Big Data
• Big data is a collection of large data sets so large and complex that it becomes difficult to process using on-hand database management tools. More data tends to lead to more accuracy. More accurate analyses may lead to more confident decision making. And better decisions can mean greater operational efficiencies, cost reductions and reduced risk.
The four dimensions of use Aspects of the way in which users want to interact with
their data…
Totality: Users have an increased desire to process and analyze all available data
Exploration: Users apply analytic approaches where the schema is defined in response to the nature of the query
Frequency: Users have a desire to increase the rate of analysis in order to generate more accurate and timely business intelligence
Dependency: Users’ need to balance investment in existing technologies and skills with the adoption of new techniques

ODOT Count Program
Where do we (ODOT) collect traffic data? 3 – Year Cycle
– State System Roads (Interstate, US, and State Routes)– 14,200
6-Year Cycle (Local Roads)
– HPMS Universe Counts – 4,200– Safety – 3,700– Modeling – 5,500
Additional Counts Received from
– County Engineers – 6,200– MPOs – 12,000
Total Program Counts – 45,800
Data Collection - Types of Counts
Portable Vehicle Classification Counts
Portable Vehicle Volume Counts
Manual Intersection Turning Movement Counts
Permanent Traffic Counter
Weigh-In-Motion (WIM)
ODOT Count Program
How do we (ODOT) collect traffic data? Short Term Counts
– ODOT - Collected by 3 Consultants Statewide
– Local Agency Coordination – Have acquired close 18,000 counts from the county engineers and MPOs.
ODOT Count Program How do we (ODOT) collect traffic data? Permanent Counts – ODOT/Contractor Maintained
ODOT Count Data Processing (Current) Short Term Counts
- VB.net application/Access Database
Permanent Counts
- Traffic Keeper Ohio (TKO) Client/Server

1 Cycle of Images
Roughly 27,000 miles
X 200 shots per mile
X 4 camera views
(left, front, right, & rear)
= over 21 million images
= over 11 TB of data (single copy)
1 Cycle of Images~ $ 1 million to support per cycle
< 5 cents per image really becomes
< 1 cent per image when you prorate for other data collected
Road profiles
Macrotexture
Rutting
Surface images
Spatial reference
1 Cycle of Images
All data inclusive of:
Linear Reference: County, Route, Logpoint/Milepoint
Spatial Reference: Latitude & Longitude
Date & Time Stamp
Free access to ODOT & J. Q. Public
Asset Extractions from Images
Building Asset Inventories for Barrier and Overhead Signs
71,816 barrier runs for 5,612 miles of barrier
Concrete barrier (rigid) 1,031 miles
Guardrail barrier (semi-rigid) 4,296 miles
Flexible barrier (cable rail) 284 miles
25 interns completed in 3 weeks time
Overhead Sign Inventory Collection Process
Locating signs with BOX
76
Left click and use cursor to drag a box around sign.
Recording info into database
77
Once sign or signs are boxed, now fill out the database record window.
Selecting Correct Sign
78
Select correct sign based off of image.
Legend Data & Number Of Signs
79
Select number of signs being collected.
Any wording on signs will be placed in the Legend.
Selecting Sign Supports
80
Select sign support from support menu.
Continue Collecting

1 Cycle of network road profiles
Roughly 27,000 miles
X 5280 feet per mile
X 12 elevation points per mile
X 2 wheel paths mile
= over 3.4 Billion stored profile points
Network Road Profiles
FHWA / MAP-21 Requirement to report data nationally as performance metric (IRI)
Used in OH DOT’s Pavement Management System
Leveraged to develop IRI based smoothness specifications for highway construction
International Roughness Index (IRI)Using profiles to simulate vehicle response
(What the public “feels”)
MeasuredProfile IRI
Computer Algorithm
Body Mass
Suspension Spring and Damper
Axle Mass

Network Road Profiles In-house Research
– Interstate Bridges 2.5 X rougher than Pavement– Bridges make up less than 4% of network by length– Bridges raised network IRI by almost 8%
Set the stage to develop PN 555, IRI for Bridges
