1 Truck Activity Visualizations In The Cloud Presented By Dr. Catherine Lawson NATMEC Improving Traffic Data Collection, Analysis, and Use June 4 7, 2012 Dallas, Texas

2 What Question Are You Trying to Answer?

3 Weigh-In-Motion (WIM) Sensors installed underneath the pavement. One line of data for every passing vehicle (based on actual axle force). Time and Date Lane Speed Vehicle Classification Wheel Load Axle Load Axle Group Load Gross Vehicle Weight Axle Spacing Total Vehicle Length Standardized TMG-2001 Data Format W Example of a WIM Record

4 wimweb wimweb is three integrated modules: Data Management Creating a central repository for WIM data. Data Quality and Inventory tools. Data Visualization Empowering WIM data. Creating meaningful charts and graphs to enhance analyses. Reporting Put WIM data to work. Maximize efficiency and effectiveness.

5 SCENARIO 1: MANAGING QUALITY CONTROL ON NATIONAL WIM DATASETS Steps to Improve Data Quality, Data Completeness, and to Automate Correction Factors

6 Where is this data being housed? Are there quality controls on this data? Is this data complete enough for me to use for analysis? Is this data from a site that is correctly calibrated?

7 Data Warehousing Upload standards-based data. Currently designed for raw ASCII WIM data files. Flexible, robust processing engine. Easily extensible to any data format (not just WIM!) Automatically processed into secure database structure. Manage terabytes of data without needing local storage and backup solutions. Reduced IT costs.

8 Data Quality wimweb Data Management Services enhance data. Automatic Data Quality Control mechanisms are in place for every file. Generate uniform, compatible data sets. Spend more time analyzing the data and less time processing it. Begin Data Load Does Data Conform to TMG- 2001? Yes Does Data Contain TMG +? No Is This Duplicate Data? No Load Data Yes Yes No Example flow for TMG-2001 Data. Flag For Review and Skip. Truncate Extra Data Flag For Review and Skip.

9 Data Inventory User-facing Data Inventory tools allow you to interact with the data files. View all the data. Visualize and easily compare metadata. Download processed data. Second-tier Data Quality Control. Checks for out-of-bounds changes in ADT. Calibration checks for WIM data. Checks for classification calibration. Powerful engine for implementing custom quality control.

10 Data Completeness Assess data completeness at a glance.

11 Data Quality By This performing station is automated in need of analysis attention. tasks we can help identify wimweb WIM can stations help identify that need troublesome attention. WIM This stations station from is showing the office. a good level of calibration. There We have are a the statistically tools to reduce insignificant the effect number of data of trucks inconsistencies out of the expected on reporting. weight bounds.

12 SCENARIO 2: DATA VISUALIZATION FOR PLANNING AND ANALYSIS Planning for Economic Development

13 What location did this data come from? Can I make graphs of the data? How can I filter the data, so I can see only what I want? Can I explore the characteristics of the data?

14 Google Maps Integration Simple, clean, and familiar user interface. Provides immediate recognition of station location. Identify nearby stations for data comparisons. Compatible with all operating systems and current web browsers.

15 Line and Column Graphs

16 Weight Distribution Graphs and Data Tables

17 SCENARIO 3: DATA VISUALIZATION AND REPORTING FOR COMPLIANCE AND ENFORCEMENT 3 Steps to Increase Overweight Vehicle Compliance and Pavement Life.

18 How do I best use my assets to maximize vehicle compliance? Can I predict over-weight activity? Can I schedule deployment patterns in advance? Can I find over-weight trucks in real-time?

19 Statewide Forecasting Plan deployment scheduling in advance. Ranking of each station by a customizable composite index. Using historical data to increase success.

20 Individual Station Reporting Visualizations span bi-directional tables. You know which direction more overweight vehicles are travelling. Viewable by GVW or Axle-Weight.

21 Real-Time Weight Visualization Quickly assess vehicle weight and configuration. With access to real-time data, wimweb can display instant visualizations to enforcement units. wimweb can enhance speed and accuracy in vehicle size and weight enforcement.
