TMC Data Capture for Performance and Mobility MeasuresBooz Allen HamiltonHNTBTRAC-UW
Project Team • Booz Allen Hamilton • HNTB Corporation • University of Washington’s Transportation Center (TRAC-UW) • FreeAhead • TÜV Rheinland
Presentation Outline • Project Background • Scope of Work • Results • Questions and Answers Source: WSDOT Flickr
Problem Statement • Lack of accurate data inhibits ability to monitor and measure TMC performance • As data gathering becomes more automated, potential use of the data increases • Need adequate and accurate means of collecting and archiving performance, mobility and incident management data
Scope of Work • Develop a Guidebook • Concepts, • Methods, • Techniques, and • Procedures for collecting and archiving TMC operation data
Scope of Work • Provide technical guidance and recommended practices for TMC performance • Monitoring, • Evaluating and • Reporting For transportation system mobility and traffic incident management
Scope of Work • Include: • Case studies as illustrative examples • Identify best practices and lessons learned, • at system level • for specific scenarios or locations
Guidebook Audience and Users • Targeted end users • TMC managers, • Supervisors • Operators • Also anyone with a role in TMS/TMC • performance monitoring, • evaluation, and • reporting
Guidebook Audience and Users • This includes: • State and local DOTs • Metropolitan Planning Organizations • Transit agencies • TMC contractors • Others having a role in the TSM&O • Representatives of EOCs, enforcement agencies and others having a role in emergency transportation operations
Approach to Developing Guidebook • Conduct literature search, • Survey practitioners, and • Use the experience of the research team and project panel • Identified: • Needs and starting points of the potential users • Key issues and challenges that are common among TMCs
Approach to Developing Guidebook • Acknowledges the diversity of TMCs • Activities performed • Data currently collected • Current expectations for reporting performance • Experience with collecting, reporting data • Provide a process to bridge the gap in capabilities between these diverse TMCs
Literature Review • A large volume of literature exists on performance measures for TMC activities and roadway mobility • Available through: • FHWA TIM web site • FHWA Operations web site • NCHRP • NTOC • General web publications (e.g., TAMU Urban Mobility report)
Literature • Performance Measures • Output measures • What activities are being undertaken • Outcome measures • What is happening on the roadway (volume/delay) • Supporting documents • Data processing, quality control procedures, and database design, communications design and requirements • Frequently correspond to very specific databases
Practitioners • TMCs interviewed ranged from • Those very experienced with performance monitoring (the bleeding edge), to • Those just getting started with performance monitoring, and • Several TMCs somewhere in the middle
Practitioner Survey Results • Motivations for performance reporting • Legislative mandates • Agency wide performance initiatives • Formal business linkage – particularly for operations • Use reporting to improve agency cooperation, employee actions, or to judge contractor performance • Plan future investments / resource allocation • Quantification of benefits • To assist in defense of program funding • To assist in competition for additional funding with infrastructure projects
Practitioner Survey Results • Performance reporting generally grows as follows: • What we are doing? • How well are we doing those activities? • What is happening on the roadway? • How is what we are doing effecting what is happening on the roadway?
Practitioner Survey Results • Initial reporting activities • Description of activities being performed • Number of incidents responded to by size of incident • Number of DMS messages posted • Size and operational condition of equipment/staff • Number of devices / staff • Number of operating devices / staff on duty
Practitioner Survey Results • Second level TMC reporting activities generally include • Detailed quantification of activities being performed • Review resource deployment, trends, staff review • Detailed incident descriptives for trend reporting • Log of incident types, timestamps, actions taken • Number of incidents lasting more than 90 minutes • Time required to post DMS messages • Captured video of event activities • Size and operational condition of equipment/staff • Time required to repair equipment
Practitioner Survey Results • Second Level Reporting: Mobility Reporting • Volumes, delays, reliability • Reported as travel times, congestion by location, revenue (HOT lanes), severe weather response • Most TMCs are now reporting current conditions • Not all TMCs are actively summarizing / reporting roadway performance • Increasing use of private sector probe data • Still need agency collected volume data
Practitioner Survey Results • Third Level Reporting: advanced TMCs are actively working on improved analysis and reporting of • Cause, effect, timing of disruptions • Responses to those disruptions • The effect / effectiveness of those responses
Third Level Activities • “After action” reports across agencies and summaries for improving agency response and interaction • Particularly use of video of incident scenes • Before and after reports on road conditions after new activities are undertaken • Benefits analyses for programs (cross cutting analyses)
Guidebook Overview • Two volumes: • Guidebook • Reference Manual • Different than originally planned • More effectively meets the needs of different audiences
Final Report Overview • Two volumes • Set up for users to read chapters as needed • Find what you want quickly • Helps reader consider: • Regional / local concerns • Rural / urban / suburban differences • Geographic coverage area • Current vs. future data availability • Budget justifications • Basic vs. advanced measures discussed
The Guidebook Volume • Guidebook: • Executives and upper management the audience • An overview of measures and issues • The “what” and “why” of performance monitoring • Helps an agency get started in performance management
Reference Manual Volume • The details of “how” to do performance management • A synopsis of each performance measure (or group of related performance measures), • An overview of each measure’s • Usefulness, • Required data sources, • Primary calculation steps or equations, • Examples of useful variations of the measure, • Issues or implementation considerations • Example applications from TMCs around the country
Both Volumes • Contain introductory material • Acknowledge that each TMC is different • Provide advice that says to report • On activities performed • Over the geographic area the TMC covers • Start with “basic” measures, and grow to become more advanced to meet changing TMC needs
Both Volumes • Technical material split into four sections, reflecting potential TMC roles and reporting needs • TMC operations • Incident response • System mobility • Cross-cutting • One chapter per set of measures
Other Material • Guidebook • Lessons learned • General guidance and considerations • Reference Manual • Case studies • Examples • References to more details / examples
Recommended Approach • Basic measures • Simple • Common to all TMCs working in a topic area • Next compute additional measures from basic data • Supplementary information to aid management • Finally, produce advanced measures • Meet specialized needs
TMC Have Different Roles & Responsibilities • Performance measures should reflect the activities performed by that TMC • TMC Operations • Incident Response • Mobility • Cross Cutting
TMC Operations Chapter • Purpose & need for measures • Categories of measures • ITS infrastructure • TMC operational responsibilities • Staff performance • Specialized operations • Future trends • Data collection and management
Purpose • Measure the TMC’s ability to meet goals and objectives related to performing its key functions of • Monitoring, • Operating, and • Maintaining traffic management and traveler information systems
