ITS Archived Data User Service (ADUS) - Implementation for Traffic Records

Transcription

1 ITS Archived Data User Service (ADUS) - Implementation for Traffic Records 27th Traffic Records Forum (Session 47) August 2, 2001 Larry Brown - Federal Highway Administration, Safety Core Business Unit 1

2 Intelligent Transportation Systems (ITS) National Emphasis Area DEFINITION - Electronic Devices, Data Processing and Communications to Improve Safety and Efficiency of Surface Transportation Federal Research and Deployment - $1.2 billion (TEA ) - ALSO, eligible for Federal-aid Funds 2

3 ITS Architecture -DATA RESOURCES 3

4 ADUS Vision Improve transportation decisions through the archiving and sharing of ITS generated data.

5 ADUS in ITS Architecture / Plan Archived Data Management Systems (ADMS) Advanced data archiving ITS as a data resource Integrated data archiving Across ITS applications Information synergy For operations and planning Comparing, forecasting, strategizing 5

6 Many Ultimate ADUS Users Safety Planners and Administrators Emergency Management Services Public Safety Organizations Private Sector Users Researchers Transportation Planners Traffic Management Operators Maintenance Providers Transit Operators Air Quality Analysts Freight & Intermodal Planners 6

7 ADUS Development (Added ADUS) National ITS Architecture Year Program Plan (US DOT) - Started National Standards Development National Standards Working Group Meetings (Spring, Summer, Fall) - Studies / Reviews / Awareness 7

9 5-Year ADUS Program ADDRESSES: Technical Issues Institutional / Organizational Issues Deployment / Integrated Systems Standards / Architecture Awareness & Technical Assistance 9

10 5-Year ADUS Program Objectives 1 Coordinate and integrate ITS & Non-ITS systems 2 Case studies - issues, costs, benefits, and uses 3 Quantify costs - build, operate, maintain archiving 4 Awareness and training 5 Research and guidance on data management 6 Define archived data needs, uses and availability 10

11 - ADUS National Standards - by: Amer. Society for Testing and Materials (ASTM) Strategic and Project Plans (2001) Focus Areas Overarching principals (e.g. Meta data, Harmonize Data Dictionaries) Traffic Monitoring Safety / Incident Mgmt Transit Commercial Vehicles / Freight 11

12 Your Regional ADUS Objectives ADUS in your Regional ITS Architectures & Plans Successful Data Archiving & Improved institutional issues (Coordination, Ownership, Liabilities) Consistent & Sharable Archived Data in Many Regions Enhance Planning, Operations, Research, and Administration Facilitate Transportation Status Reporting

13 Status of Regional Architecture Development (2001) # of Regions (prelim. results US DOT Study) Developed Ongoing Planned No near-term plans 13

14 ITS Architecture Consistency US DOT Final Rule (2001) Requires: Regional ITS Plan for ITS Deployments with Federal Funds Coordination with ITS Users 14

16 Current ITS Archived Data Users Examples Puget Sound, WA Houston, TX Chicago, IL Montgomery Co.,MD Phoenix, AZ MN/DOT TMC TXDOT U of CA McMaster U, Ontario Bur. Of Trans. Statistics WSDOT San Antonio, TX Toronto, CA Los Angeles, CA Private Businesses ETC.. 16

17 Current ITS Archived Data Uses Examples Traffic Counts Congestion Measures Construction Impacts Planning Uses Modeling Uses Research Requests Highway Operations Procedures Tracking Performance Quality Assurance ITS System Tracking Administrative Commercial Vehicle Pre-clearance Truck Weigh-In-Motion Probe Vehicle (e.g. AVI) Speed Estimates HOV Assessments Metered Ramp Flows 17

18 Current ADUS Uses Incident Impact Studies Public Safety Records Traffic & Travel Statistics/Patterns /Trends Incident Prediction Model Performance Indicators Highway Capacity Model Origin-Destination Matrices Travel Time Prediction Congestion Monitoring Regional ITS Planning HOV Alternatives Analyses Model Calibration Evaluations of: Incident Mgmt Construction Impacts ITS Evaluations Road Performance HOV Lanes Ramp Metering 18

19 Freeway Mgmt. Survey Data Collected Archived Percent None 32 Volume % Incidents % Veh. Class % Speeds % 19

20 ADUS Issues To Discuss Need to Define and Coordinate (ITS & Non-ITS) Who involved with ITS data (Stakeholders & Partners)? Data Quality Assurances? Data Tools Needed and Available? ITS Consistency, Reliability, Capabilities? Data Needs, Uses, Availability, Form? Data Sharing and Control? Details vs.trends; Raw data vs. analyzed Archiving and Sharing Liability, Privacy, Ownership 20

21 Federal ADUS Activities ( ) State of Practice Study Traffic, transit, safety, rural, planning Cross-Cutting Study Traffic, transit, safety, rural, planning ADUS for Government Report Systems Initiate Standards and Guidance development Awareness 21

22 Future Federal ADUS Activities (2002) Pilot Studies in regional architecture (Demo/FOT) Emerging ITS Data Collection Technologies Study Innovative ADUS Uses Study Early architecture implementation Awareness & Outreach / Develop Training Study Ownership, Privacy, Integrity & Liability 22

23 TRB Committee on Freeway Operations Report: Freeway Operations in 2000 and Beyond Anticipating or predicting the locations of congestion or incidents before they happen and working to prevent them will allow traffic management to make the leap from being reactive to being proactive. 23
