DDTI collected for LBRS Street and address file DDTI collected for LBRS 2006 Clark County crash data test set (817 crashes) 709 city or village crashes 108 township crashes Model Used Township City Total National Data Provider 61 of % 450 of % 501 of % LBRS Street 72 of % 675 of % 747 of % LBRS Street & Address 87 of % 687 of % 774 of % Source: Ohio Department of Transportation

16 Benefits 1. Saving tax payers dollars 2. Ability to have locational method that the public understands 3. Beneficial to the departments safety program 4. Higher confidence in the validity of the data Locally Maintained.

19 How? Master Data Set GIS 911 Engineers City Officials Local Addressing Authorities

20 NG9-1-1 will enhance emergency response communications IP-based communication network between the public and Public Service Answering Points (PSAPs) In addition to voice calls, PSAPs will be able to receive and process text, video, telematics, images and other digital data

21 Geospatial Databases are key to NG9-1-1 functionality No longer for display purposes only, emergency calls will be routed using GIS data (ECRF/LVF) Road centerlines, address locations and jurisdictional boundaries must be accurate Ongoing maintenance is needed to keep information up to date Inter- and intra-agency collaboration will encourage GIS data sharing and coordination

22 Who better to help than 9-1-1? If isn t collecting data already, they will be!

23 Collaboration is key!

24 Working Together Saves money $$$ It s the right thing to do

25 Ohio had to coordinate a large initiative to get everyone on the same page. 911 has allowed the state of Ohio to make this happen.

26 Ohio has the nation s: 6 th largest highway network 2 nd largest inventory of bridges 5 th largest volume of traffic Ohio has over 123k road miles (we rank 7 th in the nation)

27 Ohio has 88 counties 1,300+ townships 730+ cities 11mm people

28 Collaboration is key! We had the foresight to engage We took the initiative and knew working with was the right thing to do! Ohio is already ARNOLD compliant closer cooperation between NHTSA & FHWA

29 Bridge the gap 911 DOT

30 You can do it!

31 Creating Master Data Sets Build it once, use it a bunch Questions?

32 Master Data Set Create it once, use it a bunch The DOT gets what they want & Local Entities get what they need The data is locally maintained It s a Win Win!
