Enterprise Access to Traffic Information Michael Bish Matt Hiland Tony Pietropola
Traffic Information Access (TRINA) Background Project Objectives Approach Outcome
TRINA Background Traffic information is in high demand Traffic information is in high demand Both Traffic Volume and Vehicle Classification data Used by many NDOT divisions and districts Planning Safety HPMS Used by the public and local governments Traffic control engineers Real estate Marketing Banks
TRINA Background NDOT Annual Traffic Report NDOT Annual Traffic Report Was the primary source of traffic information Contains lots of information, but Large paper document Difficult and expensive to produce Difficult to distribute Sometimes difficult to interpret Not easily integrated with other data Traffic Information Systems Division (TISD) personnel spent large amounts of time responding to requests for data nearly two full-time equivalents.
TRINA Objectives Provide easy access to traffic data for NDOT and the public Deliver traffic information electronically Build an extensible foundation for integrating traffic data with GIS maps and other business unit data Demonstrate the effectiveness of NDOT s use of state-of-the-art technology to efficiently serve its public mission
TRINA Benefits More efficient use of TISD personnel time More effective application of traffic data Increased value of traffic data through its increased use across NDOT
TRINA Approach Phase 1 Develop a web-based application that provides basic mapping and reporting of traffic count and classification data to all of NDOT via the intranet Establish a modular, expandable application architecture that will support the addition of other applications
TRINA Approach Requirements Work with end users and stakeholders to define what the application must do Traffic Information Systems Division GIS Section, Location Division Data Processing Roadway Systems Division Also includes functionality envisioned for future phases Helps prioritizing and planning budgets Helps improve the system design
TRINA Requirements
TRINA Approach Technical Design Technical Design Coding conventions System architecture Data design Descriptions of individual files GUI design Prototype Provides sufficient detail so that Developers and client agree on the approach and design Can divide and assign tasks Future programmers can understand how the app works

TRINA Technical Design
TRINA Implementation Deployed on NDOT intranet Technology: Windows 2000 IIS ASP GeoMedia WebMap Oracle Spatial
TRINA Implementation Spatial information portal site established Future applications can be easily added
TRINA Implementation Users can select traffic count locations by Clicking on map to select one or multiple stations Keying in Station ID District Sub-District County Urban Area User Defined Area
TRINA Implementation Multi-selection list shows basic information about each station User selects a station from the list to display reporting options
TRINA Implementation Report options vary according to type of station selected Available reports for short-term term stations include: AADT History Hourly Volumes Vehicle Classification Data Station Details
TRINA Implementation Available reports for continuous stations include: Monthly Summary Comprehensive Annual Summary Average Hourly Volumes Vehicle Classification Data Station Details
TRINA Implementation Comprehensive Online Help is included
TRINA Implementation A quick link to Contacts is provided for questions and user feedback User feedback will be incorporated into Phase 2 requirements
TRINA Approach Phase 2 Enhance and expand TRINA functionality Make portions of TRINA available to the general public via the internet
TRINA Outcome Mike Lawson, Traffic Information Systems Division Chief: It s more timely and frees up people to do more analysis. It s a win/win for users and the department. Eric Warmath, GIS Coordinator: The six-month project was completed on time and on budget using existing hardware and software It was a great team effort.
